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.

-diff.autoRefreshIndex::
-	When using 'git diff' to compare with work tree
-	files, do not consider stat-only change as changed.
-	Instead, silently run `git update-index --refresh` to
-	update the cached stat information for paths whose
-	contents in the work tree match the contents in the
-	index.  This option defaults to true.  Note that this
-	affects only 'git diff' Porcelain, and not lower level
-	'diff' commands such as 'git diff-files'.
-
-diff.dirstat::
-	A comma separated list of `--dirstat` parameters specifying the
-	default behavior of the `--dirstat` option to linkgit:git-diff[1]
-	and friends. The defaults can be overridden on the command line
-	(using `--dirstat=<param1,param2,...>`). The fallback defaults
-	(when not changed by `diff.dirstat`) are `changes,noncumulative,3`.
-	The following parameters are available:
-+
---
-`changes`;;
-	Compute the dirstat numbers by counting the lines that have been
-	removed from the source, or added to the destination. This ignores
-	the amount of pure code movements within a file.  In other words,
-	rearranging lines in a file is not counted as much as other changes.
-	This is the default behavior when no parameter is given.
-`lines`;;
-	Compute the dirstat numbers by doing the regular line-based diff
-	analysis, and summing the removed/added line counts. (For binary
-	files, count 64-byte chunks instead, since binary files have no
-	natural concept of lines). This is a more expensive `--dirstat`
-	behavior than the `changes` behavior, but it does count rearranged
-	lines within a file as much as other changes. The resulting output
-	is consistent with what you get from the other `--*stat` options.
-`files`;;
-	Compute the dirstat numbers by counting the number of files changed.
-	Each changed file counts equally in the dirstat analysis. This is
-	the computationally cheapest `--dirstat` behavior, since it does
-	not have to look at the file contents at all.
-`cumulative`;;
-	Count changes in a child directory for the parent directory as well.
-	Note that when using `cumulative`, the sum of the percentages
-	reported may exceed 100%. The default (non-cumulative) behavior can
-	be specified with the `noncumulative` parameter.
-<limit>;;
-	An integer parameter specifies a cut-off percent (3% by default).
-	Directories contributing less than this percentage of the changes
-	are not shown in the output.
---
-+
-Example: The following will count changed files, while ignoring
-directories with less than 10% of the total amount of changed files,
-and accumulating child directory counts in the parent directories:
-`files,10,cumulative`.
-
-diff.statGraphWidth::
-	Limit the width of the graph part in --stat output. If set, applies
-	to all commands generating --stat output except format-patch.
-
-diff.context::
-	Generate diffs with <n> lines of context instead of the default
-	of 3. This value is overridden by the -U option.
-
-diff.interHunkContext::
-	Show the context between diff hunks, up to the specified number
-	of lines, thereby fusing the hunks that are close to each other.
-	This value serves as the default for the `--inter-hunk-context`
-	command line option.
-
-diff.external::
-	If this config variable is set, diff generation is not
-	performed using the internal diff machinery, but using the
-	given command.  Can be overridden with the `GIT_EXTERNAL_DIFF'
-	environment variable.  The command is called with parameters
-	as described under "git Diffs" in linkgit:git[1].  Note: if
-	you want to use an external diff program only on a subset of
-	your files, you might want to use linkgit:gitattributes[5] instead.
-
-diff.ignoreSubmodules::
-	Sets the default value of --ignore-submodules. Note that this
-	affects only 'git diff' Porcelain, and not lower level 'diff'
-	commands such as 'git diff-files'. 'git checkout'
-	and 'git switch' also honor
-	this setting when reporting uncommitted changes. Setting it to
-	'all' disables the submodule summary normally shown by 'git commit'
-	and 'git status' when `status.submoduleSummary` is set unless it is
-	overridden by using the --ignore-submodules command-line option.
-	The 'git submodule' commands are not affected by this setting.
-
-diff.mnemonicPrefix::
-	If set, 'git diff' uses a prefix pair that is different from the
-	standard "a/" and "b/" depending on what is being compared.  When
-	this configuration is in effect, reverse diff output also swaps
-	the order of the prefixes:
-`git diff`;;
-	compares the (i)ndex and the (w)ork tree;
-`git diff HEAD`;;
-	 compares a (c)ommit and the (w)ork tree;
-`git diff --cached`;;
-	compares a (c)ommit and the (i)ndex;
-`git diff HEAD:file1 file2`;;
-	compares an (o)bject and a (w)ork tree entity;
-`git diff --no-index a b`;;
-	compares two non-git things (1) and (2).
-
-diff.noprefix::
-	If set, 'git diff' does not show any source or destination prefix.
-
-diff.relative::
-	If set to 'true', 'git diff' does not show changes outside of the directory
-	and show pathnames relative to the current directory.
-
-diff.orderFile::
-	File indicating how to order files within a diff.
-	See the '-O' option to linkgit:git-diff[1] for details.
-	If `diff.orderFile` is a relative pathname, it is treated as
-	relative to the top of the working tree.
-
-diff.renameLimit::
-	The number of files to consider when performing the copy/rename
-	detection; equivalent to the 'git diff' option `-l`. This setting
-	has no effect if rename detection is turned off.
-
-diff.renames::
-	Whether and how Git detects renames.  If set to "false",
-	rename detection is disabled. If set to "true", basic rename
-	detection is enabled.  If set to "copies" or "copy", Git will
-	detect copies, as well.  Defaults to true.  Note that this
-	affects only 'git diff' Porcelain like linkgit:git-diff[1] and
-	linkgit:git-log[1], and not lower level commands such as
-	linkgit:git-diff-files[1].
-
-diff.suppressBlankEmpty::
-	A boolean to inhibit the standard behavior of printing a space
-	before each empty output line. Defaults to false.
-
-diff.submodule::
-	Specify the format in which differences in submodules are
-	shown.  The "short" format just shows the names of the commits
-	at the beginning and end of the range. The "log" format lists
-	the commits in the range like linkgit:git-submodule[1] `summary`
-	does. The "diff" format shows an inline diff of the changed
-	contents of the submodule. Defaults to "short".
-
-diff.wordRegex::
-	A POSIX Extended Regular Expression used to determine what is a "word"
-	when performing word-by-word difference calculations.  Character
-	sequences that match the regular expression are "words", all other
-	characters are *ignorable* whitespace.
-
-diff.<driver>.command::
-	The custom diff driver command.  See linkgit:gitattributes[5]
-	for details.
-
-diff.<driver>.xfuncname::
-	The regular expression that the diff driver should use to
-	recognize the hunk header.  A built-in pattern may also be used.
-	See linkgit:gitattributes[5] for details.
-
-diff.<driver>.binary::
-	Set this option to true to make the diff driver treat files as
-	binary.  See linkgit:gitattributes[5] for details.
-
-diff.<driver>.textconv::
-	The command that the diff driver should call to generate the
-	text-converted version of a file.  The result of the
-	conversion is used to generate a human-readable diff.  See
-	linkgit:gitattributes[5] for details.
-
-diff.<driver>.wordRegex::
-	The regular expression that the diff driver should use to
-	split words in a line.  See linkgit:gitattributes[5] for
-	details.
-
-diff.<driver>.cachetextconv::
-	Set this option to true to make the diff driver cache the text
-	conversion outputs.  See linkgit:gitattributes[5] for details.
-
-diff.tool::
-	Controls which diff tool is used by linkgit:git-difftool[1].
-	This variable overrides the value configured in `merge.tool`.
-	The list below shows the valid built-in values.
-	Any other value is treated as a custom diff tool and requires
-	that a corresponding difftool.<tool>.cmd variable is defined.
-
-diff.guitool::
-	Controls which diff tool is used by linkgit:git-difftool[1] when
-	the -g/--gui flag is specified. This variable overrides the value
-	configured in `merge.guitool`. The list below shows the valid
-	built-in values. Any other value is treated as a custom diff tool
-	and requires that a corresponding difftool.<guitool>.cmd variable
-	is defined.
-
-include::../mergetools-diff.txt[]
-
-diff.indentHeuristic::
-	Set this option to `false` to disable the default heuristics
-	that shift diff hunk boundaries to make patches easier to read.
-
-diff.algorithm::
-	Choose a diff algorithm.  The variants are as follows:
-+
---
-`default`, `myers`;;
-	The basic greedy diff algorithm. Currently, this is the default.
-`minimal`;;
-	Spend extra time to make sure the smallest possible diff is
-	produced.
-`patience`;;
-	Use "patience diff" algorithm when generating patches.
-`histogram`;;
-	This algorithm extends the patience algorithm to "support
-	low-occurrence common elements".
---
-+
-
-diff.wsErrorHighlight::
-	Highlight whitespace errors in the `context`, `old` or `new`
-	lines of the diff.  Multiple values are separated by comma,
-	`none` resets previous values, `default` reset the list to
-	`new` and `all` is a shorthand for `old,new,context`.  The
-	whitespace errors are colored with `color.diff.whitespace`.
-	The command line option `--ws-error-highlight=<kind>`
-	overrides this setting.
-
-diff.colorMoved::
-	If set to either a valid `<mode>` or a true value, moved lines
-	in a diff are colored differently, for details of valid modes
-	see '--color-moved' in linkgit:git-diff[1]. If simply set to
-	true the default color mode will be used. When set to false,
-	moved lines are not colored.
-
-diff.colorMovedWS::
-	When moved lines are colored using e.g. the `diff.colorMoved` setting,
-	this option controls the `<mode>` how spaces are treated
-	for details of valid modes see '--color-moved-ws' in linkgit:git-diff[1].
