Make sure errno is preserved, if it can contain details about the gdbm error.
* src/gdbmdefs.h (SAVE_ERRNO): New macro.
* src/gdbmopen.c: Use SAVE_ERRNO where it is important to
preserve system errno.
* src/mmap.c: Likewise.
* doc/gdbm.texinfo: Document which gdbm errors can
be detailed by inspecting the system errno.
