quote_c_style() and its friend quote_two_c_style() both take an
optional "please omit the double quotes around the quoted body"
parameter. Turn it into a flag word, assign one bit out of it,
and call it CQUOTE_NODQ bit.

This table is used to see if each byte needs quoting when responding
to a request to C-quote the string, not quoting with single-quote in
the shell style. Similarly, sq_must_quote() is fed each byte from
the string being C-quoted.

Tracked paths with SP in them were cquoted in "git status --short"
output, but untracked, ignored, and unmerged paths weren't.
The test was stolen from a patch to fix output for the 'untracked'
paths by brian m. carlson, with similar tests added for 'ignored'
ones.

The implementation we moved from wt-status to enclose a pathname
that has a SP in it inside a dq-pair is a bit convoluted. It lets
quote_c_style_counted() do its escaping and then
(1) if the input string got escaped, which is checked by seeing if
the result begins with a double-quote, declare that we are
done. If there wasn't any SP in the input, that is OK, and if
there was, the result is quoted already so it is OK, too.
(2) if the input string did not get escaped, and the result has SP
in it, enclose the whole thing in a dq-pair ourselves.
Instead we can scan the path upfront to see if the input has SP in
it. If so, we tell quote_c_style_counted() not to enclose its
output in a dq-pair, and we add a dq-pair ourselves. Whether the
input had bytes that quote_c_style_counted() uses backslash quoting,
this would give us a desired quoted string. If the input does not
have SP in it, we just let quote_c_style_counted() do its thing as
usual, which would enclose the result in a dq-pair only when needed.

Some code in wt-status.c special case a path with SP in it, which
usually does not have to be c-quoted, and ensure that such a path
does get quoted. Move the logic to quote_path() and give it a bit
in the flags word, QUOTE_PATH_QUOTE_SP.
No behaviour change intended.

The quote_path() function computes a path (relative to its base
directory) and c-quotes the result if necessary. Teach it to take a
flags parameter to allow its behaviour to be enriched later.

"git status" has trouble showing where it came from by interpreting
reflog entries that recordcertain events, e.g. "checkout @{u}", and
gives a hard/fatal error. Even though it inherently is impossible
to give a correct answer because the reflog entries lose some
information (e.g. "@{u}" does not record what branch the user was
on hence which branch 'the upstream' needs to be computed, and even
if the record were available, the relationship between branches may
have changed), at least hide the error to allow "status" show its
output.

The maintainer's dist rules are used to produce distribution
tarballs. They use "$(TAR) cf" and "$(TAR) rf" to produce archives
out of a freshly created local installation area, which means that
the built product can be affected by maintainer's umask and other
local environment.
Implementations of "tar" have ways (implementation specific,
unfortunately) to force permission bits and other stuff to allow the
user to hide these effects coming from the local environment. Teach
our Makefile to allow the maintainer to tweak the invocation of the
$(TAR) commands by setting TAR_DIST_EXTRA_OPTS.

Currently, when index-pack resolves deltas, it does not split up delta
trees into threads: each delta base root (an object that is not a
REF_DELTA or OFS_DELTA) can go into its own thread, but all deltas on
that root (direct or indirect) are processed in the same thread.
This is a problem when a repository contains a large text file (thus,
delta-able) that is modified many times - delta resolution time during
fetching is dominated by processing the deltas corresponding to that
text file.
This patch contains a solution to that. When cloning using
git -c core.deltabasecachelimit=1g clone \
https://fuchsia.googlesource.com/third_party/vulkan-cts
on my laptop, clone time improved from 3m2s to 2m5s (using 3 threads,
which is the default).
The solution is to have a global work stack. This stack contains delta
bases (objects, whether appearing directly in the packfile or generated
by delta resolution, that themselves have delta children) that need to
be processed; whenever a thread needs work, it peeks at the top of the
stack and processes its next unprocessed child. If a thread finds the
stack empty, it will look for more delta base roots to push on the stack
instead.
The main weakness of having a global work stack is that more time is
spent in the mutex, but profiling has shown that most time is spent in
the resolution of the deltas themselves, so this shouldn't be an issue
in practice. In any case, experimentation (as described in the clone
command above) shows that this patch is a net improvement.

REF_LOG_ONLY is used in the transaction preparation: if a symref is involved in
a transaction, the referent of the symref should be updated, and the symref
itself should only be updated in the reflog.
Other ref backends will need to duplicate this logic too, so move it to a
central place.

The "refuse --edit-description on unborn branch for now" test in t3200
switches to an orphan branch, causing subsequent git commands
referencing HEAD to fail. Avoid this side-effect by switching back to
master after the test finishes.
This has gone undetected, as the next affected test expects failure -
but it currently fails for the wrong reason.
Verbose output of the next test referencing HEAD,
"--merged is incompatible with --no-merged":
fatal: malformed object name HEAD
Which this commit corrects to:

When formatting a patch series over `origin..HEAD`, one would expect
that range to be used as the current-series-range when computing a
range-diff between the previous and current versions of a patch series.
However, infer_range_diff_ranges() ignores `origin..HEAD` when
--range-diff=<prev> specifies a single revision rather than a range, and
instead unexpectedly computes the current-series-range based upon
<prev>. Address this anomaly by unconditionally using `origin..HEAD` as
the current-series-range regardless of <prev> as long as `origin` is
known, and only fall back to basing current-series-range on <prev> when
`origin` is not known.

To compute and show an interdiff, show_interdiff() needs only the two
OID's to compare and a diffopts, yet it expects callers to supply an
entire rev_info. The demand for rev_info is not only overkill, but also
places unnecessary burden on potential future callers which might not
otherwise have a rev_info at hand. Address this by tightening its
signature to require only the items it needs instead of a full rev_info.

show_interdiff() is a relatively small function and not likely to grow
larger or more complicated. Rather than dedicating an entire source file
to it, relocate it to diff-lib.c which houses other "take two things and
compare them" functions meant to be re-used but not so low-level as to
reside in the core diff implementation.

We have had parallel implementations of "add -i/-p" since 2.25 and
have been using them from various codepaths since 2.26 days, but
never made the built-in version the default.
We have found and fixed a handful of corner case bugs in the
built-in version, and it may be a good time to start switching over
the user base from the scripted version to the built-in version.
Let's enable the built-in version for those who opt into the
feature.experimental guinea-pig program to give wider exposure.
