@ja-freewnn-*: make FreeWnn-1.1.1-a023 builds with gcc 15

- various fixes to use proper function prototypes for C23
- use proper function types for signal handlers
- use proper variadic arguments to print messages using printf formats
- fix test programs in configure.in and regen configure using
  autoconf 2.72 for modern C23 compilers
- appease more several warnings

- also apply fixes to build FreeWnn on recent Linux distributions:
 - set LC_ALL=C before egrep(1) against EUC files to avoid unexpected
   errors for EUC files
 - use _DEFAULT_SOURCE for Linux rather than obsolete _BSD_SOURCE
   for newer glibc

- update several patch comments properly to clarify each fix
 - gcc 14 enables -Werror=incompatible-pointer-types by default
   but still uses -std=gnu17 by default
 - gcc 15 has switched to -std=gnu23 by default so that old K&R
   style function declarations ("no argument" is treated as "void")
   cause more incompatible-pointer-types and too-many-arguments errors
- remove patches against sources under Xwnmo that seems unmaintained
  (no configure settings) and not enabled by the default builds

Bump PKGREVISIONs.
