  Fix evaluating the SIP port from a SIP URI.

Use the new function get_uri_port() to evaluate the port and proto, in a SIP wise manner, form a SIP URI. If port/proto are not explicitly set in the URI, consider the default port for the used transpor proto. If protocol misses, we assume the default protos according to the URI schema.

NOTE: it is completly bogus (and dangerous) to assue 5061 if SIPS schema is used as:
1) SIPS can use used with WSS, which actually has 443 port
2) TLS can pe required via transport param in a SIP schema URI too
