Data channel messages are expected to be sent only to peer connections
with "video" type, which provide the audio and video tracks of the
participant (and, in fact, peer connections for screen shares do not
even have data channels enabled in the WebUI).
Note that this could change if at some point several audio/video tracks
are sent in the same peer connection, or if "speaking" messages are
added to screen shares, but that will be addressed if/when that happens.

For now it just provides support for sending a data channel message to
all participants, so notifying all participants when the media is
toggled or the speaking status change can be directly refactored to use
it.
While it would have been fine to use a single class for both MCU and no
MCU they were split for easier and cleaner unit testing in future
stages.

Starting with Talk 20 the signaling messages that provide updates to the
participants ("participants->update" in the external signaling server,
"usersInRoom" in the internal signaling server) now include "actorType"
and "actorId" properties for each participant.

The CallParticipantModel observer now also emits one-time events that
are not reflected in the model state.

Note the slight difference in naming between the signaling message
("raiseHand", the action) and the stored data ("RaisedHand", the record
of the action).

For now only the same signaling messages that were already handled are
still handled; in the future it could be extended to handle other
messages, like the one sent by the external signaling server when a
participant leaves the room (in some cases no participants update
message is sent if the participant leaves the call and room at the same
time, which causes the participants to still be seen as in call until a
new update is received).
