Upstream Git has introduced support for the Meson build system.
Introduce support for Meson into gitk, as well, so that Git can easily
build its vendored copy of Gitk via a `subproject()` directive. The
instructions can be set up as follows:
$ meson setup build
$ meson compile -C build
$ meson install -C build
Specific options, like for example where Gitk shall be installed to, can
be specified at setup time via `-D`. Available options can be discovered
by running `meson configure` either in the source or build directory.

"git difftool" code clean-up.

difftool: eliminate use of USE_THE_REPOSITORY_VARIABLE

"git rev-list --missing=" learned to accept "print-info" that gives
known details expected of the missing objects, like path and type.
* jt/rev-list-missing-print-info:
rev-list: extend print-info to print missing object type
rev-list: add print-info action to print missing object path
"git push --atomic --porcelain" used to ignore failures from the
other side, losing the error status from the child process, which
has been corrected.
* ps/send-pack-unhide-error-in-atomic-push:
send-pack: gracefully close the connection for atomic push
t5543: atomic push reports exit code failure
send-pack: new return code "ERROR_SEND_PACK_BAD_REF_STATUS"
t5548: add porcelain push test cases for dry-run mode

t5504: modernize test by moving heredocs into test bodies
Lazy-loading missing files in a blobless clone on demand is costly
as it tends to be one-blob-at-a-time. "git backfill" is introduced
to help bulk-download necessary files beforehand.
* ds/backfill:
backfill: assume --sparse when sparse-checkout is enabled
backfill: add --sparse option
backfill: add --min-batch-size=<n> option
backfill: basic functionality and tests
backfill: add builtin boilerplate
The pickaxe options, -G and -S, need either a regex or a string to look
through the history for. An empty value isn't very useful since it
would either match everything or nothing, and what's worse, we presently
crash with a BUG like so when the user provides one:
BUG: diffcore-pickaxe.c:241: should have needle under -G or -S
Since it's not very nice of us to crash and this wouldn't do anything
useful anyway, let's simply inform the user that they must provide a
non-empty argument and exit with an error if they provide an empty one
instead.

Commit 9c93ba4d0a (merge-recursive: honor diff.algorithm, 2024-07-13)
replaced init_merge_options() with init_basic_merge_config() for use in
plumbing commands and init_ui_merge_config() for use in porcelain
commands. As "git merge-tree" is a plumbing command it should call
init_basic_merge_config() rather than init_ui_merge_config(). The merge
ort machinery ignores "diff.algorithm" so the behavior is unchanged by
this commit but it future proofs us against any future changes to
init_ui_merge_config().

real_merge() only ever returns "0" or "1" as it dies if the merge status
is less than zero. Therefore the check for "result < 0" is redundant and
the result variable is not needed. The return value of real_merge() is
ignored because exit status of "git merge-tree --stdin" is "0" for both
successful and conflicted merges (the status of each merge is written to
stdout). The return type of real_merge() is not changed as it is used
for the program's exit status when "--stdin" is not given.

If a process tries to read the output from "git merge-tree --stdin"
before it closes merge-tree's stdin then it deadlocks. This happens
because merge-tree does not flush its output before trying to read
another line of input and means that it is not possible to cherry-pick a
sequence of commits using "git merge-tree --stdin". Fix this by calling
maybe_flush_or_die() before trying to read the next line of
input. Flushing the output after each merge does not seem to affect the
performance, any difference is lost in the noise even after increasing
the number of runs.

Back in 728b9ac0c3 (Makefile(s): avoid recipe prefix in conditional
statements, 2024-04-08), we prepared our Makefiles for a forthcoming
change in upstream Make that would ban the recipe prefix within a
conditional statement by replacing tabs (the prefix) with eight spaces.
In b9d6f64393 (compat/zlib: allow use of zlib-ng as backend,
2025-01-28), a handful of recipe prefix characters were introduced in a
conditional statement ('ifdef ZLIB_NG'), causing 'make' to fail on my
system, which uses GNU Make 4.4.90.
Remove the recipe prefix characters by replacing them with the same
script as is mentioned in 728b9ac0c3.
