- Remove charset parameter from low level __foo_wctomb/__foo_mbtowc calls.
- Instead, create array of function for ISO and Windows codepages to point
to function which does not require to evaluate the charset string on
each call. Create matching helper functions. I.e., __iso_wctomb,
__iso_mbtowc, __cp_wctomb and __cp_mbtowc are functions returning the
right function pointer now.
- Create __WCTOMB/__MBTOWC macros utilizing per-reent locale and replace
calls to __wctomb/__mbtowc with calls to __WCTOMB/__MBTOWC.
- Drop global __wctomb/__mbtowc vars.
- Utilize aforementioned changes in Cygwin to get rid of charset in other,
calling functions and simplify the code.
- In Cygwin restrict global cygheap locale info to the job performed
by internal_setlocale. Use UTF-8 instead of ASCII on the fly in
internal conversion functions.
- In Cygwin dll_entry, make sure to initialize a TLS area with a NULL
_REENT->_locale pointer. Add comment to explain why.

Move all locale category structure definitions into setlocale.h and remove
other headers in locale subdir. Create inline accessor functions for
current category struct pointers and use throughout. Use pointers to
"C" locale category structs by default in __global_locale.

Throughout, remove references to __STRICT_ANSI__ and use the proper
internal macros and versions for C99, POSIX, ATFILE for the various *at
functions, or LARGEFILE for fseeko and ftello.
[v]asprintf are GNU extensions, but the *iprintf, *iscanf, and
*asnprintf functions are unique to newlib.
getw and putw were removed from POSIX.1-2001. funopen is BSD, and

Newlib's setvbuf function is very old and has two bugs:
- It sets the SRD/SWR flags incorrectly in case of files opened for
reading and writing.
See https://cygwin.com/ml/cygwin/2016-03/msg00180.html
for a desription of the effect.
- It always sets the buffer size to BUFSIZ if it's not provided by
the application, independent of the optimal blocksize for the
underlying IO device.
Update setvbuf to latest code from OpenBSD to fix both problems.

- use bullet points to separate width, size and type sections, rather than using
rows in an enormous table, for consistency with sprintf and swprintf.
- use code markup for size bullet point for consistency
- use a texinfo multitable for description of the size flags, rather than some
preformatted text
- tidy up some whitespace so type flags are all aligned

The CHECK_INIT() is necessary before the _newlib_flockfile_start() since
this would use otherwise acquire an uninitialized lock which gets
initialized after this leading to a corrupt release.
