Namecache revamp.
This eliminates the large single namecache hash table, and implements
the name cache as a global lru of entires, and a redblack tree in each
vnode. It makes cache_purge actually purge the namecache entries associated
with a vnode when a vnode is recycled (very important for later on actually being
able to resize the vnode pool)
This commit does #if 0 out a bunch of procmap code that was
already broken before this change, but needs to be redone completely.
Tested by many, including in thib's nfs test setup.
