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.

Test Plan

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