  unistr/u{16,32}-strstr: Use two-way algorithm (no memory allocation).
  
  * lib/wcs-two-way.h: Use UNIT instead of wchar_t. Don't undefine
  RETURN_TYPE.
  * lib/wcsstr-impl.h: Move the non-linear implementation away. Use UNIT
  instead of wchar_t, RETURN_TYPE instead of 'wchar_t *', FUNC instead of
  wcsstr.
  (AVAILABLE): Use MEMCHR0 instead of wmemchr.
  (FUNC): Use STRCHR instead of wcschr.
  * lib/wcsstr.c: Moved the non-linear implementation to here.
  (FUNC, UNIT, RETURN_TYPE, MEMCHR0, STRCHR): New macros.
  * lib/unistr/u16-strstr.c: Don't include malloca.h, str-kmp.h,
  u-strstr.h. Instead, include wcsstr-impl.h.
  * lib/unistr/u32-strstr.c: Likewise.
  * modules/unistr/u16-strstr (Files): Remove u-strstr.h, str-kmp.h. Add
  wcsstr-impl.h, wcs-two-way.h.
  (Depends-on): Remove u16-strmbtouc, u16-strlen, u16-strnlen, malloca.
  Add u16-chr, u16-cmp.
  * modules/unistr/u32-strstr (Files): Remove u-strstr.h, str-kmp.h. Add
  wcsstr-impl.h, wcs-two-way.h.
  (Depends-on): Remove u32-strlen, u32-strnlen, malloca. Add u32-chr,
  u32-cmp.
