Fix #1237, #1238, #1241:
 - Fixed handling remote re-offer, where SDP media line may be added or removed.
 - Fixed bug in receiving remote offer (initial or subsequent), media channel create sdp must consider acc->cfg.max_audio_cnt setting.
 - Fixed bug media transport is not closed after call disconnected.
 - Fixed assertion in lock_codec after receiving initial answer but no acceptable media (in pjsua level, e.g: SRTP nego failed), now the call will be terminated.
