Improve _gdbm_findkey interface.
* doc/gdbm.texi: Document gdbm_exists in detail.
* src/findkey.c (_gdbm_findkey): return parameters can be
NULL.
* src/gdbmexists.c (gdbm_exists): Remove unnecessary
local variables. Reset gdbm_errno to 0 if the key was
not found.
* src/gdbmdelete.c (gdbm_delete): Remove unnecessary
local variables.
* src/gdbmfetch.c: Likewise.
* src/gdbmseq.c: Likewise.
