* 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.

* 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.

* Updates the used strophejs version in dependencies (1.2.14-1).

* Changes details field name.

lib-jitsi-meet does not get polyfilled for es6 methods.
Using Array.prototype.find will cause breakages in older
browsers, like ie11. The quick fix for now is changing
the find call to be a for-loop. The long term fix will
be discussed soon.

This commit will append "-" + tpc.id to every local 'MSID', 'cname',
'label' and 'mslabel', before feeding the local SDP to the Jingle layer.
It will make stream IDs unique across TraceablePeerConnection instances
and prevent from conflicts in some corner cases.

For example this will fix a problem where if the client drops
the conference without leaving the XMPP MUC gracefully and will join
the conference again without recreating the local tracks it would lead
to the MSID conflict, because the stream is still advertised by
"the ghost" participant.

* fix: Fixes version comparison.

* fix(BrowserCapabilities): Searching for the correct version from capabilitiesDB.

* fix(BrowserDetection): Remove unnecessary checks.

In order to include browser capabilities in RTCBrowserType I needed to
refactor RTCBrowserType.

Avoid throwing an exception if an analytics handler throws one. Emit a warning
though, so the problem can be eventually caught and fixed in the handler.

In Rect Native it will stall the app as it's huge.

jitsi-meet has been changed to have tpc.js on info by default, so these
logs still won't show by default.

Renames to sendEventAndLog, supports the object-based API, uses the
function where appropriate.

* ref: Uses "action" instead of "name".

* ref: Uses underscore in events' attribute names.

* ref: Logs a message to the logger/console

instead of callstats in sendAnalyticsAndLog().

Calling JSON.stringify on a temasys object causes a stack overflow.
The result is that the JingleSessionPC's work queue never gets
cleared so future work, like video muting, will not get called.
Instead of passing in the candidate directly, manually do
what chrome's implementation of candidate.toJSON does.

* 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.

* 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.

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.

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

* 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.
