This series addresses a serious issue in MPTCP option parsing.

This is bigger than the usual -net change, but I was unable to find a
working, sane, smaller fix.

The core change is inside patch 2/5 which moved MPTCP options parsing from
the TCP code inside existing MPTCP hooks and clean MPTCP options status on
each processed packet.

The patch 1/5 is a needed pre-requisite, and patches 3,4,5 are smaller,
related fixes.

v1 -> v2:
 - cleaned-up patch 1/5
 - rebased on top of current -net

Series applied, thanks.
