Message:

Major addition to support DNS SRV resolution in PJSIP:

• added DNS asynchronous/caching resolver engine in PJLIB-UTIL (resolver.[hc])
• modified SIP resolver (sip_resolve.c) to properly perform DNS SRV/A resolution when DNS resolution is enabled.
• added dns_test.c in PJSIP-TEST for testing the SIP resolver.
• added nameserver configuration in PJSUA-LIB
• added "--nameserver" option in PJSUA.
• updated project/Makefiles and doxygen documentation.
