* Passes getWiFiStatsMethod to callstats.

* Prints WiFi addresses on attachWifiStatsHandler.

* Updates callstats version to 3.27.0.

Strophe's builtin retry mechanism uses exponential backoff, and 5 retries
results in a very long time.

Otherwise, if we never connected, we won't know.

Added descriptions for user identifying information in JWT tokens
Added better descriptions of prosody configuration settings when accepting JWT tokens

* exclude fec-fr secondary ssrcs when looking for primary ssrcs

this was causing us to generate an rtx ssrc for the fec stream

* fix variable

* Updates default gum and peer connection constraints.

* Updates old default gum constraints.

Also, updatee the documentation section on connection errors.

Adds rtc.LOCAL_TRACK_SSRC_UPDATED event to be emitted when ssrc is updated for a local track.
Fixes adding rtc listeners for CREATE_ANSWER_FAILED, CREATE_OFFER_FAILED, SET_LOCAL_DESCRIPTION_FAILED, SET_REMOTE_DESCRIPTION_FAILED.

The error handling block for unsupported resolution can be
skipped because native gum should be doing automatic retries
at lower resolutions and leaving in the handling will only
cause an infinite loop. Analytics for the error still get
sent in the error handling directly below the retry logic.

In case backend was initialized before creating our Callstats instance, we skip calling the callstats method addNewFabric.

* Changes initialization of videoSIPGW.

* Adds some errors returned on creating videoSIPGW session.

* Fixes sending videoSIPGW session STATE_CHANGED event.

* Fixes sending jibriIQ, no result status is received.

* Adds VIDEO_SIP_GW_SESSION_STATE_CHANGED to JitsiConferenceEvents.

* Fixing comments.

If a mute / unmute operation is queued when the track is disposed, fail with an
appropriate error.

* ref: Simplifies the logic for handling an incoming jingle session-initiate.

* fix: Don't redundantly log cross region

information under a field name called "label".

* cleanup: Simplifies code. Adds the userAgent as a permanent property

for statistics (so that the client doesn't have to).

* ref: Names the parameter which specifies the name of the event "eventName".

* ref: Extracts event names to AnalyticsEvents.

* ref: Exports and imports constants individually.

* fix: Fixes CONNECTION_TIMES event names.

* ref: Arranges constants alphabetically.

* ref: Adds line breaks.

This is a two part fix:
- In the new gum flow, this.getUserMedia supports promises
  and rejections were not getting caught. So change
  _newGetUserMediaWithConstraints to be promise based instead
  of callback.
- The error name returned from blocked device permissions is
  NotAllowedError, as adapter shims PermissionDeniedError
  to be NotAllowedError.

When a mac's default audio output is changed, audio elements
are not being updated with the new default. A default audio
output change in the OS fires a DEVICE_LIST_CHANGED event,
so use that to always update the sinkId.

Also, use wrapAttachMediaStream for newGumFlow to be ensure
the proper sinkId is set on audio elements being coupled
a remote track.

Error handling was added to ensure some munging helpers
were receiving RTCSessionDescriptions. Temasys is doing
something else and is passing its own object into
the mungers. So, let temasys do that.

IE11 errors when adding a temasys media stream object to
a Set. So instead use an Array.

AnalyticsAdapter is initialized on file load. The constructor
calls a method that calls Object.assign. All this happens
before jitsi-meet has loaded polyfills. So, instead
initialize permanentProperties inline with the expected
values, avoiding Object.assign.

Safari will fail to set its remote description if no
supported video codecs are found. This can happen with
config.p2p.disableH264 set to true, as browsers will strip
H264 from their offers. To get around this problem in a way
that can be removed once this is fixed on Safari's side,
add a function to inject H265 before setting the remote
description.

* revert: Reverts be665cbff7.

* ref: Renames "peerjid".

* ref: Refactors the initialization of a peer connection.

* feat: Re-implements the A/B test for the "suspend video" feature.

* squash: Deep copy.

* ref: Renames forceSuspendVideo to abtestSuspendVideo.

Ssrcs not grouped together in the jingle element
are not recognized by the bridge. When parsing an
sdp with ssrcs that are not listed consecutively
it is important to still group them together
in the jingle element.

* ref(sdp): lower logs about missing local video to warning

* ref(sdp): earlier error handling for missing description and mlines

* ref(sdp): rename maybeMungeLocalSdp to be more specific

Firefox has deprecated modifying a description's sdp through
re-assignment. Safari (without temasys) does not allow it.
As such, wherever the sdp has to be modified instead create
a new description with the modified sdp.

Upgrade flow to 0.53.0

Required for jitsi-meet upgrade

* feat(adapter): use with firefox

* squash: add comment about sdptransform workaround

- Add a new browser check so adapter shim usage can be gated.
- Get track resolution for stats from the track itself to account
  for browser resolution fallback logic. Do this only if
  we can be sure adapter has shimmed it in.
- Create a new getUserMediaFlow, with RTC being the orchestration
  for various RTCUtils calls.
- Remove connection quality stat "resolution" which was being
  emitted but not used but listeners.

remove invalid test and run tests pre-commit
