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().
