Browse Source 
* includes AD in authentication check of TLS records

As per 5.2 of TLS 1.3 draft-28, the additional data is record header.

* tests: Update tests in order to support draft-28

* Interoperability: Updates NSS and BoringSSL versions to the
  one supporting draft-28
* Bogo: Updates revision number to use tests for draft-28
* FIX: makefile was using test-compat target instead of
  test-interop

* DC test: constify

* Use binary interface to encode in big-endian
