Use much bigger hash tables for memory allocations now that we aremame0142u1
allocating lots of small objects. Previous size was scaling poorly
and taking a lot of time to free, causing things like -listxml
and -validate to be a lot slower than before since the new
driver_enumerator actually frees all of its memory at the end.
Also changed resource_pool to support a hash table size as input to
the constructor, which allows the global pool to be large, while
the machine-local pools can remain smaller.
