Finish up lock.c, adding error checking to see if a lock failed because it's
already locked. Also added gdbm_locked() to the API.
* src/lock.c: Check errno to see if a lock failed because it's already
locked. Add external gdbm_locked() routine to return the
status of locking. Move lock type to the dbf.
* src/gdbmdefs.h: Move lock type to the dbf.
* src/gdbm.proto: Add gdbm_export(), gdbm_import(), and gdbm_locked().
