> Small change to switch Thread-SMR's hash table from ResourceHashtable to KVHashtable
> so that a variable sized hash table is used instead of a fixed size hash table (1031 elements).
> Also refactor common hash table size calculation code into static hash_table_size()
> function and call it from both places.
> 
> Test with Mach5 Tier[1-7] testing.

Daniel D. Daugherty has updated the pull request incrementally with one additional commit since the last revision:

  Rewind and remove the unused hash_table_size calculations; ThreadScanHashtable is now fixed size.
