Removed prior audit proof logic - audit proof support was implemented using the generic TLS extension API Tests exercising the new supplemental data registration and callback api can be found in ssltest.c. Implemented changes to s_server and s_client to exercise supplemental data callbacks via the -auth argument, as well as additional flags to exercise supplemental data being sent only during renegotiation.
