Git for Windows doesn't support anything prior to Windows 8.1 since 2.47.0
and Git followed along with commits like ce6ccba (mingw: drop Windows
7-specific work-around, 2025-08-04).
There is no need to pretend to the compiler that we still support Windows
Vista, just to lock us out of easy access to newer APIs. There is also no
need to have conflicting and unused definitions claiming we support some
versions of Windows XP or even Windows NT 4.0.
Bump all definitions of _WIN32_WINNT to a realistic value of Windows 8.1.
This will also simplify code for a followup commit that will improve cpu
core detection on multi-socket systems.

Commit 85127bcdea ("backfill: assume --sparse when sparse-checkout is
enabled") intended for 'git backfill' to consult the repository
configuration when the user does not pass '--sparse' or
'--no-sparse' on the command line. It added the sentinel check:
if (ctx->sparse < 0)
ctx->sparse = cfg->apply_sparse_checkout;
However, the ctx->sparse field is initialized to 0 instead of -1,
so this guard never triggers. Consequently, the repository config
(core.sparseCheckout) is never checked, and the command always
performs a full backfill even when sparse-checkout is enabled.
Fix this by initializing ctx->sparse to -1, ensuring the existing
fallback logic correctly reads the repository configuration when
no explicit flags are provided.
Add a test to verify that 'git backfill' automatically respects
sparse-checkout settings when no flags are passed.

While the currently used way to detect the number of CPU cores ond
Windows is nice and straight-forward, GetSystemInfo() only [gives us
access to the number of processors within the current
group.](https://learn.microsoft.com/en-us/windows/win32/api/sysinfoapi/ns-sysinfoapi-system_info#members)
While that is usually fine for systems with a single physical CPU,
separate physical sockets are typically separate groups.
Switch to using GetLogicalProcessorInformationEx() to handle
multi-socket
systems better.
I've tested this on a physical single-socket x86-64 and a physical
dual-socket x86-64 system, and on a virtual single-socket ARM64 system.
Physical [multi-socket ARM64 systems seem to
exist](https://cloudbase.it/ampere-altra-industry-leading-arm64-server/),
but I don't have access to such hardware and the hypervisor I use
apparently can't emulate that either.

The `mingw_strftime()` wrapper exists to work around msvcrt.dll's
incomplete `strftime()` implementation by dynamically loading the
version from ucrtbase.dll at runtime via `LoadLibrary()` +
`GetProcAddress()`. When the binary is already linked against UCRT
(i.e. when building in the UCRT64 environment), the linked-in
`strftime()` is the ucrtbase.dll version, making the dynamic loading
needless churn: It's calling the very same code.
Simply guard both the declaration and implementation so that the
unnecessary work-around is skipped in UCRT builds.

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.

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`.
