rG9e644c23000c: tcp: add support for TCP over UDP
Summary

Encapsulating TCP over UDP allows the support of peers which implement TCP in userland without requiring special permissions by encapsulating the TCP segments in UDP.

Support for this is already available in Wireshark, packetdrill, and uperf.

It is planned to merge this to the main tree, after FreeBSD 13.0 has been released. This is joint work with rrs@.

Test Plan

Ensure that the corresponding test suite, which is available in the TCP-over-UDP branch of tcp-testsuite.
