Instead of the global hash table with the terrible hashfunction and a
global lock, switch the uvm object pages to being kept in a per-object
RB_TREE. Right now this is approximately the same speed, but cleaner.
When biglock usage is reduced this will improve concurrency due to lock
contention..
ok beck@ art@. Thanks to jasper for the speed testing.
