Before we had CMake support, the only way to build Git in Visual Studio
was via this hacky `generate` script.
For a while I tried to fix whenever things got broken, in particular to
allow building confidence in embargoed releases by running the CI builds
in Azure Pipelines in a private Azure DevOps project. I even carried the
patches in Git for Windows with the intention of upstreaming them,
eventually.
However, it is a lot of work with too little benefit. CMake is much
better supported by Visual Studio. So let's drop this hacky script (plus
support code).

The Meson build for coccinelle static analysis lists all headers to
analyse. Due to the way Meson exports variables between subdirs, this
variable is also available in the root Meson build.
An upcoming commit, will add a new check complimenting 'hdr-check' in
the Makefile. This would require the list of headers. So move the
'coccinelle_headers' to the root Meson build and rename it to 'headers',
remove the root path being appended to each header and retain that in
the coccinelle Meson build since it is specific to the coccinelle build.
Also move the 'third_party_sources' variable to the root Meson build
since it is also a dependency for the 'headers' variable. This also
makes it easier to understand as the variable is now propagated from the
top level to the bottom.
While 'headers_to_check' is only computed when we have a repository and
the 'git' executable is present, the variable itself is exposed as an
empty array. This allows dependencies in upcoming commits to simply
check for length of the array and not worry about dependencies required
to actually populate the array.

In Meson, included subdirs export their variables to top level Meson
builds. In 'contrib/coccinelle/meson.build', we define two such
variables `sources` and `headers`. While these variables are specific to
the checks in the 'contrib/coccinelle/' directory, they also pollute the
top level 'meson.build'.
Rename them to be more specific, this ensures that they aren't
mistakenly used in the upper levels and avoid variable name collisions.
While here, change the empty list denotation to be consistent with other
places.

The shell completion scripts in "contrib/completion" are being tested,
but none of our build systems support installing them. This is somewhat
confusing for Meson, where users can explicitly enable building these
scripts via `-Dcontrib=completion`. This option only controlls whether
the completions are built and tested against, where "building" is a bit
of an euphemism for "copying them into the build directory".
Teach both our Makefile and Meson to install our Bash completion script.
For now, this is the only completion script that we're installing given
that Bash completions "just work" with a canonical well-known location
nowadays. Other completion scripts, like for example the one for zsh,
don't have a well-known location and/or require extra steps by the user
to make them available. As such, we skip installing these scripts for
now, but we may do so in the future if we ever figure out a proper way
to do this.

Wiring up coccinelle in the build, depends on running git commands to
get the list of files to operate on. Reasonable, for a feature mainly
used by people developing on git. If building git itself from a tarball
distribution of git's own source code, one likely does not need to run
coccinelle.
But running those git commands failed, and caused the build to error
out, if `spatch` was installed -- because the build assumed that its
presence indicated a desire to use it on this source tree. Instead, we
can expand the conditional to check for both `spatch` and the `.git`
file or directory.
Meson's `opt.require()` method allows us to add a prerequisite for the
feature option. If the prerequisite fails, then the option either:
- converts autodetection to disabled
- emits an informative error if the feature was set to enabled:
```
ERROR: Feature coccinelle cannot be enabled: coccinelle can only be run from a git checkout

Introduce libgit-sys, a Rust wrapper crate that allows Rust code to call
functions in libgit.a. This initial patch defines build rules and an
interface that exposes user agent string getter functions as a proof of
concept. This library can be tested with `cargo test`. In later commits,
a higher-level library containing a more Rust-friendly interface will be
added at `contrib/libgit-rs`.
Symbols in libgit can collide with symbols from other libraries such as
libgit2. We avoid this by first exposing library symbols in
public_symbol_export.[ch]. These symbols are prepended with "libgit_" to
avoid collisions and set to visible using a visibility pragma. In
build.rs, Rust builds contrib/libgit-rs/libgit-sys/libgitpub.a, which also
contains libgit.a and other dependent libraries, with
-fvisibility=hidden to hide all symbols within those libraries that
haven't been exposed with a visibility pragma.

Commit 1e0ee4087e (completion: add and use
__git_compute_first_level_config_vars_for_section, 2024-02-10) uses an
indirect variable syntax that is only valid for Bash, but the Zsh
completion code relies on the Bash completion code to function. Zsh
supports a different indirect variable expansion using ${(P)var}, but in
`emulate ksh` mode does not support Bash's ${!var}.
This manifests as completing strange config options like
"__git_first_level_config_vars_for_section_remote" as a choice for the
command line
git config set remote.
Using Zsh's C-x ? _complete_debug widget with the cursor at the end of
that command line captures a trace, in which we see (some details
elided):
+__git_complete_config_variable_name:7> __git_compute_first_level_config_vars_for_section remote

+__gitcomp_nl:7> compadd -Q -S ' ' -p remote. -- __git_first_level_config_vars_for_section_remote
We perform the test for __git_compute_config_vars correctly, but the
${!this_section} references are not expanded as expected.
Instead, portably expand indirect references through the new
__git_indirect. Contrary to some versions you might find online [1],
this version avoids echo non-portabilities [2] [3] and correctly quotes
the indirect expansion after eval (so that the result is not split or
globbed before being handed to printf).

[2]: https://askubuntu.com/questions/715765/mysterious-behavior-of-echo-command#comment1056038_715769
[3]: https://mywiki.wooledge.org/CatEchoLs
The following demo program demonstrates how this works:
b=1
indirect() {
eval printf '%s' "\"\$$1\""
}
f() {
# Comment this out to see that it works for globals, too. Or, use
# a value with spaces like '2 3 4' to see how it handles those.
local b=2
local a=b
test -n "$(indirect $a)" && echo nice
}
f
When placed in a file "demo", then both
bash -x demo
and
zsh -xc 'emulate ksh -c ". ./demo"' |& tail
provide traces showing that "$(indirect $a)" produces 2 (or 1, with the
global, or "2 3 4" as a single string, etc.).

Building our "gitweb" interface is optional in our Makefile and in Meson
and not wired up at all with CMake, but disabling it causes a couple of
tests in the t950* range that pull in "t/lib-gitweb.sh". This is because
the test library knows to execute gitweb-tests based on whether or not
Perl is available, but we may have Perl available and still end up not
building gitweb e.g. with `make test NO_GITWEB=YesPlease`.
Fix this issue by wiring up a new "NO_GITWEB" build option so that we
can skip these tests in case gitweb is not built.
Note that this new build option requires us to move the configuration of
GIT-BUILD-OPTIONS to a later point in our Meson build instructions. But
as that file is only consumed by our tests at runtime this change does
not cause any issues.
