Improve gdbm_setopt interface.
* src/gdbm.h.in (GDBM_OPENMASK): New constant.
* src/gdbmconst.h: Remove constants duplicated in
gdbm.h.in.
* src/gdbmdefs.h (gdbm_file_info) <allow_mmap>
<mmap_inited>: Replace with a single member: memory_mapping.
All callers updated.
(GDBM_SETCACHESIZE,GDBM_SETSYNCMODE)
(GDBM_SETCENTFREE,GDBM_SETCOALESCEBLKS): New option names.
(GDBM_SETMMAP,GDBM_GETMMAP,GDBM_GETFLAGS)
(GDBM_GETCACHESIZE,GDBM_GETSYNCMODE,GDBM_GETCENTFREE)
(GDBM_GETCOALESCEBLKS,GDBM_GETMAXMAPSIZE): New option codes.
* src/gdbmsetopt.c: Implement new options.
* doc/gdbm.texinfo: Document new options.
