Ian Rogers 0650b2b2e6 perf sharded_mutex: Introduce sharded_mutex 
Per object mutexes may come with significant memory cost while a
global mutex can suffer from unnecessary contention. A sharded mutex
is a compromise where objects are hashed and then a particular mutex
for the hash of the object used. Contention can be controlled by the
number of shards.

v2. Use hashmap.h's hash_bits in case of contention from alignment of
    objects.
