clean up utf8-ucs4 vs. unistr redundancy

[Bruno Haible]

Hi,

Compiling with -Wall gave me these warnings:

ucs4-utf16.h:33: warning: static declaration for `u16_uctomb' follows non-static
ucs4-utf16.h:33: warning: static declaration for `u16_uctomb' follows non-static
ucs4-utf16.h:33: warning: static declaration for `u16_uctomb' follows non-static
ucs4-utf8.h:33: warning: static declaration for `u8_uctomb' follows non-static
ucs4-utf8.h:33: warning: static declaration for `u8_uctomb' follows non-static
ucs4-utf8.h:33: warning: static declaration for `u8_uctomb' follows non-static

The fix is
  1. to remove the ucs4-utf16.h, ucs4-utf8.h etc. include files, replacing
     them with unistr.h,
  2. to take care of HAVE_INLINE where necessary,
  3. to synchronize the source file names and module descriptions.

Here's the first part of it (showing only the relevant ChangeLog and NEWS
entries).
