ocfs2_dlmfs: Use the stackglue.
Rather than directly using o2dlm, dlmfs can now use the stackglue. This
allows it to use userspace cluster stacks and fs/dlm. This commit
forces o2cb for now. A latter commit will bump the protocol version and
allow non-o2cb stacks.
This is one big sed, really. LKM_xxMODE becomes DLM_LOCK_xx. LKM_flag
becomes DLM_LKF_flag.
We also learn to check that the LVB is valid before reading it. Any DLM
can lose the contents of the LVB during a complicated recovery. userdlm
should be checking this. Now it does. dlmfs will return 0 from read(2)
if the LVB was invalid.
