flow: New FLOW_WC_SEQ build assertion.
Changing "struct flow" or its wildcards requires minor adjustments
in many places in the code. This patch adds a new FLOW_WC_SEQ
sequence number which when incremented will cause build assertion
failures aiding the developer in finding code which needs to
change.
