 defined on ralloc.c.
 src/buffer.c [REL_ALLOC]: Remove prototypes of
 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
 they are now on lisp.h.
 src/ralloc.c (r_alloc_inhibit_buffer_relocation): New function.

 text while re_search_2 is doing its job, because re_search_2 is
 passed C pointers to buffer text.
