* refactored registry operations some. subkey lists and
registry values are now passed around in containers
(REGSUBKEY_CTR & REGVAL_CTR) which each possess a TALLOC_CTX.
* removed subkey_specific_fn() from REGISTRY_OPS. Is implemented
in the form of a wrapper
* temporarily broke the printing registry ops.
* implemented inheritence for the data_p of nodes in a SORTED_TREE
* All REGISTRY_KEY instances now store a valid REGISTRY_HOOK since
the default REGOSTRY_OPS structure is stored in the root of the
cache_tree.
* Probably some other change I forgot.... T
