flow, tcp: Generalise TCP hash table to general flow hash table
Move the data structures and helper functions for the TCP hash table to
flow.c, making it a general hash table indexing sides of flows. This is
largely code motion and straightforward renames. There are two semantic
changes:
* flow_lookup_af() now needs to verify that the entry has a matching
protocol and interface as well as matching addresses and ports.
* We double the size of the hash table, because it's now at least
theoretically possible for both sides of each flow to be hashed.
