Add optional trace logging to allow us to better compare performance of
various fsmonitor providers and compare results with non-fsmonitor runs.
Currently, this includes Trace2 logging, but may be extended to include
other trace targets, such as GIT_TRACE_FSMONITOR if desired.
Using this logging helped me explain an odd behavior on MacOS where the
kernel was dropping events and causing the hook to Watchman to timeout.

Shutdown Watchman after the Watchman-based tests and before the block of
"no fsmonitor" tests.
This helps ensure that Watchman cannot affect the test results for the
other.

Only use the final portion of the test trash directory file name
when verifying that Watchman was started.
On Windows and under the SDK, $GIT_WORKTREE is a cygwin-style
path with forward slashes and a "/c/" drive name. However
`watchman watch-list` reports a proper Windows-style pathname
with drive letters and backslashes. This causes the grep to
fail. Since we don't really care about the full pathname (and
we really don't want to bother with normalizaing them), just see
if the test-name portion of the path is found.

Convert the test to use a more portable method to update the mtime on a
large number of files under version control.
The Mac version of xargs does not support the "-d" option.
Likewise, the "-0" and "--null" options are not portable.
Furthermore, use `test-tool chmtime` rather than `touch` to update the
mtime to ensure that it is actually updated (especially on file systems
with only whole second resolution).

The logic added to check for negative pathspec match by c0192df630
(refspec: add support for negative refspecs, 2020-09-30) looks at
refspec->src assuming it is never NULL, however when
remote.origin.push is set to ":", then refspec->src is NULL,
causing a segfault within strcmp.
Tell git to handle matching refspec by adding the needle to the
set of positively matched refspecs, since matching ":" refspecs
match anything as src.
Add test for matching refspec pushes fetch-negative-refspec
both individually and in combination with a negative refspec.

When we insert our "BEGIN" and "END" markers into the cron table, it's
so that a Git version from many years into the future would be able to
identify this region in the cron table. Let's add a test to make sure
that these markers don't ever change.

On `git maintenance start`, we add a few entries to the user's cron
table. We wrap our entries using two magic markers, "# BEGIN GIT
MAINTENANCE SCHEDULE" and "# END GIT MAINTENANCE SCHEDULE". At a later
`git maintenance stop`, we will go through the table and remove these
lines. Or rather, we will remove the "BEGIN" marker, the "END" marker
and everything between them.
Alas, we have a bug in how we detect the "END" marker: we don't. As we
loop through all the lines of the crontab, if we are in the "old
region", i.e., the region we're aiming to remove, we make an early
`continue` and don't get as far as checking for the "END" marker. Thus,
once we've seen our "BEGIN", we remove everything until the end of the
file.
Rewrite the logic for identifying these markers. There are four cases
that are mutually exclusive: The current line starts a region or it ends
it, or it's firmly within the region, or it's outside of it (and should
be printed).

This fixes a segmentation fault.
The bug is caused by dereferencing `new_branch_info->commit` when it is
`NULL`, which is the case when the tree-ish argument is actually a tree,
not a commit-ish. This was introduced in 5602b500c3c (builtin/checkout:
fix `git checkout -p HEAD...` bug, 2020-10-07), where we tried to ensure
that the special tree-ish `HEAD...` is handled correctly.

Command `git pack-redundant --all` will crash if there is only one
packfile in the repository. This is because, if there is only one
packfile in local_packs, `cmp_local_packs` will do nothing and will

whitespace differences results in no changes shown, if ignoring

test_perf() runs each test in its own subshell which makes it difficult
to persist variables between tests. test_export() addresses this
shortcoming by grabbing the values of specified variables after a test
runs but before the subshell exits, and writes those values to a file
which is loaded into the environment of subsequent tests.
To grab the values to be persisted, test_export() pipes the output of
the shell's builtin `set` command through `sed` which plucks them out
using a regular expression along the lines of `s/^(var1|var2)/.../p`.
Unfortunately, though, this use of alternation is not portable. For
instance, BSD-lineage `sed` (including macOS `sed`) does not support it
in the default "basic regular expression" mode (BRE). It may be possible
to enable "extended regular expression" mode (ERE) in some cases with
`sed -E`, however, `-E` is neither portable nor part of POSIX.
Fortunately, alternation is unnecessary in this case and can easily be
avoided, so replace it with a series of simple expressions such as
`s/^var1/.../p;s/^var2/.../p`.
While at it, tighten the expressions so they match the variable names
exactly rather than matching prefixes (i.e. use `s/^var1=/.../p`).
If the requirements of test_export() become more complex in the future,
then an alternative would be to replace `sed` with `perl` which supports
alternation on all platforms, however, the simple elimination of
alternation via multiple `sed` expressions suffices for the present.

To give ample warning for users wishing to override Git's the fall-back
for an unconfigured `init.defaultBranch` (in case we decide to change it
in a future Git version), let's introduce some advice that is shown upon
`git init` when that value is not set.
Note: two test cases in Git's test suite want to verify that the
`stderr` output of `git init` is empty. It is now necessary to suppress
the advice, we now do that via the `init.defaultBranch` setting. While
not strictly necessary, we also set this to `false` in
`test_create_repo()`.
