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

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.

Since Windows Vista, locale handling is converted from using numeric
locale identifiers (LCID) to using ISO5646 locale strings. In the
meantime Windows introduced new locales which don't even have a LCID
attached. Those were unusable in Cygwin because locale information
for these locales required to call the new locale functions taking
a locale string.
Convert Cygwin to drop LCIDs and use Windows ISO5646 locales instead.
The last place using LCIDs is the __set_charset_from_locale function.
Checking numerically is easier and uslay faster than checking strings.
However, this function is clearly a TODO
Used on Linux as default codeset for Tajik. There's no matching
Windows codepage, so fake it as CP103.

LCIDs are deprecated since Windows Vista. Worse, lots of new locales
have been added in the meantime which have no LCID attached. They
are only available by locale name.
As first step, rearrange the locale(1) tool to use Windows locale
names, rather than LCIDs, so we can now enumerate *all* locales
available in more recent Windows versions.

Most locales using latin characters ignore case while sorting.
This is what wcscoll does (correctly so). However, there's an
internal order of collating sequences compared to the base
character, which is case-sensitive, at least in GLibc.
There's no way to express this in Windows, because CompareString
and LCMapString *always* use case-insensitivity in those locales,
even if none of the *IGNORECASE sorting flags are used.
We want to follow glibc's behaviour more closely, so we add an
extra check for the case and make sure upper and lower cased
letters don't comapre as identical.

Rather than converting single chars on the fly to lowercase
in case ignore_case_with_glob is set, perform the conversion
on the entire input (pattern and filenames).
