Implement a new basic locking mechanism for GDBM. Add _gdbm_lock_file() and
_gdbm_unlock_file(), which will try to use flock(), lockf(), and fcntl() to
lock the file.
From ChangeLog:
* configure.ac: Add test for lockf.
* src/lock.c: New file, adds _gdbm_unlock_file() and
_gdbm_lock_file() routines. These attempt to use flock(),
lockf(), and fcntl() locking.
* src/proto.h: Add new prototypes.
* src/systems.h: Remove file locking macros.
* src/gdbmopen.c: Rewrite locking code, use _gdbm_lock_file().
* src/gdbmclose.c, src/gdbmreorg.c: Use _gdbm_unlock_file().
