flow: Make unified version of flow table compaction

tcp_table_compact() will move entries in the connection/flow table to keep
it compact when other entries are removed.  The moved entries need not have
the same type as the flow removed, so it needs to be able to handle moving
any type of flow.  Therefore, move it to flow.c rather than being
purportedly TCP specific.
