Message:

Close #1568:

• Added media change detection based on SDP negotiation result and local codec param settings, the detection result will decide whether the media should be re-initialized after the SDP negotiation.
• Fixed stream to keep the duplicate of codec param for the stream info (was only copying the pointer).
• Introduced macro PJSUA_THIRD_PARTY_STREAM_HAS_GET_INFO & PJSUA_THIRD_PARTY_STREAM_HAS_GET_STAT.
