"git stash" rewritten in C.
* ps/stash-in-c: (28 commits)
tests: add a special setup where stash.useBuiltin is off
stash: optionally use the scripted version again
stash: add back the original, scripted `git stash`
stash: convert `stash--helper.c` into `stash.c`
stash: replace all `write-tree` child processes with API calls
stash: optimize `get_untracked_files()` and `check_changes()`
stash: convert save to builtin
stash: make push -q quiet
stash: convert push to builtin
stash: convert create to builtin
stash: convert store to builtin
stash: convert show to builtin
stash: convert list to builtin
stash: convert pop to builtin
stash: convert branch to builtin
stash: convert drop and clear to builtin
stash: convert apply to builtin
stash: mention options in `show` synopsis
stash: add tests for `git stash show` config
stash: rename test cases to be more descriptive

this feature by setting the GIT_TEST_CHAIN_LINT environment
variable to "1" or "0", respectively.
+--stress::
+ Run the test script repeatedly in multiple parallel jobs until
+ one of them fails. Useful for reproducing rare failures in
+ flaky tests. The number of parallel jobs is, in order of
+ precedence: the value of the GIT_TEST_STRESS_LOAD
+ environment variable, or twice the number of available
+ processors (as shown by the 'getconf' utility), or 8.
+ Implies `--verbose -x --immediate` to get the most information
+ about the failure. Note that the verbose output of each test
+ job is saved to 't/test-results/$TEST_NAME.stress-<nr>.out',
+ and only the output of the failed test job is shown on the
+ terminal. The names of the trash directories get a
+ '.stress-<nr>' suffix, and the trash directory of the failed
+ test job is renamed to end with a '.stress-failed' suffix.
+
+--stress-jobs=<N>::
+ Override the number of parallel jobs. Implies `--stress`.
+
+--stress-limit=<N>::
+ When combined with --stress run the test script repeatedly
+ this many times in each of the parallel jobs or until one of
+ them fails, whichever comes first. Implies `--stress`.

You can also set the GIT_TEST_INSTALLED environment variable to
the bindir of an existing git installation to test that installation.
You still need to have built this git sandbox, from which various
GIT_TEST_SPLIT_INDEX=<boolean> forces split-index mode on the whole
test suite. Accept any boolean values that are accepted by git-config.
+GIT_TEST_PROTOCOL_VERSION=<n>, when set, overrides the
+'protocol.version' setting to n if it is less than n.
+
GIT_TEST_FULL_IN_PACK_ARRAY=<boolean> exercises the uncommon
pack-objects code path where there are more than 1024 packs even if
the actual number of packs in repository is below this limit. Accept
for the index version specified. Can be set to any valid version
(currently 2, 3, or 4).
+GIT_TEST_PACK_SPARSE=<boolean> if enabled will default the pack-objects
+builtin to use the sparse object walk. This can still be overridden by
+the --no-sparse command-line argument.
+
GIT_TEST_PRELOAD_INDEX=<boolean> exercises the preload-index code path
by overriding the minimum number of cache entries required per thread.
-GIT_TEST_REBASE_USE_BUILTIN=<boolean>, when false, disables the
-builtin version of git-rebase. See 'rebase.useBuiltin' in
-git-config(1).
-
+ GIT_TEST_STASH_USE_BUILTIN=<boolean>, when false, disables the
+ built-in version of git-stash. See 'stash.useBuiltin' in

+
GIT_TEST_INDEX_THREADS=<n> enables exercising the multi-threaded loading
of the index for the whole test suite by bypassing the default number of
cache entries and thread minimums. Setting this to 1 will make the
index to be written after every 'git repack' command, and overrides the
'core.multiPackIndex' setting to true.

Naming Tests
------------
- Creates an empty test directory with an empty .git/objects database
and chdir(2) into it. This directory is 't/trash
directory.$test_name_without_dotsh', with t/ subject to change by
- the --root option documented above.
+ the --root option documented above, and a '.stress-<N>' suffix
+ appended by the --stress option.
- Defines standard test helper functions for your scripts to
use. These functions are designed to make all scripts behave
test_oid_init or test_oid_cache. Providing an unknown key is an
error.
+ - yes [<string>]
+
+ This is often seen in modern UNIX but some platforms lack it, so
+ the test harness overrides the platform implementation with a
+ more limited one. Use this only when feeding a handful lines of
+ output to the downstream---unlike the real version, it generates
+ only up to 99 lines.
