chore(3p/git): Unvendor git and track patches instead r/2903

This was vendored a long time ago under the expectation that keeping
it in sync with cgit would be easier this way, but it has proven not
to be a big issue.

On the other hand, a vendored copy of git is an annoying maintenance
burden. It is much easier to rebase the single (dottime) patch that we
have.

This removes the vendored copy of git and instead passes the git
source code to cgit via `pkgs.srcOnly`, which includes the applied
patch so that cgit can continue rendering dottime.

-DESCRIPTION
------------
-Create a new commit containing the current contents of the index and
-the given log message describing the changes. The new commit is a
-direct child of HEAD, usually the tip of the current branch, and the
-branch is updated to point to it (unless no branch is associated with
-the working tree, in which case HEAD is "detached" as described in
-linkgit:git-checkout[1]).
-
-The content to be committed can be specified in several ways:
-
-1. by using linkgit:git-add[1] to incrementally "add" changes to the
-   index before using the 'commit' command (Note: even modified files
-   must be "added");
-
-2. by using linkgit:git-rm[1] to remove files from the working tree
-   and the index, again before using the 'commit' command;
-
-3. by listing files as arguments to the 'commit' command
-   (without --interactive or --patch switch), in which
-   case the commit will ignore changes staged in the index, and instead
-   record the current content of the listed files (which must already
-   be known to Git);
-
-4. by using the -a switch with the 'commit' command to automatically
-   "add" changes from all known files (i.e. all files that are already
-   listed in the index) and to automatically "rm" files in the index
-   that have been removed from the working tree, and then perform the
-   actual commit;
-
-5. by using the --interactive or --patch switches with the 'commit' command
-   to decide one by one which files or hunks should be part of the commit
-   in addition to contents in the index,
-   before finalizing the operation. See the ``Interactive Mode'' section of
-   linkgit:git-add[1] to learn how to operate these modes.
-
-The `--dry-run` option can be used to obtain a
-summary of what is included by any of the above for the next
-commit by giving the same set of parameters (options and paths).
-
-If you make a commit and then find a mistake immediately after
-that, you can recover from it with 'git reset'.
-
-
-OPTIONS
--------
--a::
---all::
-	Tell the command to automatically stage files that have
-	been modified and deleted, but new files you have not
-	told Git about are not affected.
-
--p::
---patch::
-	Use the interactive patch selection interface to chose
-	which changes to commit. See linkgit:git-add[1] for
-	details.
-
--C <commit>::
---reuse-message=<commit>::
-	Take an existing commit object, and reuse the log message
-	and the authorship information (including the timestamp)
-	when creating the commit.
-
--c <commit>::
---reedit-message=<commit>::
-	Like '-C', but with `-c` the editor is invoked, so that
-	the user can further edit the commit message.
-
---fixup=<commit>::
-	Construct a commit message for use with `rebase --autosquash`.
-	The commit message will be the subject line from the specified
-	commit with a prefix of "fixup! ".  See linkgit:git-rebase[1]
-	for details.
-
---squash=<commit>::
-	Construct a commit message for use with `rebase --autosquash`.
-	The commit message subject line is taken from the specified
-	commit with a prefix of "squash! ".  Can be used with additional
-	commit message options (`-m`/`-c`/`-C`/`-F`). See
-	linkgit:git-rebase[1] for details.
-
---reset-author::
-	When used with -C/-c/--amend options, or when committing after a
-	conflicting cherry-pick, declare that the authorship of the
-	resulting commit now belongs to the committer. This also renews
-	the author timestamp.
-
---short::
-	When doing a dry-run, give the output in the short-format. See
-	linkgit:git-status[1] for details. Implies `--dry-run`.
-
---branch::
-	Show the branch and tracking info even in short-format.
-
---porcelain::
-	When doing a dry-run, give the output in a porcelain-ready
-	format. See linkgit:git-status[1] for details. Implies
-	`--dry-run`.
-
---long::
-	When doing a dry-run, give the output in the long-format.
-	Implies `--dry-run`.
-
--z::
---null::
-	When showing `short` or `porcelain` status output, print the
-	filename verbatim and terminate the entries with NUL, instead of LF.
-	If no format is given, implies the `--porcelain` output format.
-	Without the `-z` option, filenames with "unusual" characters are
-	quoted as explained for the configuration variable `core.quotePath`
-	(see linkgit:git-config[1]).
-
--F <file>::
---file=<file>::
-	Take the commit message from the given file.  Use '-' to
-	read the message from the standard input.
-
---author=<author>::
-	Override the commit author. Specify an explicit author using the
-	standard `A U Thor <author@example.com>` format. Otherwise <author>
-	is assumed to be a pattern and is used to search for an existing
-	commit by that author (i.e. rev-list --all -i --author=<author>);
-	the commit author is then copied from the first such commit found.
-
---date=<date>::
-	Override the author date used in the commit.
-
--m <msg>::
---message=<msg>::
-	Use the given <msg> as the commit message.
-	If multiple `-m` options are given, their values are
-	concatenated as separate paragraphs.
-+
-The `-m` option is mutually exclusive with `-c`, `-C`, and `-F`.
-
--t <file>::
---template=<file>::
-	When editing the commit message, start the editor with the
-	contents in the given file.  The `commit.template` configuration
-	variable is often used to give this option implicitly to the
-	command.  This mechanism can be used by projects that want to
-	guide participants with some hints on what to write in the message
-	in what order.  If the user exits the editor without editing the
-	message, the commit is aborted.  This has no effect when a message
-	is given by other means, e.g. with the `-m` or `-F` options.
-
--s::
---signoff::
-	Add Signed-off-by line by the committer at the end of the commit
-	log message.  The meaning of a signoff depends on the project,
-	but it typically certifies that committer has
-	the rights to submit this work under the same license and
-	agrees to a Developer Certificate of Origin
-	(see http://developercertificate.org/ for more information).
-
--n::
---no-verify::
-	This option bypasses the pre-commit and commit-msg hooks.
-	See also linkgit:githooks[5].
-
---allow-empty::
-	Usually recording a commit that has the exact same tree as its
-	sole parent commit is a mistake, and the command prevents you
-	from making such a commit.  This option bypasses the safety, and
-	is primarily for use by foreign SCM interface scripts.
-
---allow-empty-message::
-       Like --allow-empty this command is primarily for use by foreign
-       SCM interface scripts. It allows you to create a commit with an
-       empty commit message without using plumbing commands like
-       linkgit:git-commit-tree[1].
-
---cleanup=<mode>::
-	This option determines how the supplied commit message should be
-	cleaned up before committing.  The '<mode>' can be `strip`,
-	`whitespace`, `verbatim`, `scissors` or `default`.
-+
---
-strip::
-	Strip leading and trailing empty lines, trailing whitespace,
-	commentary and collapse consecutive empty lines.
-whitespace::
-	Same as `strip` except #commentary is not removed.
-verbatim::
-	Do not change the message at all.
-scissors::
-	Same as `whitespace` except that everything from (and including)
-	the line found below is truncated, if the message is to be edited.
-	"`#`" can be customized with core.commentChar.
-
-		# ------------------------ >8 ------------------------
-
-default::
-	Same as `strip` if the message is to be edited.
-	Otherwise `whitespace`.
---
-+
-The default can be changed by the `commit.cleanup` configuration
-variable (see linkgit:git-config[1]).
-
--e::
---edit::
-	The message taken from file with `-F`, command line with
-	`-m`, and from commit object with `-C` are usually used as
-	the commit log message unmodified. This option lets you
-	further edit the message taken from these sources.
-
---no-edit::
-	Use the selected commit message without launching an editor.
-	For example, `git commit --amend --no-edit` amends a commit
-	without changing its commit message.
-
---amend::
-	Replace the tip of the current branch by creating a new
-	commit. The recorded tree is prepared as usual (including
-	the effect of the `-i` and `-o` options and explicit
-	pathspec), and the message from the original commit is used
-	as the starting point, instead of an empty message, when no
-	other message is specified from the command line via options
-	such as `-m`, `-F`, `-c`, etc.  The new commit has the same
-	parents and author as the current one (the `--reset-author`
-	option can countermand this).
-+
---
-It is a rough equivalent for:
-------
-	$ git reset --soft HEAD^
-	$ ... do something else to come up with the right tree ...
-	$ git commit -c ORIG_HEAD
-
-------
-but can be used to amend a merge commit.
---
-+
-You should understand the implications of rewriting history if you
-amend a commit that has already been published.  (See the "RECOVERING
-FROM UPSTREAM REBASE" section in linkgit:git-rebase[1].)
-
---no-post-rewrite::
-	Bypass the post-rewrite hook.
-
--i::
---include::
-	Before making a commit out of staged contents so far,
-	stage the contents of paths given on the command line
-	as well.  This is usually not what you want unless you
-	are concluding a conflicted merge.
-
--o::
---only::
-	Make a commit by taking the updated working tree contents
-	of the paths specified on the
-	command line, disregarding any contents that have been
-	staged for other paths. This is the default mode of operation of
-	'git commit' if any paths are given on the command line,
-	in which case this option can be omitted.
-	If this option is specified together with `--amend`, then
-	no paths need to be specified, which can be used to amend
-	the last commit without committing changes that have
-	already been staged. If used together with `--allow-empty`
-	paths are also not required, and an empty commit will be created.
-
---pathspec-from-file=<file>::
-	Pathspec is passed in `<file>` instead of commandline args. If
-	`<file>` is exactly `-` then standard input is used. Pathspec
-	elements are separated by LF or CR/LF. Pathspec elements can be
-	quoted as explained for the configuration variable `core.quotePath`
-	(see linkgit:git-config[1]). See also `--pathspec-file-nul` and
-	global `--literal-pathspecs`.
-
---pathspec-file-nul::
-	Only meaningful with `--pathspec-from-file`. Pathspec elements are
-	separated with NUL character and all other characters are taken
-	literally (including newlines and quotes).
-
--u[<mode>]::
---untracked-files[=<mode>]::
-	Show untracked files.
-+
---
-The mode parameter is optional (defaults to 'all'), and is used to
-specify the handling of untracked files; when -u is not used, the
-default is 'normal', i.e. show untracked files and directories.
-
-The possible options are:
-
-	- 'no'     - Show no untracked files
-	- 'normal' - Shows untracked files and directories
-	- 'all'    - Also shows individual files in untracked directories.
-
-The default can be changed using the status.showUntrackedFiles
-configuration variable documented in linkgit:git-config[1].
---
-
--v::
---verbose::
-	Show unified diff between the HEAD commit and what
-	would be committed at the bottom of the commit message
-	template to help the user describe the commit by reminding
-	what changes the commit has.
-	Note that this diff output doesn't have its
-	lines prefixed with '#'. This diff will not be a part
-	of the commit message. See the `commit.verbose` configuration
-	variable in linkgit:git-config[1].
-+
-If specified twice, show in addition the unified diff between
-what would be committed and the worktree files, i.e. the unstaged
-changes to tracked files.
-
--q::
---quiet::
-	Suppress commit summary message.
-
---dry-run::
-	Do not create a commit, but show a list of paths that are
-	to be committed, paths with local changes that will be left
-	uncommitted and paths that are untracked.
-
---status::
-	Include the output of linkgit:git-status[1] in the commit
-	message template when using an editor to prepare the commit
-	message.  Defaults to on, but can be used to override
-	configuration variable commit.status.
-
---no-status::
-	Do not include the output of linkgit:git-status[1] in the
-	commit message template when using an editor to prepare the
-	default commit message.
-
--S[<keyid>]::
---gpg-sign[=<keyid>]::
---no-gpg-sign::
-	GPG-sign commits. The `keyid` argument is optional and
-	defaults to the committer identity; if specified, it must be
-	stuck to the option without a space. `--no-gpg-sign` is useful to
-	countermand both `commit.gpgSign` configuration variable, and
-	earlier `--gpg-sign`.
-
-\--::
-	Do not interpret any more arguments as options.
-
-<pathspec>...::
-	When pathspec is given on the command line, commit the contents of
-	the files that match the pathspec without recording the changes
-	already added to the index. The contents of these files are also
-	staged for the next commit on top of what have been staged before.
-+
-For more details, see the 'pathspec' entry in linkgit:gitglossary[7].
-
-EXAMPLES
---------
-When recording your own work, the contents of modified files in
-your working tree are temporarily stored to a staging area
-called the "index" with 'git add'.  A file can be
-reverted back, only in the index but not in the working tree,
-to that of the last commit with `git restore --staged <file>`,
-which effectively reverts 'git add' and prevents the changes to
-this file from participating in the next commit.  After building
-the state to be committed incrementally with these commands,
-`git commit` (without any pathname parameter) is used to record what
-has been staged so far.  This is the most basic form of the
-command.  An example:
-
-------------
-$ edit hello.c
-$ git rm goodbye.c
-$ git add hello.c
-$ git commit
-------------
-
-Instead of staging files after each individual change, you can
-tell `git commit` to notice the changes to the files whose
-contents are tracked in
-your working tree and do corresponding `git add` and `git rm`
-for you.  That is, this example does the same as the earlier
-example if there is no other change in your working tree:
-
-------------
-$ edit hello.c
-$ rm goodbye.c
-$ git commit -a
-------------
-
-The command `git commit -a` first looks at your working tree,
-notices that you have modified hello.c and removed goodbye.c,
-and performs necessary `git add` and `git rm` for you.
-
-After staging changes to many files, you can alter the order the
-changes are recorded in, by giving pathnames to `git commit`.
-When pathnames are given, the command makes a commit that
-only records the changes made to the named paths:
-
-------------
-$ edit hello.c hello.h
-$ git add hello.c hello.h
-$ edit Makefile
-$ git commit Makefile
-------------
-
-This makes a commit that records the modification to `Makefile`.
-The changes staged for `hello.c` and `hello.h` are not included
-in the resulting commit.  However, their changes are not lost --
-they are still staged and merely held back.  After the above
-sequence, if you do:
-
-------------
-$ git commit
-------------
-
-this second commit would record the changes to `hello.c` and
-`hello.h` as expected.
-
-After a merge (initiated by 'git merge' or 'git pull') stops
-because of conflicts, cleanly merged
-paths are already staged to be committed for you, and paths that
-conflicted are left in unmerged state.  You would have to first
-check which paths are conflicting with 'git status'
-and after fixing them manually in your working tree, you would
-stage the result as usual with 'git add':
-
-------------
-$ git status | grep unmerged
-unmerged: hello.c
-$ edit hello.c
-$ git add hello.c
-------------
-
-After resolving conflicts and staging the result, `git ls-files -u`
-would stop mentioning the conflicted path.  When you are done,
-run `git commit` to finally record the merge:
-
-------------
-$ git commit
-------------
-
-As with the case to record your own changes, you can use `-a`
-option to save typing.  One difference is that during a merge
-resolution, you cannot use `git commit` with pathnames to
-alter the order the changes are committed, because the merge
-should be recorded as a single commit.  In fact, the command
-refuses to run when given pathnames (but see `-i` option).
-
-COMMIT INFORMATION
-------------------
-
-Author and committer information is taken from the following environment
-variables, if set:
-
-	GIT_AUTHOR_NAME
-	GIT_AUTHOR_EMAIL
-	GIT_AUTHOR_DATE
-	GIT_COMMITTER_NAME
-	GIT_COMMITTER_EMAIL
-	GIT_COMMITTER_DATE
-
-(nb "<", ">" and "\n"s are stripped)
-
-The author and committer names are by convention some form of a personal name
-(that is, the name by which other humans refer to you), although Git does not
-enforce or require any particular form. Arbitrary Unicode may be used, subject
-to the constraints listed above. This name has no effect on authentication; for
-that, see the `credential.username` variable in linkgit:git-config[1].
-
-In case (some of) these environment variables are not set, the information
-is taken from the configuration items `user.name` and `user.email`, or, if not
-present, the environment variable EMAIL, or, if that is not set,
-system user name and the hostname used for outgoing mail (taken
-from `/etc/mailname` and falling back to the fully qualified hostname when
-that file does not exist).
-
-The `author.name` and `committer.name` and their corresponding email options
-override `user.name` and `user.email` if set and are overridden themselves by
-the environment variables.
-
-The typical usage is to set just the `user.name` and `user.email` variables;
-the other options are provided for more complex use cases.
-
-:git-commit: 1
-include::date-formats.txt[]
-
-DISCUSSION
-----------
-
-Though not required, it's a good idea to begin the commit message
-with a single short (less than 50 character) line summarizing the
-change, followed by a blank line and then a more thorough description.
-The text up to the first blank line in a commit message is treated
-as the commit title, and that title is used throughout Git.
-For example, linkgit:git-format-patch[1] turns a commit into email, and it uses
-the title on the Subject line and the rest of the commit in the body.
-
-include::i18n.txt[]
-
-ENVIRONMENT AND CONFIGURATION VARIABLES
----------------------------------------
-The editor used to edit the commit log message will be chosen from the
-`GIT_EDITOR` environment variable, the core.editor configuration variable, the
-`VISUAL` environment variable, or the `EDITOR` environment variable (in that
-order).  See linkgit:git-var[1] for details.
-
-HOOKS
------
-This command can run `commit-msg`, `prepare-commit-msg`, `pre-commit`,
-`post-commit` and `post-rewrite` hooks.  See linkgit:githooks[5] for more
-information.
-
-FILES
------
-
-`$GIT_DIR/COMMIT_EDITMSG`::
-	This file contains the commit message of a commit in progress.
-	If `git commit` exits due to an error before creating a commit,
-	any commit message that has been provided by the user (e.g., in
-	an editor session) will be available in this file, but will be
-	overwritten by the next invocation of `git commit`.
