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...

These flags are used to check a remote filesystem. Not all
flags supported by a local NTFS are available when checking
a remote NTFS. Fix the flag set accordingly, otherwise
the remote NTFS will ba handled as CIFS.

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().

Take the opportunity to follow FreeBSD's and Linux's lead in recasting
macro inline code as calls to static inline functions. This allows the
macros to be type-safe. In addition, added a lower bound check to the
functions that use a cpu number to avoid a potential buffer underrun on
a bad argument. h/t to Corinna for the advice on recasting.

The conversion function g_Ctoc missed to drop the flag
values from the wint_t value. That wasn't noticable with
the original version because it used a 64 bit Char type
and the flags were in the upper 32 bit region. So the
flag values were silently dropped when wcrtomb was called.
After converting Char to wint_t, we have to do drop the
flags explicitely.

If a CPU implements EL2 as its highest exception level then programs
using newlib may start in hypervisor mode. In that state it is not
trivial to switch into the various EL1 modes to configure the
individual exception stacks, so do not try.
This requires quite a few changes in how fnmatch operates.
It always operates on wint_t strings now, just like regex and glob,
and it always keeps a pointer on the character inside the string,
rather than operating on a single character.
As a result, just drop the ifdef's for Cygwin. The code is
non-portable now anyway...

Deviation from standard: If the input is broken, the output will be
broken. I. e., we just copy the current byte over into the wint_t
destination and try to pick up on the next byte. This is in line
with the way fnmatch works.

The existing code checked if there was a chunk in free_list and
that the tail was not the next chunk.
The check if there is a chunk is not needed since it's already
known but the case of a single chunk in free_list needs to be
handled differently.
As the former call to `locale -av' has the unwanted side effect
to shorten the locale name to <= 15 chars, don't use it. Use
`locale -a' instead and fetch the codeset from another call to
`locale' for each locale.

Effectively revert commit 57bac33359. The fact that the

So far locale(1) had to have knowledge how to construct, thus
duplicating the effort how Cygwin handles locale strings.
Move locale list and codeset list generation into Cygwin by
providing /proc/codesets and /proc/locales files. /proc/locales
does not list aliases, those are still handled in locale(1).
locale(1) opens the files and ueses that info for printing,
like any other application can do now.
