  dfa: Overcome wchar_t limitations.
  
  * lib/localeinfo.h: Include <uchar.h>. Add special definitions for GAWK.
  (case_folded_counterparts): Change array element type to char32_t.
  * lib/localeinfo.c: Include <uchar.h>. Add special definitions for GAWK.
  (is_using_utf8, init_localeinfo): Use mbrtoc32 instead of mbrtowc.
  (lonesome_lower): Change element type to 'unsigned short'.
  (case_folded_counterparts): Change array element type to char32_t. Use
  c32toupper instead of towupper. Use c32tolower instead of towlower.
  * lib/dfa.c: Include <uchar.h>. Add special definitions for GAWK.
  (struct mb_char_classes): Change element type of 'chars' to char32_t.
  (mbs_to_wchar): Use mbrtoc32 instead of mbrtowc.
  (setbit_wc): Change type of first argument to char32_t. Use c32tob
  instead of wctob.
  (parse_bracket_exp): Update.
  (lex): Use c32isprint instead of iswprint. Use c32isspace instead of
  iswspace. Use c32rtomb instead of a %lc directive.
  (addtok_wc): Use c32rtomb instead of wcrtomb.
  (atom): Update.
  * modules/dfa (Depends-on): Remove wctype-h. Add uchar,
  mbrtoc32-regular, c32rtomb, c32tob, c32tolower, c32toupper, c32isprint,
  c32isspace.
  (Link): Add $(LIBUNISTRING) $(LIBC32CONV).
  * modules/dfa-tests (Makefile.am): Link test-dfa-match-aux with
  $(LIBUNISTRING) $(LIBC32CONV).
  * NEWS: Mention the change.
