Previously, the pty master sends inputs to the pipe for cygwin app
even when pseudo console is activated if stdin is not the pty.
This causes the problem that key input is not sent to non cygwin
app even if the app opens CONIN$. This patch sets switch_to_nat_pipe
to true regardless whether stdin is the pty or not to allow that case.

We should not blindly set the home directory of the SYSTEM account (or
of Microsoft accounts) to `/home/<name>`, especially
`/etc/nsswitch.conf` defines `db_home: env`, in which case we want to

Per https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/xbd_chap04.html:
"A pathname that begins with two successive slashes may be interpreted
in an implementation-defined manner, although more than two leading
slashes shall be treated as a single slash."
So more than 2 leading slashes are supposed to be folded into one,
which our dirname neglected. Fix that.

This patch hails from Git for Windows (where the Cygwin runtime is used
in the form of a slightly modified MSYS2 runtime), where it is a
well-established technique to let the `$HOME` variable define where the
current user's home directory is, falling back to `$HOMEDRIVE$HOMEPATH`
and `$USERPROFILE`.
The idea is that we want to share user-specific settings between
programs, whether they be Cygwin, MSYS2 or not. Unfortunately, we
cannot blindly activate the "db_home: windows" setting because in some
setups, the user's home directory is set to a hidden directory via an
UNC path (\\share\some\hidden\folder$) -- something many programs
cannot handle correctly, e.g. `cmd.exe` and other native Windows
applications that users want to employ as Git helpers.
The established technique is to allow setting the user's home directory
via the environment variables mentioned above: `$HOMEDRIVE$HOMEPATH` or
`$USERPROFILE`. This has the additional advantage that it is much
faster than querying the Windows user database.
Of course this scheme needs to be opt-in. For that reason, it needs
to be activated explicitly via `db_home: env` in `/etc/nsswitch.conf`.

Latest Windows supports more EU locales than GLibc, so some of the

The Windows function ResolveLocaleName is next to useless to
convert a partial locale identifier into a full, supported
locale identifier. It converts anything which vaguely resembles
a locale into some other locale it supports.
Bad examples are:
"en-XY" gets converted to "en-US", and worse,
"ff-BF" gets converted to "ff-Latn-SN", even though "ff-Adlm-BF"
exists!
To check if a locale is supported, we have to enumerate all valid
Windows locales, and return the match, even if the locale in Windows
requires a script. Implement resolve_locale_name() as replacement
function for ResolveLocaleName.

Due to the way locales are evaluated in Windows, we can't ask for
the script of the "sd-IN" locale, because Windows only knows the
"sd-Deva-IN" locale. So asking for the script of the "sd" locale
returns "Arab;", because "sd" is converted to "sd-Arab-PK".

If a host NTFS is mapped into a Hyper-V isolated container, the
OPEN_BY_FILE_ID filesystem flag is missing, just as if that NTFS
is a remote drive. However, NtQueryVolumeInformationFile claims
the drive is a local drive.
We can use this fact to learn that the process is running under
Hyper-V, and that the Hyper-V isolated process can't use rename/unlink
with POSIX semantics. Strange enough, the POSIX_UNLINK_RENAME filesystem
flag is still set...

Except for the "C" or "POSIX" locale, checking for start <= finish
is always wrong. Range start must be <= range finish in terms of the
locale's collating order. So make sure to call always wcscoll(), even
in the "C"/"POSIX" locale, which makes wcscoll equivalent to wcscmp
anyway.

computejumps() moves g->charjump to a position relativ to the value of
CHAR_MIN. As such, g->charjump doesn't necessarily point to the address
actually allocated. While regfree() takes that into account, the low
memory handling in regcomp_internal() doesn't. Fix that by free'ing
the actually allocated address, as in regfree().
