We have to send byte range locks to the server (by default). In particular
to handle when multiple clients are locking the same file.  With some
help from jra a few years ago, I think the mapping (advisory
to mandatory, when mounted to windows) works about as
well as we can do, and works for most posix apps.  There are some
cases where users have to disable the duplicate lock enforcement
on the client or the reverse (ie stop sending (mandotory) locks
to the server) and so there are mount options to disable these.
