Improve ralloc.c interface checking.

See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
* buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
(r_alloc_free) [REL_ALLOC]: Move decls from here ...
* lisp.h (r_alloc, r_alloc_free, r_re_alloc, r_alloc_reset_variable)
[REL_ALLOC]: ... to here, to check interface.
* m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
Remove decls.  This fixes an "It stinks!".
