We now depend on user selectable options rather than
select them. There is no dependancy on SYSFS since this
selection is independant of the DLM (even though it wouldn't
be sensible to build the DLM without it)

This is the core of the distributed lock manager which is required
to use GFS2 as a cluster filesystem. It is also used by CLVM and
can be used as a standalone lock manager independantly of either
of these two projects.
It implements VAX-style locking modes.
