====================
mptcp: Fixes for address advertisement

Patches 1 and 2 allow address advertisements to be removed without
affecting current connected subflows, and updates associated self tests.

Patches 3 and 4 correctly track (and allow removal of) addresses that
were implicitly announced as part of subflow creation. Also updates
associated self tests.

Patch 5 makes subflow and address announcement counters work consistently
between the userspace and in-kernel path managers.
