hashtable: drop all non-reentrant versions

The non-reentrant versions of the hashtable functions operate on a single
shared hashtable.  So if two different people try using these funcs for
two different purposes, they'll cause problems for the other.

Avoid this by converting all existing hashtable consumers over to the
reentrant versions and then punting the non-reentrant ones.
