In anticipation of combining the logic from the commit-graph and
multi-pack-index file formats, create a new chunk-format API. Use a
'struct chunkfile' pointer to keep track of data that has been
registered for writes. This struct is anonymous outside of
chunk-format.c to ensure no user attempts to interfere with the data.
The next change will use this API in commit-graph.c, but the general
approach is:
1. initialize the chunkfile with init_chunkfile(f).
2. add chunks in the intended writing order with add_chunk().
3. write any header information to the hashfile f.
4. write the chunkfile data using write_chunkfile().
5. free the chunkfile struct using free_chunkfile().

In the implementation of "git difftool", there is a case where the
user wants to start viewing the diffs at a specific path and
continue on to the rest, optionally wrapping around to the
beginning. Since it is somewhat cumbersome to implement such a
feature as a post-processing step of "git diff" output, let's
support it internally with two new options.
- "git diff --rotate-to=C", when the resulting patch would show
paths A B C D E without the option, would "rotate" the paths to
shows patch to C D E A B instead. It is an error when there is
no patch for C is shown.
- "git diff --skip-to=C" would instead "skip" the paths before C,
and shows patch to C D E. Again, it is an error when there is no
patch for C is shown.
- "git log [-p]" also accepts these two options, but it is not an
error if there is no change to the specified path. Instead, the
set of output paths are rotated or skipped to the specified path
or the first path that sorts after the specified path.

Improve the support for invalid UTF-8 haystacks given a non-ASCII
needle when using the PCREv2 backend.
This is a more complete fix for a bug I started to fix in
870eea8166 (grep: do not enter PCRE2_UTF mode on fixed matching,
2019-07-26), now that PCREv2 has the PCRE2_MATCH_INVALID_UTF mode we
can make use of it.
This fixes the sort of case described in 8a5999838e (grep: stess test
PCRE v2 on invalid UTF-8 data, 2019-07-26), i.e.:
- The subject string is non-ASCII (e.g. "ævar")
- We're under a is_utf8_locale(), e.g. "en_US.UTF-8", not "C"
- We are using --ignore-case, or we're a non-fixed pattern
If those conditions were satisfied and we matched found non-valid
UTF-8 data PCREv2 might bark on it, in practice this only happened
under the JIT backend (turned on by default on most platforms).
Ultimately this fixes a "regression" in b65abcafc7 ("grep: use PCRE v2
for optimized fixed-string search", 2019-07-01), I'm putting that in
scare-quotes because before then we wouldn't properly support these
complex case-folding, locale etc. cases either, it just broke in
different ways.
There was a bug related to this the PCRE2_NO_START_OPTIMIZE flag fixed
in PCREv2 10.36. It can be worked around by setting the
PCRE2_NO_START_OPTIMIZE flag. Let's do that in those cases, and add
tests for the bug.

Remove support for using version 1 of the PCRE library. Its use has
been discouraged by upstream for a long time, and it's in a
bugfix-only state.
Anyone who was relying on v1 in particular got a nudge to move to v2
in e6c531b808 (Makefile: make USE_LIBPCRE=YesPlease mean v2, not v1,

With this the LIBPCRE2 test prerequisites is redundant to PCRE. But
I'm keeping it for self-documentation purposes, and to avoid conflict
with other in-flight PCRE patches.
I'm also not changing all of our own "pcre2" names to "pcre", i.e. the
inverse of 6d4b5747f0 (grep: change internal *pcre* variable &
function names to be *pcre1*, 2017-05-25). I don't see the point, and

it be necessary to remove this directory in the 'clean' target, since

We normally get the list of builtin commands by expanding BUILTIN_OBJS.
But for commands which are embedded inside another's source file (e.g.,
cmd_show() in builtin/log.c), the Makefile needs to be told explicitly
about them.
Since cmd_maintenance() is inside buitin/gc.c, it should be listed
explicitly in the BUILT_INS list in the Makefile. Not doing so isn't
_too_ tragic, as it simply means we will not make a git-maintenance
symlink in libexec/git-core. Since we encourage people to use the "git
foo" form, even in scripts which have put libexec into their PATH,
nobody seems to have noticed.

The previous two commits removed the last use of a function in this

Add a new test-tool command named 'fast-rebase', which is a
super-slimmed down and nowhere near as capable version of 'git rebase'.
'test-tool fast-rebase' is not currently planned for usage in the
testsuite, but is here for two purposes:
1) Demonstrate the desired API of merge-ort. In particular,
fast-rebase takes advantage of the separation of the merging
operation from the updating of the index and working tree, to
allow it to pick N commits, but only update the index and working
tree once at the end. Look for the calls to
merge_incore_nonrecursive() and merge_switch_to_result().
2) Provide a convenient benchmark that isn't polluted by the heavy
disk writing and forking of unnecessary processes that comes from
sequencer.c and merge-recursive.c. fast-rebase is not meant to
replace sequencer.c, just give ideas on how sequencer.c can be
changed. Updating sequencer.c with these goals is probably a
large amount of work; writing a simple targeted command with
no documentation, less-than-useful help messages, numerous
limitations in terms of flags it can accept and situations it can
handle, and which is flagged off from users is a much easier
interim step.

There are a few differences between the new API in merge-ort and the old
API in merge-recursive. While the new API is more flexible, it might
feel like more work at times than the old API. merge-ort-wrappers
creates two convenience wrappers taking the exact same arguments as the
old merge_trees() and merge_recursive() functions and implements them
via the new API. This makes converting existing callsites easier, and
serves to highlight some of the differences in the API.

This is the beginning of a new merge strategy. While there are some API
differences, and the implementation has some differences in behavior, it
is essentially meant as an eventual drop-in replacement for
merge-recursive.c. However, it is being built to exist side-by-side
with merge-recursive so that we have plenty of time to find out how
those differences pan out in the real world while people can still fall
back to merge-recursive. (Also, I intend to avoid modifying
merge-recursive during this process, to keep it stable.)
The primary difference noticable here is that the updating of the
working tree and index is not done simultaneously with the merge
algorithm, but is a separate post-processing step. The new API is
designed so that one can do repeated merges (e.g. during a rebase or
cherry-pick) and only update the index and working tree one time at the
end instead of updating it with every intermediate result. Also, one
can perform a merge between two branches, neither of which match the
index or the working tree, without clobbering the index or working tree.
The next three commits will demonstrate various uses of this new API.

We set "use warnings" in most of our perl code to catch problems. But as
the name implies, warnings just emit a message to stderr and don't
otherwise affect the program. So our tests are quite likely to miss that
warnings are being spewed, as most of them do not look at stderr.
We could ask perl to make all warnings fatal, but this is likely
annoying for non-developers, who would rather have a running program
with a warning than something that refuses to work at all.
So instead, let's teach the perl code to respect an environment variable
(GIT_PERL_FATAL_WARNINGS) to increase the severity of the warnings. This
can be set for day-to-day running if people want to be really pedantic,
but the primary use is to trigger it within the test suite.
We could also trigger that for every test run, but likewise even the
tests failing may be annoying to distro builders, etc (just as -Werror
would be for compiling C code). So we'll tie it to a special test-mode
variable (GIT_TEST_PERL_FATAL_WARNINGS) that can be set in the
environment or as a Makefile knob, and we'll automatically turn the knob
when DEVELOPER=1 is set. That should give developers and CI the more
careful view without disrupting normal users or packagers.
Note that the mapping from the GIT_TEST_* form to the GIT_* form in
test-lib.sh is necessary even if they had the same name: the perl
scripts need it to be normalized to a perl truth value, and we also have
to make sure it's exported (we might have gotten it from the
environment, but we might also have gotten it from GIT-BUILD-OPTIONS
directly).

specifically excluded the three commands `receive-pack`,
`upload-archive` and `upload-pack`, though: these commands are expected
to be present in the `PATH` in their dashed form on the server side of
any fetch/push.
However, due to an oversight by myself, even if those commands were
still hard-linked, they were not installed into `bin/`.
