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.

-Git v2.10.1 Release Notes
-=========================
-
-Fixes since v2.10
------------------
-
- * Clarify various ways to specify the "revision ranges" in the
-   documentation.
-
- * "diff-highlight" script (in contrib/) learned to work better with
-   "git log -p --graph" output.
-
- * The test framework left the number of tests and success/failure
-   count in the t/test-results directory, keyed by the name of the
-   test script plus the process ID.  The latter however turned out not
-   to serve any useful purpose.  The process ID part of the filename
-   has been removed.
-
- * Having a submodule whose ".git" repository is somehow corrupt
-   caused a few commands that recurse into submodules loop forever.
-
- * "git symbolic-ref -d HEAD" happily removes the symbolic ref, but
-   the resulting repository becomes an invalid one.  Teach the command
-   to forbid removal of HEAD.
-
- * A test spawned a short-lived background process, which sometimes
-   prevented the test directory from getting removed at the end of the
-   script on some platforms.
-
- * Update a few tests that used to use GIT_CURL_VERBOSE to use the
-   newer GIT_TRACE_CURL.
-
- * Update Japanese translation for "git-gui".
-
- * "git fetch http::/site/path" did not die correctly and segfaulted
-   instead.
-
- * "git commit-tree" stopped reading commit.gpgsign configuration
-   variable that was meant for Porcelain "git commit" in Git 2.9; we
-   forgot to update "git gui" to look at the configuration to match
-   this change.
-
- * "git log --cherry-pick" used to include merge commits as candidates
-   to be matched up with other commits, resulting a lot of wasted time.
-   The patch-id generation logic has been updated to ignore merges to
-   avoid the wastage.
-
- * The http transport (with curl-multi option, which is the default
-   these days) failed to remove curl-easy handle from a curlm session,
-   which led to unnecessary API failures.
-
- * "git diff -W" output needs to extend the context backward to
-   include the header line of the current function and also forward to
-   include the body of the entire current function up to the header
-   line of the next one.  This process may have to merge to adjacent
-   hunks, but the code forgot to do so in some cases.
-
- * Performance tests done via "t/perf" did not use the same set of
-   build configuration if the user relied on autoconf generated
-   configuration.
-
- * "git format-patch --base=..." feature that was recently added
-   showed the base commit information after "-- " e-mail signature
-   line, which turned out to be inconvenient.  The base information
-   has been moved above the signature line.
-
- * Even when "git pull --rebase=preserve" (and the underlying "git
-   rebase --preserve") can complete without creating any new commit
-   (i.e. fast-forwards), it still insisted on having a usable ident
-   information (read: user.email is set correctly), which was less
-   than nice.  As the underlying commands used inside "git rebase"
-   would fail with a more meaningful error message and advice text
-   when the bogus ident matters, this extra check was removed.
-
- * "git gc --aggressive" used to limit the delta-chain length to 250,
-   which is way too deep for gaining additional space savings and is
-   detrimental for runtime performance.  The limit has been reduced to
-   50.
-
- * Documentation for individual configuration variables to control use
-   of color (like `color.grep`) said that their default value is
-   'false', instead of saying their default is taken from `color.ui`.
-   When we updated the default value for color.ui from 'false' to
-   'auto' quite a while ago, all of them broke.  This has been
-   corrected.
-
- * A shell script example in check-ref-format documentation has been
-   fixed.
-
- * "git checkout <word>" does not follow the usual disambiguation
-   rules when the <word> can be both a rev and a path, to allow
-   checking out a branch 'foo' in a project that happens to have a
-   file 'foo' in the working tree without having to disambiguate.
-   This was poorly documented and the check was incorrect when the
-   command was run from a subdirectory.
-
- * Some codepaths in "git diff" used regexec(3) on a buffer that was
-   mmap(2)ed, which may not have a terminating NUL, leading to a read
-   beyond the end of the mapped region.  This was fixed by introducing
-   a regexec_buf() helper that takes a <ptr,len> pair with REG_STARTEND
-   extension.
-
- * The procedure to build Git on Mac OS X for Travis CI hardcoded the
-   internal directory structure we assumed HomeBrew uses, which was a
-   no-no.  The procedure has been updated to ask HomeBrew things we
-   need to know to fix this.
-
- * When "git rebase -i" is given a broken instruction, it told the
-   user to fix it with "--edit-todo", but didn't say what the step
-   after that was (i.e. "--continue").
-
- * "git add --chmod=+x" added recently lacked documentation, which has
-   been corrected.
-
- * "git add --chmod=+x <pathspec>" added recently only toggled the
-   executable bit for paths that are either new or modified. This has
-   been corrected to flip the executable bit for all paths that match
-   the given pathspec.
-
- * "git pack-objects --include-tag" was taught that when we know that
-   we are sending an object C, we want a tag B that directly points at
-   C but also a tag A that points at the tag B.  We used to miss the
-   intermediate tag B in some cases.
-
- * Documentation around tools to import from CVS was fairly outdated.
-
- * In the codepath that comes up with the hostname to be used in an
-   e-mail when the user didn't tell us, we looked at ai_canonname
-   field in struct addrinfo without making sure it is not NULL first.
-
-Also contains minor documentation updates and code clean-ups.
