add a hash table mechanism based upon hcreate(3) but one that allows

us to maintain multiple hash tables concurrently.

immediatly start using it to keep track of what directories
we have already created and what CVS dirs we already created so
we do not recreate them when we do not need to.

we will be switching more internals to use this soon.
rejoice for cheaper lookups.
