[ChangeLog]

Assume support for memcmp, memcpy, memmove, memset.
This simplifies the code a bit.  All current platforms have these,
as they are required for C89.  If this turns into a problem we
can add the gnulib modules for these (a 1-line change to Makefile.in).
* configure.in: Don't check for memcmp, memcpy, memmove, memset.
[lib-src/ChangeLog]
Assume support for memcmp, memcpy, memmove, memset.
* etags.c (absolute_filename): Assume memmove exists.
[src/ChangeLog]
Assume support for memcmp, memcpy, memmove, memset.
* lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
* regex.c (memcmp, memcpy):
Remove; we assume C89 now.

* gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
(__malloc_safe_bcopy): Remove; no longer needed.
