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).

CallParticipant provides a read-only CallParticipantModel and internally
handles the data channel and peer connection events that modify the
model. Nevertheless, the CallParticipant requires certain properties to
be externally set, like the userId or the peer connections.

Clients that modify the model would define the variables using the
mutable subclass, while clients that only need to access the model are
expected to use the read-only base class.
The read-only class provides an observer; as it is expected that the
model will be modified from background threads but observed from the
main thread the observer can be registered along a handler to be
notified on its thread, independently of on which thread the values were
set.
Currently there does not seem to be a need to observe each value on its
own, so the observer is notified in a coarse way when any value changes.
