Pull dlm updatesfrom David Teigland:
"This set includes a major redesign of recording the master node for
resources. The old dir hash table, which just held the master node
for each resource, has been removed. The rsb hash table has always
duplicated the master node value from the dir, and is now the single
record of it.
Having two full hash tables of all resources has always been a waste,
especially since one just duplicated a single value from the other.
Local requests will now often require one instead of two lengthy hash
table searches.
The other substantial change is made possible by the dirtbl removal,
and fixes a long standing race between resource removal and lookup by
reworking how removal is done. At the same time it improves the
efficiency of removal by avoiding repeated searches through a hash
bucket.
The other commits include minor fixes and changes."
