fix(analytics): Remove annoying console.warn.

fix(JitsiConference.leave): reject in case of a timeout

JitsiConference shouldn't lie that the leave() was successful when it
was not.

* 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.

When cancelling the prompt to install the extension, instead of
treating it as a generic error treat is as the cancel extension
error. This allows existing logic to trigger that will not show
an error message on cancel.

* 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

Will emit CONNECTION_ESTABLISHED event to fill up the gap where the lib
users are not able to tell whether or not the connection has been
established if there were no interrupted/restored events emitted.

Enables RTPStatsCollector for react-native. The getStats method was
supported long time ago, but the stats produced by the RTPStatsCollector
were not consumed. Now they are needed for the automated testing on RN.

* Switches camera id to mandatory when using old gum flow.

When it fails we retry with different resolutions, and if that doesn't work we remove device id and let gum to decide which device to use.

* Fixes comments.

feat: enableTcc, enableRemb, minParticipants.

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

fix(JitsiConferenceEvents): typo in KICKED

* remove unused 'show' field

* extract and emit identity information from presence

also replaces some uses of jquery

* combine eslint-disable lines

* refactor packet2JSON to not use jquery

also added unit tests for it and switched to use chrome-headless instead
of phantomjs

* update package-lock

* squash: undo sha512 to sha1 conversion in package-lock

* fix(edge): get p2p working up to ice failure

Edge does not support trickle ice. In an attempt to work around
such, and get p2p working, some other work was needed to even
get to the point of ice failure. This is that some other work.

* squash: fix typos, no intermediary map

* squash: remove extra line break

After running `npm install` I end up with a minified library for lib-jitsi-meet. I had to adjust the name to get the example to run

3478 is default for TURN, but not for TURNS. Reported by @damencho.

Implements the promised based getStats. Enables them for Safari and FF.

Solves a GitHub warning about a vulnerability in a
uglifyjs-webpack-plugin dependency.

Adds stats and audio levels for Safari. Enables the new getStats API for Firefox, that will get rid of the following warning:
'non-maplike pc.getStats access is deprecated, and will be removed in the near future! See http://w3c.github.io/webrtc-pc/#getstats-example for usage.'

feat: Adds a config.gatherStats parameter.

This PR exposes the functionality that's already built-in the
TraceablePeerConnection that has it gather stats from the wrapped
PeerConnection.

This reverts commit 1c2c63e656.
The logging was initially added to help debug an issue with
connection quality showing lower than expected. The usefulness
of the logging has diminished and is noisy for browsers that
do not automatically filter console.debug, like Edge.

* fix(SS): Set min and max frame rate to 5

* fix(SS): Set min and max frame rate for the new GUM flow.

* feat(ss_framerate): Add config option for min/max frame rate.

* doc(RTCUtils): Fix params format.

* fix(SS_framerate): Don't pass undefined constraints.

* fix(SS_constraints): Handle  chromeMediaSourceId === undefined.

* ref(gum): try to reduce complexity of obtainAudioAndVideoPermissions

Even though I walk through the valley of the shadow of death
I will fear no evil... Reduce indenting and repeated calls to
getting desktop streams by creating a promise chain.

* squash: use arrow func

* squash: move constructor support to helper

* squash: put ff into mediastream constructor check

* squash: ff support media stream constructor

MDN states its been supported since 44. ESR is currently
52.

* squash: rename dsoptions, constant defaults

* squash: move comment about missing tracks error handling

* squash: wrap getUserMediaWithConstraints in promise

* squash: split up av funcs

* squash: hey, some tests...are better than no tests?

* log: Logs when analytics are disposed, drops events early.

* fix: Adds a missing parameter to a function call.

ref(browser): Use js-utils.

* fix(connection-quality): set min percentage when exceeding a bitrate threshold

In some cases a high bitrate does not equate to a high quality
percentage, because the target itself might be quite high, such
as the case for 1080. In those cases, give credit for the bitrate
being high.

* squash: impl 2, use a max bitrate

* Adds new parameter details for the connection failed event.

Adds suspend and shard_changed details.

* Updates the used strophejs version in dependencies.

* Updates the used strophejs version in dependencies (package-lock file).

* Changes to always report suspend time, reports 0 on no suspend detected.

* Changes details field name.

Add private messages feature
