Handle OnPacketSent on the network thread via MediaChannel.

* Adds a OnPacketSent callback to MediaChannel, which matches with
  MediaChannel::NetworkInterface::SendPacket.
* Moves the OnPacketSent handling to the media channel implementations
  (video/voice) and removes the PeerConnection/SdpOfferAnswerHandler
  layer from the call path.
* Call::OnSentPacket is called directly from the channels on the network
  thread. This eliminates a PostTask to the worker thread for every
  audio/video network packet.
* Remove sigslot dependency from MediaChannel (and derived).
