This is the first RFC version of adding DSS checksum and MP_FAIL support,
addressed issue #134 and #52. It's not finish yet. Patch 1 had a bug in
it. The self test script mptcp_join.sh could pass, but mptcp_connect.sh
will fail sometimes. Patch 2 didn't implement the logic of receiving the
MP_FAIL, where I marked it with a TODO label.
 
I need some suggestions to improve this patchset.

Thanks.
