Title: Convert OFStateManager hashtables to BigHash

Reviewer: @ducwindow

Increases flow-add performance in my benchmark by 18%, likely due to autogrow sizing the tables better than we did by hand.

The ft checksum buckets array looks like a hashtable, but it's actually indexed by the upper bits of the cookie, not a hash. That's why it wasn't changed.

Fixes IND-73.
