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

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).
g_Ctoc, converting the UTF-32 filenames to multibyte, still
used UTF-16 to multibyte conversion. Introduce a wirtomb

is_unicode_equiv compares two UTF-32 values and returns 1 if
both are member of the same Unicode equivalence class, 0 otherwise.
Note that this function only works with precomposed characters
per Unicode normalization form C. It doesn't handle decomposed
characters, just like its counterpart in glibc. I.e., equivalence
class comparison using decomposed chars won't work. Example:
fnmatch("[=n=]", "ñ") == 0
fnmatch("[=ñ=]", "n") == 0
but
fnmatch("[=n=]", "n\x0303") == 1
fnmatch("[=n\x0303=]", "n") == 1
fnmatch("[=n\x0303=]", "n\x0303") == 1

Given how UTF-16 isn't capable to hold all Unicode chars in a single
wchar_t, we need a function returning a wint_t value representing
a UTF-32 value for comparison functions. Fortunately the important
wide character functions like towupper/towlower, isw<class>, iswctype,
etc, already take wint_t values and newlib handles them as UTF-32.
If only we had switched wchar_t to 32 bit way back when... sigh.

Avoid the mistake fixed in the preceeding commit by passing

commit bc444e5aa4 introduced a call to get_posix_access()
with a NULL pointer for the mode_t parameter because the value
is not needed later on... entirely ignoring the fact that the
mode_t bits are checked for the object being a directory.
In turn, the get_posix_access() call never checked for default
ACEs and returned only the standard ACEs. Thus, every chmod call
on a directory dropped the default ACEs from its permissions, as
well as the default NULL deny-ACE used to store specific bits.
It got also impossible to set the sgid bit on directories.

Older coreutils created directories with mode bits filtered through
umask. Newer coreutils creates directories with full permissions,
0777 by default.
This new coreutils behaviour uncovered the fact that default ACEs for
newly created directories were not filtered by umask starting with
commit bc444e5aa4.
Fix it by applying umask on the default ACEs.

This patch is for the sake of gnulib.
gnulib implements some form of a thread-safe setlocale variant
called setlocale_null_r, which is supposed to return the locale
strings in a thread-safe manner. This only succeeds if the system's
setlocale already handles this thread-safe, otherwise gnulib adds
some locking on its own.
Newlib's setlocale always writes the global string array holding the
LC_ALL value anew on each invocation of setlocale(LC_ALL, NULL).
Since that doesn't allow to call setlocale(LC_ALL, NULL) in a
thread-safe manner, so locking in gnulib is required.
And here's the problem...
The lock is decorated as dllexport when building for Cygwin. This
collides with the default behaviour of ld to export all symbols.
If it finds one decorated symbol, it will only export this symbol
to the DLL import lib.
Change setlocale so that it writes the global string array
holding the LC_ALL value at the time the locale gets changed.
On setlocale(LC_ALL, NULL), just return the pointer to the
global LC_ALL string array, just as in GLibc. The burden of
doing so is negligibly for all targets, but adds thread-safety
for gnulib's setlocal_null_r() function, and gnulib can drop
the lock entirely when building for Cygwin.
