Fix up:port af, use a different var, because utm port af is always AF_INET, and it breaks the target address af if the listening address is AF_INET6
Enable -O2 C flag, because LibreSSL is compiled with -O2 too
Refactor and unify ssl_tls_clienthello_identify() and the earlier
ssl_tls_clienthello_parse_sni() into a single
ssl_tls_clienthello_parse() function that handles parsing ClientHello
messages for different purposes. As a result, rename the debug knob
DEBUG_SNI_PARSER into DEBUG_CLIENTHELLO_PARSER.
