* configure.in: use AC_CHECK_FUNCS and check for memmove.

	hash.h: if we don't HAVE_MEMMOVE use bcopy.

Really, though, a quick glance seems to indicate that most of the uses
of memmove could really be handled by memcpy, but I haven't time to prove
it right now. If I'm right, back out this check. (This is for sunos 4 which
has memcpy but not memmove.)
