b15d11e164 mingw: add a cache below mingw's lstat and dirent implementations
Checking the work tree status is quite slow on Windows, due to slow
`lstat()` emulation (git calls `lstat()` once for each file in the
index). Windows operating system APIs seem to be much better at scanning
the status of entire directories than checking single files.

Add an `lstat()` implementation that uses a cache for lstat data. Cache
misses read the entire parent directory and add it to the cache.
Subsequent `lstat()` calls for the same directory are served directly
from the cache.

Also implement `opendir()`/`readdir()`/`closedir()` so that they create
and use directory listings in the cache.

The cache doesn't track file system changes and doesn't plug into any
modifying file APIs, so it has to be explicitly enabled for git functions
that don't modify the working copy.

Note: in an earlier version of this patch, the cache was always active and
tracked file system changes via ReadDirectoryChangesW. However, this was
much more complex and had negative impact on the performance of modifying
git commands such as 'git checkout'.

a300641f03 CMake: show Win32 and Generator_platform build-option values
Ensure key CMake option values are part of the CMake output to
facilitate user support when tool updates impact the wider CMake
actions, particularly ongoing 'improvements' in Visual Studio.

These CMake displays perform the same function as the build-options.txt
provided in the main Git for Windows. CMake is already chatty.
The setting of CMAKE_EXPORT_COMPILE_COMMANDS is also reported.

Include the environment's CMAKE_EXPORT_COMPILE_COMMANDS value which
may have been propogated to CMake's internal value.

Testing the CMAKE_EXPORT_COMPILE_COMMANDS processing can be difficult
in the Visual Studio environment, as it may be cached in many places.
The 'environment' may include the OS, the user shell, CMake's
own environment, along with the Visual Studio presets and caches.

See previous commit for arefacts that need removing for a clean test.

3d33db718f CMakeLists: add default "x64-windows" arch for Visual Studio
In Git-for-Windows, work on using ARM64 has progressed. The
commit 2d94b77b27 (cmake: allow building for Windows/ARM64, 2020-12-04)
failed to notice that /compat/vcbuild/vcpkg_install.bat will default to
using the "x64-windows" architecture for the vcpkg installation if not set,
but CMake is not told of this default. Commit 635b6d99b3 (vcbuild: install
ARM64 dependencies when building ARM64 binaries, 2020-01-31) later updated
vcpkg_install.bat to accept an arch (%1) parameter, but retained the default.

This default is neccessary for the use case where the project directory is
opened directly in Visual Studio, which will find and build a CMakeLists.txt
file without any parameters, thus expecting use of the default setting.

Also Visual studio will generate internal .sln solution and .vcxproj project
files needed for some extension tools. Inform users of the additional
.sln/.vcxproj generation.

** How to test:
 rm -rf '.vs' # remove old visual studio settings
 rm -rf 'compat/vcbuild/vcpkg' # remove any vcpkg downloads
 rm -rf 'contrib/buildsystems/out' # remove builds & CMake artifacts
 with a fresh Visual Studio Community Edition, File>>Open>>(git *folder*)
   to load the project (which will take some time!).
 check for successful compilation.
The implicit .sln (etc.) are in the hidden .vs directory created by
Visual Studio.

2997adbfb2 CMake: default Visual Studio generator has changed
Correct some wording and inform users regarding the Visual Studio
changes (from V16.6) to the default generator.

Subsequent commits ensure that Git for Windows can be directly
opened in modern Visual Studio without needing special configuration
of the CMakeLists settings.

It appeares that internally Visual Studio creates it's own version of the
.sln file (etc.) for extension tools that expect them.

The large number of references below document the shifting of Visual Studio
default and CMake setting options.

0f1d3ff2f7 win32: add a helper to run git.exe without a foreground window
On Windows, there are two kinds of executables, console ones and
non-console ones. Git's executables are all console ones.

When launching the former e.g. in a scheduled task, a CMD window pops
up. This is not what we want for the tasks installed via the `git
maintenance` command.

To work around this, let's introduce `headless-git.exe`, which is a
non-console program that does _not_ pop up any window. All it does is to
re-launch `git.exe`, suppressing that console window, passing through
all command-line arguments as-are.

d279ea7a7c subtree: update contrib/subtree test target
The intention of this change is to align with how the top-level git
`Makefile` defines its own test target (which also internally calls
`$(MAKE) -C t/ all`). This change also ensures the consistency of
`make -C contrib/subtree test` with other testing in CI executions
(which rely on `$DEFAULT_TEST_TARGET` being defined as `prove`).

bac20c5ba5 cmake(): allow setting HOST_CPU for cross-compilation
Git's regular Makefile mentions that HOST_CPU should be defined when cross-compiling Git: 37796bca76/Makefile (L438-L439)

This is then used to set the GIT_HOST_CPU variable when compiling Git: 37796bca76/Makefile (L1337-L1341)

Then, when the user runs `git version --build-options`, it returns that value: 37796bca76/help.c (L658)

This commit adds the same functionality to the CMake configuration. Users can now set -DHOST_CPU= to set the target architecture.

efa188a094 vcxproj: handle resource files, too
On Windows, we also compile a "resource" file, which is similar to
source code, but contains metadata (such as the program version).

So far, we did not compile it in `MSVC` mode, only when compiling Git
for Windows with the GNU C Compiler.

In preparation for including it also when compiling with MS Visual C,
let's teach our `vcxproj` generator to handle those sort of files, too.

5b9d697770 vcxproj: unclash project directories with build outputs
It already caused problems with the test suite that the directory
containing `git.vcxproj` is called the same as the Git executable
without its file extension: `./git` is ambiguous, it could refer both to
the directory `git/` as well as to `git.exe`.

Now there is one more problem: when our GitHub workflow runs on the
`vs/master` branch, it fails in all but the Windows builds, as they want
to write the file `git` but there is already a directory in the way.

Let's just go ahead and append `.proj` to all of those directories, e.g.
`git.proj/` instead of `git/`.

be6444d1ca completion: bash: add correct suffix in variables
__gitcomp automatically adds a suffix, but __gitcomp_nl and others
don't, we need to specify a space by default.

Can be tested with:

  git config branch.autoSetupMe<tab>

This fix only works for versions of bash greater than 4.0, before that
"local sfx" creates an empty string, therefore the unset expansion
doesn't work. The same happens in zsh.

Therefore we don't add the test for that for now.

The correct fix for all shells requires semantic changes in __gitcomp,
but that can be done later.

50101b93ca cmake(windows): set correct path to the system Git config
Currently, when Git for Windows is built with CMake, the system Git config is
expected in a different location than when building via `make`: the former
expects it to be in `<runtime-prefix>/mingw64/etc/gitconfig`, the latter in
`<runtime-prefix>/etc/gitconfig`.

Because of this, things like `git clone` do not work correctly (because cURL is
no longer able to find its certificate bundle that it needs to validate HTTPS
certificates). See the full bug report and discussion here:
https://github.com/git-for-windows/git/issues/3071#issuecomment-789261386.

This commit aligns the CMake-based build by mimicking what is already done in
`config.mak.uname`.

cea232194d completion: bash: fix late declaration of __git_cmd_idx
A recent update to contrib/completion/git-completion.bash causes bash to fail
auto complete custom commands that are wrapped with __git_func_wrap. Declaring
__git_cmd_idx=0 inside __git_func_wrap resolves the issue.

77f37de39f subtree: fix assumption about the directory separator
On Windows, both forward and backslash are valid separators. In
22d5507493 (subtree: don't fuss with PATH, 2021-04-27), however, we
added code that assumes that it can only be the forward slash.

Let's fix that.

f7ee88f1d0 subtree: fix the GIT_EXEC_PATH sanity check to work on Windows
In 22d5507493 (subtree: don't fuss with PATH, 2021-04-27), `git
subtree` was broken thoroughly on Windows.

The reason is that it assumes Unix semantics, where `PATH` is
colon-separated, and it assumes that `$GIT_EXEC_PATH:` is a verbatim
prefix of `$PATH`. Neither are true, the latter in particular because
`GIT_EXEC_PATH` is a Windows-style path, while `PATH` is a Unix-style
path list.

Let's make extra certain that `$GIT_EXEC_PATH` and the first component
of `$PATH` refer to different entities before erroring out.

We do that by using the `test <path1> -ef <path2>` command that verifies
that the inode of `<path1>` and of `<path2>` is the same.

Sadly, this construct is non-portable, according to
https://pubs.opengroup.org/onlinepubs/009695399/utilities/test.html.
However, it does not matter in practice because we still first look
whether `$GIT_EXEC_PREFIX` is string-identical to the first component of
`$PATH`. This will give us the expected result everywhere but in Git for
Windows, and Git for Windows' own Bash _does_ handle the `-ef` operator.

Just in case that we _do_ need to show the error message _and_ are
running in a shell that lacks support for `-ef`, we simply suppress the
error output for that part.

This fixes https://github.com/git-for-windows/git/issues/3260

409047a2b3 cmake: create compile_commands.json by default
Some users have expressed interest in a more "batteries included" way of
building via CMake[1], and a big part of that is providing easier access
to tooling external tools.

A straightforward way to accomplish this is to make it as simple as
possible is to enable the generation of the compile_commands.json file,
which is supported by many tools such as: clang-tidy, clang-format,
sourcetrail, etc.

This does come with a small run-time overhead during the configuration
step (~6 seconds on my machine):

    Time to configure with CMAKE_EXPORT_COMPILE_COMMANDS=TRUE

    real    1m9.840s
    user    0m0.031s
    sys     0m0.031s

    Time to configure with CMAKE_EXPORT_COMPILE_COMMANDS=FALSE

    real    1m3.195s
    user    0m0.015s
    sys     0m0.015s

This seems like a small enough price to pay to make the project more
accessible to newer users.  Additionally there are other large projects
like llvm [2] which has had this enabled by default for >6 years at the
time of this writing, and no real negative consequences that I can find
with my search-skills.

NOTE: That the compile_commands.json is currently produced only when
using the Ninja and Makefile generators.  See The CMake documentation[3]
for more info.

cd0a852981 cmake: add knob to disable vcpkg
When building on windows users have the option to use vcpkg to provide
the dependencies needed to compile.  Previously, this was used only when
using the Visual Studio generator which was not ideal because:

  - Not all users who want to use vcpkg use the Visual Studio
    generators.

  - Some versions of Visual Studio 2019 moved away from using the
    VS 2019  generator by default, making it impossible for Visual
    Studio to configure the project in the likely event that it couldn't
    find the dependencies.

  - Inexperienced users of CMake are very likely to get tripped up by
    the errors caused by a lack of vcpkg, making the above bullet point
    both annoying and hard to debug.

As such, let's make using vcpkg the default on windows.  Users who want
to avoid using vcpkg can disable it by passing -DNO_VCPKG=TRUE.

f74d11471f multimail: stop shipping a copy
The multimail project is developed independently and has its own project
page. Traditionally, we shipped a copy in contrib/.

However, such a copy is prone to become stale, and users are much better
served to be directed to the actual project instead.

0b18023d00 contrib/completion: fix zsh completion regression from 59d85a2a05
A recent change to make git-completion.bash use $__git_cmd_idx
in more places broke a number of completions on zsh because it
modified __git_main but did not update __git_zsh_main.

Notably, completions for "add", "branch", "mv" and "push" were
broken as a result of this change.

In addition to the undefined variable usage, "git mv <tab>" also
prints the following error:

	__git_count_arguments:7: bad math expression:
	operand expected at `"1"'

	_git_mv:[:7: unknown condition: -gt

Remove the quotes around $__git_cmd_idx in __git_count_arguments
and set __git_cmd_idx=1 early in __git_zsh_main to fix the
regressions from 59d85a2a05.

This was tested on zsh 5.7.1 (x86_64-apple-darwin19.0).

Simple IPC always requires threads (in addition to various

to define SUPPORTS_SIMPLE_IPC when appropriate.

Previously, the Unix version of the code would only verify that
Unix domain sockets were available.
