Summary: Check for maddr in nat_uac_test("2")

Initial Comment:
According to rfc3261, the address in the Via-Header may be a hostname, so checking against received address will fail using flag 2 in nat_uac_test(). Additionally, a hop may add an maddr-Parameter to Via where the reply has to be sent to, so if this parameter is present, nat_uac_test("2") should compare the received-address with the value of this parameter if it's present, otherwise with the IP given in Via-Header.

Example:

Via: SIP/2.0/UDP somehostname:5060;maddr=1.2.3.4;branch=z9hG4bK-1234
