Re #1623: fixed deadlock between conference mutex and ICE. Scenario:

  • sound device thread calls put_frame() which gets the conf mutex, and is calling transport sendto() to send RTP packet which requires ICE mutex.
  • The worker thread finished ICE negotiation and notifies PJSUA-LIB and application while holding ICE group lock, app then do conf_connect() which causes deadlock.

This fix defer the callback to a timer.
