* Update reference to Prosody bugtracker.

* Updated refernce to Prosody module.

* Remove unused child element.

The child element in the query suggests that a specific host is being requested. Neither
the Prosody implementation nor the XEP-0215 specification defines this element. Its
inclusion is ignored by the XEP-0215 server implementation.

When receiving presence, the XML is converted to JSON. In
the process, Strophe.getText is used, which calls its
xmlescape utility function. This is not desired as the
raw value is desired, especially for display name.

Note: this issue only affects presence as it is the only
place that call the helper packet2JSON, which is the only
place that calls Strophe.getText.

* ref(recording): change implementation to match VideoSIPGW

VideoSIPGW takes in a chat room and uses instance variables
on the chat room. RecordingManager has been changed to
mirror this approach because of the case where jitsi is
deployed on a domain requiring authentication. In that
case, the initial chat room is created and fails, a
new chat room (connection) is created for authentication,
authentication is put onto the failed chat room, and the
failed chat room is used. As such, recordingManager
should not be tied to chat room creation itself but
rather tied to the first chat room.

* squash: use git mv to detect capitalization change

* feat(recording): frontend logic can support live streaming and recording

Instead of either live streaming or recording, now both can live together.
The changes to facilitate such include the following:
- Remove the old recording.js module which allowed one recording at a time.
- Remove events for live stream url changes as the url is now part of a
  sesssion and not fired independently.
- Availability of sipgw and recording are gone. Instead sessions have a
  failure reason. For sipgw sessions, store that failure and emit it to
  listeners.
- Create a new recordingManager singleton that can start/stop sessions
  and handle updating known state of those sessions. Known state is
  emitted through one event.
- Create a JibriSession model to encapsulate state of a session.

* update comments, use map to store sessions

* always pass in focusmucjid

* try to fix jibrisession docs and remove default null

* feat: Exposes sending JSON payload through XMPP.

Incudes only the payload when firing events for JSON trannsported
through XMPP.

* squash: Addresses feedback.

* squash: Addresses more feedback.

* feat(recording): show the YouTube live stream URL

- Pass you_tube_broadcast_id to Jibri so it can create a
  YouTube link for the live stream.
- Emit the liveStreamViewURL (the YouTube link) when it
  is received from the participant doing the recording.

* set member.liveStreamViewURL only when truthy

react-native does not support querySelectorAll. jitsi-meet's
react-native does have a polyfill for querySelector so use
that instead.

ESLint 4.8.0 discovers a lot of error related to formatting. While I
tried to fix as many of them as possible, a portion of them actually go
against our coding style. In such a case, I've disabled the indent rule
which effectively leaves it as it was before ESLint 4.8.0.

In case there was a status message and later that message is removed from the presence, fire an event so the UI can also clear it.

via JSON messages received via the Chatroom

If we detect a custom <ignore tag in presence unavailable we ignore those presences and do not process them.

* ref: Moves the deployment info variables to config.js

instead of using globals.

* feat: If configured, adds the user's region to presence.

* fix: Guards against accessing undefined properties,

and uses the crossRegion variable from the config.

* style: Fixes formatting.

Sending the bare jid, speeds call setup as otherwise jigasi needs to do a feature discovery finding the conference component address and use it to construct the room address to join.

Audio SSRC needs to stay consistent between detach and attach operations

There are problems with going back from P2P to JVB in FireFox. Other
participants will not see FF video. Looks like something related to
