Modified Files:
	src/sys/lib/libkern: rb.c rb.h

Log Message:
Add a way for a user to know what nodes have changed when a node has been
inserted or removed.  Refactor node insertion to not require rebalancing
all the time or a loop if it does.  In rb_tree_swap_prune_and_rebalance,
don't call rb_tree_reparent_nodes, instead do the work ourselves (since
we will eventually undo half of the work of rb_tree_reparent_nodes).
