RBTree Insert and Find Hooks

This patch introduces user-defined functions (hooks) for inserting and finding
nodes in a red-black tree. These hooks allow the user to implement efficient
insert and find operations with the overhead of a function call indirection
just once per operation, rather than once per level of the tree as with the
previous implementation using the compare function.  A typedef is provided for
both score and sapi to register the hooks.

Future changes may add hooks to other red-black tree functions to support
user-extensions in case a user wants to allow duplicate keys.
