Put the code to print the details of a publisher into a JSON into a
separate function so that it can be reused.

Use a callback function to populate the internal JSON fields. This makes
it possible to reuse this function for other, similar notifications.

We want to send the notification to each publisher's own session, and
not to the session of the originating event.

Distinguish between two cases: Sending a message to one particular WS or
HTTP connection directly as a response to a request, and sending an
asynchronous message or event to a session. Introduce
janus_send_json_sync_response() to do the format, and update all event
notifications to use janus_send_json_async().

We only support websocket-connected Janus sessions for now, and don't
support the HTTP polling mechanism.
Change-Id: Ia4160deeb02db20ed819864fe35f45de14c47ed8
As multiple handles from multiple different sessions can participate in
the same room, we need a way to look up handles from different sessions.
We therefore transfer ownership of all janus_handle objects to global
level. As these are currently not reference-counted, this necessitates
holding the global lock for the entirety of the signalling process.

Janus rooms are not necessarily tied to just a single session. Make it
possible for one room to be used from multiple sessions.
Change-Id: Id35db2ada66a5bf392ce577cb5f2a970ca13b9dc
Avoid calling lws_write() from threads other than the service thread, as
this might not be thread-safe. Instead store the values used for the
HTTP response headers in the websocket_output, then trigger a "writable"
callback, and finally do all the lws_write() calls from the service
thread.

... so that the publishing session gets notified about "webrtcup" and
not the session which created the room.

Our own Janus WS client would create a single WS session and then create
all rooms under this one session and run all publishes and subscribers
under the same session. This is not a restiction imposed by Janus
though, which allows participation in one room by multiple sessions.
Remove this restriction to more closely mirror Janus behaviour.

Apparently Janus allows a single handle to be both controller and
publisher, and possibly also both publisher and subscriber. Remove the
limitation that forces one handle to only take one role.

Make sure janus_session lock is obtained first and websocket_conn lock
second, in order to prevent a possible deadlock.

This isn't really necessary as at this point the janus_session object is
private to the thread, but we add the locking anyway to silence the
warning.
