xfrm: add espintcp (RFC 8229)
TCP encapsulation of IKE and IPsec messages (RFC 8229) is implemented
as a TCP ULP, overriding in particular the sendmsg and recvmsg
operations. A Stream Parser is used to extract messages out of the TCP
stream using the first 2 bytes as length marker. Received IKE messages
are put on "ike_queue", waiting to be dequeued by the custom recvmsg
implementation. Received ESP messages are sent to XFRM, like with UDP
encapsulation.

Some of this code is taken from the original submission by Herbert
Xu. Currently, only IPv4 is supported, like for UDP encapsulation.
