afs: Provide mount-time configurable byte-range file locking emulation
Provide byte-range file locking emulation that can be configured at mount
time to one of four modes:
(1) flock=local. Locking is done locally only and no reference is made to
the server.
(2) flock=openafs. Byte-range locking is done locally only; whole-file
locking is done with reference to the server. Whole-file locks cannot
be upgraded unless the client holds an exclusive lock.
(3) flock=strict. Byte-range and whole-file locking both require a
sufficient whole-file lock on the server.
(4) flock=write. As strict, but the client always gets an exclusive
whole-file lock on the server.
