Drop X_LOCALE fallback for OS'es without setlocale()

C89 or bust! This was documented as being needed for "only Lynx, Linux-libc5, OS/2" and has never been enabled in modular builds, since none of those platforms have had anyone step up to add support since the X11R7 conversion to autotools. Mostly performed with unifdef -UX_LOCALE, followed by removal of files left without any purpose, and manual cleanup of remaining references.

* Notes:
* 1. 16-bit widechar format is limited to 14 data bits. Since the 2nd byte
* of SJIS multibyte chars are in the ranges of 0x40 - 7E and 0x80 - 0xFC,
* SJIS cannot map directly into 16 bit widechar format within the confines
* of a single codeset. Therefore, for SJIS widechar conversion, SJIS Kanji
* is mapped into the JIS codeset. (The algorithms used in jis_to_sjis()
* and sjis_to_jis() are from Ken Lunde (lunde@mv.us.adobe.com) and are in
* the public domain.)
* 2. Defining FORCE_INDIRECT_CONVERTER (see _XlcEucLoader())
* forces indirect (charset) conversions (e.g. wcstocs()<->cstombs()).
* 3. Using direct converters (e.g. mbstowcs()) decreases conversion
* times by 20-40% (depends on specific converter used).
