The gitattributes documentation mentions that either the clean cmd or
the smudge cmd can be left unspecified in a filter definition. However,
when the filter is marked as 'required', the absence of any one of these
two should be treated as an error. Git already fails under these
circumstances, but not always in a pleasant way: omitting a clean cmd in
a required filter triggers an assertion error which leaves the user with
a quite verbose message:
git: convert.c:1459: convert_to_git_filter_fd: Assertion "ca.drv->clean || ca.drv->process" failed.
This assertion is not really necessary, as the apply_filter() call below
it already performs the same check. And when this condition is not met,
the function returns 0, making the caller die() with a much nicer
message. (Also note that die()-ing here is the right behavior as
`would_convert_to_git_filter_fd() == true` is a precondition to use
convert_to_git_filter_fd(), and the former is only true when the filter
is required.) So remove the assertion and add two regression tests to
make sure that git fails nicely when either the smudge or clean command
is missing on a required filter.

We have two established generation number versions:
1: topological levels
2: corrected commit dates
The corrected commit dates are enabled by default, but they also write
extra data in the GDAT and GDOV chunks. Services that host Git data
might want to have more control over when this feature rolls out than
just updating the Git binaries.
Add a new "commitGraph.generationVersion" config option that specifies
the intended generation number version. If this value is less than 2,
then the GDAT chunk is never written _or read_ from an existing file.
This can replace our use of the GIT_TEST_COMMIT_GRAPH_NO_GDAT
environment variable in the test suite. Remove it.

When a remote is renamed don't change the canonical "*.pushRemote"

While we're at it let's also test that we handle the "*.pushDefault"

Change "git remote add" so that it adds a *.tagOpt key, and not the
lower-cased *.tagopt on "git remote add --no-tags", just as "git clone
--no-tags" would do.
This doesn't matter for anything that reads the config. It's just
prettier if we write config keys in their documented camelCase form to
user-readable config files.
When I added support for "clone -no-tags" in 0dab2468ee (clone: add a
--no-tags option to clone without tags, 2017-04-26) I made it use
the *.tagOpt form, but the older "git remote add" added in
111fb85865 (remote add: add a --[no-]tags option, 2010-04-20) has
been using *.tagopt all this time.
It's easy enough to add a test for this, so let's do that. We can't
use "git config -l" there, because it'll normalize the keys to their
lower-cased form. Let's add the test for "git clone" too for good
measure, not just to the "git remote" codepath we're fixing.

Writing an index 8K at a time invokes the OS filesystem and caching code
very frequently, introducing noticeable overhead while writing large
indexes. When experimenting with different write buffer sizes on Windows
writing the Windows OS repo index (260MB), most of the benefit came by
bumping the index write buffer size to 64K. I picked 128K to ensure that
we're past the knee of the curve.
With this change, the time under do_write_index for an index with 3M
files goes from ~1.02s to ~0.72s.

If `add` encounters an error while applying the --chmod changes, it
prints a message to stderr, but exits with a success code. This might
have been an oversight, as the command does exit with a non-zero code in
other situations where it cannot (or refuses to) update all of the
requested paths (e.g. when some of the given paths are ignored). So make
the exit behavior more consistent by also propagating --chmod errors to
the exit status.
Note: the test "all statuses changed in folder if . is given" uses paths
added by previous test cases, some of which might be symbolic links.
Because `git add --chmod` will now fail with such paths, this test would
depend on whether all the previous tests were executed, or only some
of them. Avoid that by running the test on a fresh repo with only
regular files.

Use FLEX_ALLOC_STR() to allocate the `struct untracked_cache_dir`
for the root directory. Get rid of unsafe code that might fail to
initialize the `name` field (if FLEX_ARRAY is not 1). This will
make it clear that we intend to have a structure with an empty
string following it.
A problem was observed on Windows where the length of the memset() was
too short, so the first byte of the name field was not zeroed. This
resulted in the name field having garbage from a previous use of that
area of memory.
The record for the root directory was then written to the untracked-cache
extension in the index. This garbage would then be visible to future
commands when they reloaded the untracked-cache extension.
Since the directory record for the root directory had garbage in the
`name` field, the `t/helper/test-tool dump-untracked-cache` tool
printed this garbage as the path prefix (rather than '/') for each
directory in the untracked cache as it recursed.

When writing a commit-graph, a progress meter is shown which indicates
the number of pieces of data to write (one per commit in each chunk).
In 47410aa837 (commit-graph: use chunk-format write API, 2021-02-18),
the number of chunks became tracked by the new chunk-format API. But a
stray local variable was left behind from when write_commit_graph_file()
used to keep track of the same.
Since this was no longer updated after 47410aa837, the progress meter
appeared broken:
$ git commit-graph write --reachable
Expanding reachable commits in commit graph: 837569, done.
Writing out commit graph in 3 passes: 166% (4187845/2512707), done.
Drop the local variable and rely instead on the chunk-format API to tell
us the correct number of chunks.

When we added a syntax sugar "git push remote --delete <ref>" to
"git push" as a synonym to the canonical "git push remote :<ref>"
syntax at f517f1f2 (builtin-push: add --delete as syntactic sugar
for :foo, 2009-12-30), we weren't careful enough to make sure that
<ref> is not empty.
Blindly rewriting "--delete <ref>" to ":<ref>" means that an empty
string <ref> results in refspec ":", which is the syntax to ask for
"matching" push that does not delete anything.
Worse yet, if there were matching refs that can be fast-forwarded,
they would have been published prematurely, even if the user feels
that they are not ready yet to be pushed out, which would be a real
disaster.

This adds yet another vimdiff/gvimdiff variant and presents conflicts as
a two-way diff between 'LOCAL' and 'REMOTE'. 'MERGED' is not opened
which deviates from the norm so usage text is echoed as a Vim message on
startup that instructs the user with how to proceed and how to abort.
Vimdiff is well-suited to two-way diffs so this is an option for a more
simple, more streamlined conflict resolution. For example: it is
difficult to communicate differences across more than two files using
only syntax highlighting; default vimdiff commands to get and put
changes between buffers do not need the user to manually specify
a source or destination buffer when only using two buffers.
Like other merge tools that directly compare 'LOCAL' with 'REMOTE', this
tool will benefit when paired with the new `mergetool.hideResolved`
setting.
