On LLP64 systems, such as Windows, the size of `long`, `int`, etc. is
only 32 bits (for backward compatibility). Git's use of `unsigned long`
for file memory sizes in many places, rather than size_t, limits the
handling of large files on LLP64 systems (commonly given as `>4GB`).

Provide a minimum test for handling a >4GB file. The `hash-object`
command, with the  `--literally` and without `-w` option avoids
writing the object, either loose or packed. This avoids the code paths
hitting the `bigFileThreshold` config test code, the zlib code, and the
pack code.

Subsequent patches will walk the test's call chain, converting types to
`size_t` (which is larger in LLP64 data models) where appropriate.

Continue walking the code path for the >4GB `hash-object --literally`
test. The `hash_object_file_literally()` function internally uses both
`hash_object_file()` and `write_object_file_prepare()`. Both function
signatures use `unsigned long` rather than `size_t` for the mem buffer
sizes. Use `size_t` instead, for LLP64 compatibility.

While at it, convert those function's object's header buffer length to
`size_t` for consistency. The value is already upcast to `uintmax_t` for
print format compatibility.

Note: The hash-object test still does not pass. A subsequent commit
continues to walk the call tree's lower level hash functions to identify
further fixes.

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.

Continue walking the code path for the >4GB `hash-object --literally`
test to the hash algorithm step for LLP64 systems.

This patch lets the SHA1DC code use `size_t`, making it compatible with
LLP64 data models (as used e.g. by Windows).

The interested reader of this patch will note that we adjust the
signature of the `git_SHA1DCUpdate()` function without updating _any_
call site. This certainly puzzled at least one reviewer already, so here
is an explanation:

This function is never called directly, but always via the macro
`platform_SHA1_Update`, which is usually called via the macro
`git_SHA1_Update`. However, we never call `git_SHA1_Update()` directly
in `struct git_hash_algo`. Instead, we call `git_hash_sha1_update()`,
which is defined thusly:

    static void git_hash_sha1_update(git_hash_ctx *ctx,
                                     const void *data, size_t len)
    {
        git_SHA1_Update(&ctx->sha1, data, len);
    }

i.e. it contains an implicit downcast from `size_t` to `unsigned long`
(before this here patch). With this patch, there is no downcast anymore.

With this patch, finally, the t1007-hash-object.sh "files over 4GB hash
literally" test case is fixed.

Just like the `hash-object --literally` code path, the `--stdin` code
path also needs to use `size_t` instead of `unsigned long` to represent
memory sizes, otherwise it would cause problems on platforms using the
LLP64 data model (such as Windows).

To limit the scope of the test case, the object is explicitly not
written to the object store, nor are any filters applied.

The `big` file from the previous test case is reused to save setup time;
To avoid relying on that side effect, it is generated if it does not
exist (e.g. when running via `sh t1007-*.sh --long --run=1,41`).

In Git-for-Windows, work on using ARM64 has progressed. The
commit 2d94b77 (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 635b6d9 (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.

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.

In the case of Git for Windows (say, in a Git Bash window) running in a
Windows Subsystem for Linux (WSL) directory, the GetNamedSecurityInfoW()
call in is_path_owned_By_current_side() returns an error code other than
ERROR_SUCCESS. This is consistent behavior across this boundary.

In these cases, the owner would always be different because the WSL
owner is a different entity than the Windows user.

The change here is to suppress the error message that looks like this:

NtQueryObject under Wine can return a success but fill out no name.
In those situations, Wine will set Buffer to NULL, and set result to
the sizeof(OBJECT_NAME_INFORMATION).

Running a command such as

echo "$(git.exe --version 2>/dev/null)"

will crash due to a NULL pointer dereference when the code attempts to
null terminate the buffer, although, weirdly, removing the subshell or
redirecting stdout to a file will not trigger the crash.

Code has been added to also check Buffer and Length to ensure the check
is as robust as possible due to the current behavior being fragile at
best, and could potentially change in the future

This code is based on the behavior of NtQueryObject under wine and

From the documentation of said setting:

	This boolean will enable fsync() when writing object files.

	This is a total waste of time and effort on a filesystem that
	orders data writes properly, but can be useful for filesystems
	that do not use journalling (traditional UNIX filesystems) or
	that only journal metadata and not file contents (OS X’s HFS+,
	or Linux ext3 with "data=writeback").

The most common file system on Windows (NTFS) does not guarantee that
order, therefore a sudden loss of power (or any other event causing an
unclean shutdown) would cause corrupt files (i.e. files filled with
NULs). Therefore we need to change the default.

Note that the documentation makes it sound as if this causes really bad
performance. In reality, writing loose objects is something that is done
only rarely, and only a handful of files at a time.

Whith Windows 2000, Microsoft introduced a flag to the PE header to mark executables as
"terminal server aware". Windows terminal servers provide a redirected Windows directory and
redirected registry hives when launching legacy applications without this flag set. Since we
do not use any INI files in the Windows directory and don't write to the registry, we don't
need  this additional preparation. Telling the OS that we don't need this should provide
slightly improved startup times in terminal server environments.

When building for supported Windows Versions with MSVC the /TSAWARE linker flag is
automatically set, but MinGW requires us to set the --tsaware flag manually.

Support windows container.

Git for Windows accepts pull requests; Core Git does not. Therefore we
need to adjust the template (because it only matches core Git's
project management style, not ours).

Also: direct Git for Windows enhancements to their contributions page,
space out the text for easy reading, and clarify that the mailing list
is plain text, not HTML.

With this patch, Git for Windows works as intended on mounted APFS
volumes (where renaming read-only files would fail).

A fix for calling `vim` in Windows Terminal caused a regression and was
reverted. We partially un-revert this, to get the fix again.

This topic branch re-adds the deprecated --stdin/-z options to `git
reset`. Those patches were overridden by a different set of options in
the upstream Git project before we could propose `--stdin`.

We offered this in MinGit to applications that wanted a safer way to
pass lots of pathspecs to Git, and these applications will need to be
adjusted.

Instead of `--stdin`, `--pathspec-from-file=-` should be used, and
instead of `-z`, `--pathspec-file-nul`.

Originally introduced as `core.useBuiltinFSMonitor` in Git for Windows
and developed, improved and stabilized there, the built-in FSMonitor
only made it into upstream Git (after unnecessarily long hemming and
hawing and throwing overly perfectionist style review sticks into the
spokes) as `core.fsmonitor = true`.

In Git for Windows, with this topic branch, we re-introduce the
now-obsolete config setting, with warnings suggesting to existing users
how to switch to the new config setting, with the intention to
ultimately drop the patch at some stage.
