Previously simplehash.h only exposed a method to perform a hash table delete using the hash table key. This meant that the delete function had to perform a hash lookup in order to find the entry to delete. Here we add a new function so that users of simplehash.h can perform a hash delete directly using the entry pointer, thus saving the hash lookup. An upcoming patch that uses simplehash.h already has performed the hash lookup so already has the entry pointer. This change will allow the code in that patch to perform the hash delete without the code in simplehash.h having to perform an additional hash lookup.
