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'.

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.

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.

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!).

The implicit .sln (etc.) are in the hidden .vs directory created by
Visual Studio.

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`).

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/`.

Windows updates.
* ds/maintenance-on-windows-fix:
git maintenance: avoid console window in scheduled tasks on Windows
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.

Reduce reliance on a global state in the config reading API.
* gc/config-context:
config: pass source to config_parser_event_fn_t
config: add kvi.path, use it to evaluate includes
config.c: remove config_reader from configsets
config: pass kvi to die_bad_number()
trace2: plumb config kvi
config.c: pass ctx with CLI config
config: pass ctx with config files
config.c: pass ctx in configsets
config: add ctx arg to config_fn_t
urlmatch.h: use config_fn_t type
config: inline git_color_default_config
Plumb "struct key_value_info" through all code paths that end in
die_bad_number(), which lets us remove the helper functions that read
analogous values from "struct config_reader". As a result, nothing reads
config_reader.config_kvi any more, so remove that too.
In config.c, this requires changing the signature of
git_configset_get_value() to 'return' "kvi" in an out parameter so that
git_configset_get_<type>() can pass it to git_config_<type>(). Only
numeric types will use "kvi", so for non-numeric types (e.g.
git_configset_get_string()), pass NULL to indicate that the out
parameter isn't needed.
Outside of config.c, config callbacks now need to pass "ctx->kvi" to any
of the git_config_<type>() functions that parse a config string into a
number type. Included is a .cocci patch to make that refactor.
The only exceptional case is builtin/config.c, where git_config_<type>()
is called outside of a config callback (namely, on user-provided input),
so config source information has never been available. In this case,
die_bad_number() defaults to a generic, but perfectly descriptive
message. Let's provide a safe, non-NULL for "kvi" anyway, but make sure
not to change the message.

Add a new "const struct config_context *ctx" arg to config_fn_t to hold
additional information about the config iteration operation.
config_context has a "struct key_value_info kvi" member that holds
metadata about the config source being read (e.g. what kind of config
source it is, the filename, etc). In this series, we're only interested
in .kvi, so we could have just used "struct key_value_info" as an arg,
but config_context makes it possible to add/adjust members in the future
without changing the config_fn_t signature. We could also consider other
ways of organizing the args (e.g. moving the config name and value into
config_context or key_value_info), but in my experiments, the
incremental benefit doesn't justify the added complexity (e.g. a
config_fn_t will sometimes invoke another config_fn_t but with a
different config value).
In subsequent commits, the .kvi member will replace the global "struct
config_reader" in config.c, making config iteration a global-free
operation. It requires much more work for the machinery to provide
meaningful values of .kvi, so for now, merely change the signature and
call sites, pass NULL as a placeholder value, and don't rely on the arg
in any meaningful way.
Most of the changes are performed by
contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every
config_fn_t:
- Modifies the signature to accept "const struct config_context *ctx"
- Passes "ctx" to any inner config_fn_t, if needed
- Adds UNUSED attributes to "ctx", if needed
Most config_fn_t instances are easily identified by seeing if they are
called by the various config functions. Most of the remaining ones are
manually named in the .cocci patch. Manual cleanups are still needed,
but the majority of it is trivial; it's either adjusting config_fn_t
that the .cocci patch didn't catch, or adding forward declarations of
"struct config_context ctx" to make the signatures make sense.
The non-trivial changes are in cases where we are invoking a config_fn_t
outside of config machinery, and we now need to decide what value of
"ctx" to pass. These cases are:
- trace2/tr2_cfg.c:tr2_cfg_set_fl()
This is indirectly called by git_config_set() so that the trace2
machinery can notice the new config values and update its settings
using the tr2 config parsing function, i.e. tr2_cfg_cb().
- builtin/checkout.c:checkout_main()
This calls git_xmerge_config() as a shorthand for parsing a CLI arg.
This might be worth refactoring away in the future, since
git_xmerge_config() can call git_default_config(), which can do much
more than just parsing.
Handle them by creating a KVI_INIT macro that initializes "struct
key_value_info" to a reasonable default, and use that to construct the
"ctx" arg.
