* configure.in (USE_MMAP_FOR_BUFFERS): Recognize in system
configuration files instead of REL_ALLOC_MMAP. Set REL_ALLOC
to `no' if defined. Change result report.

* s/freebsd.h, s/irix-5.0.h, s/sol2.h, s/template.h
(USE_MMAP_FOR_BUFFERS): Define instead of REL_ALLOC_MMAP.
* Makefile.in (mallocobj) [SYSTEM_MALLOC]: Don't add ralloc.o.
* emacs.c: Change conditional compilation on REL_ALLOC_MMAP to
USE_MMAP_FOR_BUFFERS.
* insdel.c (make_gap): Use enlarge_buffer_text.
* buffer.c: Move allocation with mmap here, from ralloc.c. Change
conditional compilation on REL_ALLOC_MMAP to USE_MMAP_FOR_BUFFERS.
(mmap_alloc, mmap_free, mmap_realloc) [REL_ALLOC_MMAP]: Renamed
from former r_alloc_* functions in ralloc.c.
(mmap_page_size, mmap_initialized_p) [REL_ALLOC_MMAP]: New
variables.
(MEM_ALIGN) [REL_ALLOC_MMAP]: New macro.
(mmap_init) [REL_ALLOC_MMAP]: New function.
(alloc_buffer_text, enlarge_buffer_text, free_buffer_text): New
functions replacing macros BUFFER_ALLOC, BUFFER_REALLOC, and
BUFFER_FREE.
* buffer.h (BUFFER_ALLOC, BUFFER_REALLOC, BUFFER_FREE): Removed.
(enlarge_buffer_text): Add prototype.
* ralloc.c: Remove everything having to do with the use of mmap.
