Joel Becker 7431cd7e8d ocfs2: Use -errno instead of dlm_status for ocfs2_dlm_lock/unlock() API. 
Change the ocfs2_dlm_lock/unlock() functions to return -errno values.
This is the first step towards elminiating dlm_status in
fs/ocfs2/dlmglue.c.  The change also passes -errno values to
->unlock_ast().

[ Fix a return code in dlmglue.c and change the error translation table into
  an array of ints. --Mark ]

Joel Becker bd3e76105d ocfs2: Use global DLM_ constants in generic code. 
The ocfs2 generic code should use the values in <linux/dlmconstants.h>.
stackglue.c will convert them to o2dlm values.

Joel Becker 24ef1815e5 ocfs2: Separate out dlm lock functions. 
This is the first in a series of patches to isolate ocfs2 from the
underlying cluster stack. Here we wrap the dlm locking functions with
ocfs2-specific calls. Because ocfs2 always uses the same dlm lock status
callbacks, we can eliminate the callbacks from the filesystem visible
functions.
