Zygo Blaxell 4aa5978a89 hash: reduce mutex contention using one mutex per hash table extent ...

This avoids PERFORMANCE warnings when large hash tables are used on slow
CPUs or with lots of worker threads.  It also simplifies the code (no
locksets, only one object-wide mutex instead of two).

Fixed a few minor bugs along the way (e.g. we were not setting the dirty
flag on the right hash table extent when we detected hash table errors).

Simplified error handling:  IO errors on the hash table are ignored,
instead of throwing an exception into the function that tried to use the
hash table.
