[GFS2] Update debugging code
Update the debugging code in trans.c and at the same time improve the debugging code for gfs2_holders. The new code should be pretty fast during the normal case and provide just as much information in case of errors (or more). One small function from glock.c has moved to glock.h as a static inline so that its return address won't get in the way of the debugging. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
