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.

---all::
-	Fetch all remotes.
-
--a::
---append::
-	Append ref names and object names of fetched refs to the
-	existing contents of `.git/FETCH_HEAD`.  Without this
-	option old data in `.git/FETCH_HEAD` will be overwritten.
-
---depth=<depth>::
-	Limit fetching to the specified number of commits from the tip of
-	each remote branch history. If fetching to a 'shallow' repository
-	created by `git clone` with `--depth=<depth>` option (see
-	linkgit:git-clone[1]), deepen or shorten the history to the specified
-	number of commits. Tags for the deepened commits are not fetched.
-
---deepen=<depth>::
-	Similar to --depth, except it specifies the number of commits
-	from the current shallow boundary instead of from the tip of
-	each remote branch history.
-
---shallow-since=<date>::
-	Deepen or shorten the history of a shallow repository to
-	include all reachable commits after <date>.
-
---shallow-exclude=<revision>::
-	Deepen or shorten the history of a shallow repository to
-	exclude commits reachable from a specified remote branch or tag.
-	This option can be specified multiple times.
-
---unshallow::
-	If the source repository is complete, convert a shallow
-	repository to a complete one, removing all the limitations
-	imposed by shallow repositories.
-+
-If the source repository is shallow, fetch as much as possible so that
-the current repository has the same history as the source repository.
-
---update-shallow::
-	By default when fetching from a shallow repository,
-	`git fetch` refuses refs that require updating
-	.git/shallow. This option updates .git/shallow and accept such
-	refs.
-
---negotiation-tip=<commit|glob>::
-	By default, Git will report, to the server, commits reachable
-	from all local refs to find common commits in an attempt to
-	reduce the size of the to-be-received packfile. If specified,
-	Git will only report commits reachable from the given tips.
-	This is useful to speed up fetches when the user knows which
-	local ref is likely to have commits in common with the
-	upstream ref being fetched.
-+
-This option may be specified more than once; if so, Git will report
-commits reachable from any of the given commits.
-+
-The argument to this option may be a glob on ref names, a ref, or the (possibly
-abbreviated) SHA-1 of a commit. Specifying a glob is equivalent to specifying
-this option multiple times, one for each matching ref name.
-+
-See also the `fetch.negotiationAlgorithm` configuration variable
-documented in linkgit:git-config[1].
-
---dry-run::
-	Show what would be done, without making any changes.
-
-ifndef::git-pull[]
---[no-]write-fetch-head::
-	Write the list of remote refs fetched in the `FETCH_HEAD`
-	file directly under `$GIT_DIR`.  This is the default.
-	Passing `--no-write-fetch-head` from the command line tells
-	Git not to write the file.  Under `--dry-run` option, the
-	file is never written.
-endif::git-pull[]
-
--f::
---force::
-	When 'git fetch' is used with `<src>:<dst>` refspec it may
-	refuse to update the local branch as discussed
-ifdef::git-pull[]
-	in the `<refspec>` part of the linkgit:git-fetch[1]
-	documentation.
-endif::git-pull[]
-ifndef::git-pull[]
-	in the `<refspec>` part below.
-endif::git-pull[]
-	This option overrides that check.
-
--k::
---keep::
-	Keep downloaded pack.
-
-ifndef::git-pull[]
---multiple::
-	Allow several <repository> and <group> arguments to be
-	specified. No <refspec>s may be specified.
-
---[no-]auto-maintenance::
---[no-]auto-gc::
-	Run `git maintenance run --auto` at the end to perform automatic
-	repository maintenance if needed. (`--[no-]auto-gc` is a synonym.)
-	This is enabled by default.
-
---[no-]write-commit-graph::
-	Write a commit-graph after fetching. This overrides the config
-	setting `fetch.writeCommitGraph`.
-endif::git-pull[]
-
--p::
---prune::
-	Before fetching, remove any remote-tracking references that no
-	longer exist on the remote.  Tags are not subject to pruning
-	if they are fetched only because of the default tag
-	auto-following or due to a --tags option.  However, if tags
-	are fetched due to an explicit refspec (either on the command
-	line or in the remote configuration, for example if the remote
-	was cloned with the --mirror option), then they are also
-	subject to pruning. Supplying `--prune-tags` is a shorthand for
-	providing the tag refspec.
-ifndef::git-pull[]
-+
-See the PRUNING section below for more details.
-
--P::
---prune-tags::
-	Before fetching, remove any local tags that no longer exist on
-	the remote if `--prune` is enabled. This option should be used
-	more carefully, unlike `--prune` it will remove any local
-	references (local tags) that have been created. This option is
-	a shorthand for providing the explicit tag refspec along with
-	`--prune`, see the discussion about that in its documentation.
-+
-See the PRUNING section below for more details.
-
-endif::git-pull[]
-
-ifndef::git-pull[]
--n::
-endif::git-pull[]
---no-tags::
-	By default, tags that point at objects that are downloaded
-	from the remote repository are fetched and stored locally.
-	This option disables this automatic tag following. The default
-	behavior for a remote may be specified with the remote.<name>.tagOpt
-	setting. See linkgit:git-config[1].
-
---refmap=<refspec>::
-	When fetching refs listed on the command line, use the
-	specified refspec (can be given more than once) to map the
-	refs to remote-tracking branches, instead of the values of
-	`remote.*.fetch` configuration variables for the remote
-	repository.  Providing an empty `<refspec>` to the
-	`--refmap` option causes Git to ignore the configured
-	refspecs and rely entirely on the refspecs supplied as
-	command-line arguments. See section on "Configured Remote-tracking
-	Branches" for details.
-
--t::
---tags::
-	Fetch all tags from the remote (i.e., fetch remote tags
-	`refs/tags/*` into local tags with the same name), in addition
-	to whatever else would otherwise be fetched.  Using this
-	option alone does not subject tags to pruning, even if --prune
-	is used (though tags may be pruned anyway if they are also the
-	destination of an explicit refspec; see `--prune`).
-
-ifndef::git-pull[]
---recurse-submodules[=yes|on-demand|no]::
-	This option controls if and under what conditions new commits of
-	populated submodules should be fetched too. It can be used as a
-	boolean option to completely disable recursion when set to 'no' or to
-	unconditionally recurse into all populated submodules when set to
-	'yes', which is the default when this option is used without any
-	value. Use 'on-demand' to only recurse into a populated submodule
-	when the superproject retrieves a commit that updates the submodule's
-	reference to a commit that isn't already in the local submodule
-	clone. By default, 'on-demand' is used, unless
-	`fetch.recurseSubmodules` is set (see linkgit:git-config[1]).
-endif::git-pull[]
-
--j::
---jobs=<n>::
-	Number of parallel children to be used for all forms of fetching.
-+
-If the `--multiple` option was specified, the different remotes will be fetched
-in parallel. If multiple submodules are fetched, they will be fetched in
-parallel. To control them independently, use the config settings
-`fetch.parallel` and `submodule.fetchJobs` (see linkgit:git-config[1]).
-+
-Typically, parallel recursive and multi-remote fetches will be faster. By
-default fetches are performed sequentially, not in parallel.
-
-ifndef::git-pull[]
---no-recurse-submodules::
-	Disable recursive fetching of submodules (this has the same effect as
-	using the `--recurse-submodules=no` option).
-endif::git-pull[]
-
---set-upstream::
-	If the remote is fetched successfully, add upstream
-	(tracking) reference, used by argument-less
-	linkgit:git-pull[1] and other commands. For more information,
-	see `branch.<name>.merge` and `branch.<name>.remote` in
-	linkgit:git-config[1].
-
-ifndef::git-pull[]
---submodule-prefix=<path>::
-	Prepend <path> to paths printed in informative messages
-	such as "Fetching submodule foo".  This option is used
-	internally when recursing over submodules.
-
---recurse-submodules-default=[yes|on-demand]::
-	This option is used internally to temporarily provide a
-	non-negative default value for the --recurse-submodules
-	option.  All other methods of configuring fetch's submodule
-	recursion (such as settings in linkgit:gitmodules[5] and
-	linkgit:git-config[1]) override this option, as does
-	specifying --[no-]recurse-submodules directly.
-
--u::
---update-head-ok::
-	By default 'git fetch' refuses to update the head which
-	corresponds to the current branch.  This flag disables the
-	check.  This is purely for the internal use for 'git pull'
-	to communicate with 'git fetch', and unless you are
-	implementing your own Porcelain you are not supposed to
-	use it.
-endif::git-pull[]
-
---upload-pack <upload-pack>::
-	When given, and the repository to fetch from is handled
-	by 'git fetch-pack', `--exec=<upload-pack>` is passed to
-	the command to specify non-default path for the command
-	run on the other end.
-
-ifndef::git-pull[]
--q::
---quiet::
-	Pass --quiet to git-fetch-pack and silence any other internally
-	used git commands. Progress is not reported to the standard error
-	stream.
-
--v::
---verbose::
-	Be verbose.
-endif::git-pull[]
-
---progress::
-	Progress status is reported on the standard error stream
-	by default when it is attached to a terminal, unless -q
-	is specified. This flag forces progress status even if the
-	standard error stream is not directed to a terminal.
-
--o <option>::
---server-option=<option>::
-	Transmit the given string to the server when communicating using
-	protocol version 2.  The given string must not contain a NUL or LF
-	character.  The server's handling of server options, including
-	unknown ones, is server-specific.
-	When multiple `--server-option=<option>` are given, they are all
-	sent to the other side in the order listed on the command line.
-
---show-forced-updates::
-	By default, git checks if a branch is force-updated during
-	fetch. This can be disabled through fetch.showForcedUpdates, but
-	the --show-forced-updates option guarantees this check occurs.
-	See linkgit:git-config[1].
-
---no-show-forced-updates::
-	By default, git checks if a branch is force-updated during
-	fetch. Pass --no-show-forced-updates or set fetch.showForcedUpdates
-	to false to skip this check for performance reasons. If used during
-	'git-pull' the --ff-only option will still check for forced updates
-	before attempting a fast-forward update. See linkgit:git-config[1].
-
--4::
---ipv4::
-	Use IPv4 addresses only, ignoring IPv6 addresses.
-
--6::
---ipv6::
-	Use IPv6 addresses only, ignoring IPv4 addresses.
