To be sure we always report room name in small case and as mobile and jigasi report this way it will take time for them to adopt which leads to wrong stats.

* Adds confID to JitsiConference option and enables callstats siteID.

* Simplifies siteID logic and use '/' as default when there is no tenant.

In TraceablePeerConnection: we're no longer injecting a recvonly SSRC
when the local video track is muted, so it's normal that there is no
SSRC found in the local SDP when it's muted.

About RTPStatsCollector: at the time of adding this log statement a case
was missed when local audio track could be replaced in the P2P
connection when a new audio device is selected.

It should be provided by the environment, just like on web. This avoids bundling
callstats on web, where it won't be used (we dynamically download it).

This reduces the bundle size from about 1MB to 675KB, almost 40%.

Fixes tests.

Updates speakers stats with values received by the spealerstats component, all the logic is activate only in case we discover speakerstats component address from disco-info and the incoming message is coming from that component.

When the main domain advertises component with type 'speakerstats' every participant will send message to the component with the name of the room where this happen.

The 'self.errorCallback' was passed incorrectly - it should have been
bound to 'self' eventually, but now the arrow function is the preferred
way.

There is nothing asynchronous about the initialization process (anymore), thus
turn it into a synchronous method.

In addition, WebRTC support is absolute, it cannot change from not being
supported to being supported (as it plreviously could, thanks to Temasys) so get
rid of the ancillary logic to support that.

Last, introduce a way to check if WebRTC is supported in the current
environment: JitsiMeetJS.isWebRtcSupported().

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.

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.'

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

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

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.

function where appropriate.

* ref: Remove unused functions, adds documentation.

* feat: Adds a Statistics.sendAnalytics shortcut.

* doc: Updates the documentation.

* fix: Fixes adding of permanent properties.

Uses "_" as a separator instead of camel case or ".".

* feat: Adds the conference name as a permanent property automatically.

* ref: Don't expose Setting.machineId.

* fix: Adds a "p2p" attribute to jingle events.

* 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().

* Passes getWiFiStatsMethod to callstats.

* Prints WiFi addresses on attachWifiStatsHandler.

* Updates callstats version to 3.27.0.

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: 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.

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.

* Loads CallStats backend only after the script has finished downloading.

* Updates jsdoc and log level.

* Updates jsdoc.

* Uses optional statsId to report to callstats and push it to presence.

The feature is behind a flag which is disabled by default.

* Renames statsId to statsID.

* Fixes doc.

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.

Because the implementation of LocalStorage in jitsi-meet at the time
of this writing is asynchronous with respect to loading and saving,
delay the generation of machineId in order to allow LocalStorage to
load any previously saved value.

There are whole objects logged and the react-native app would crash when
logging too much stuff.

It's no longer needed, and it hasn't been for a while.

This commit changes the way the average stats are being reported to the
analytics backend. Instead of prefixes for the different scenarios
("p2p_", "jvb121_" and no prefix for multi-party calls) we now have
properties that allow to distinguish which scenario an event pertains
to. The query language of the analytics backend can be used to build
appropriate queries that group by those properties.

Additionally, we now report whether the average stats event concerns a
relayed call (a call that's routed via a TURN server) or not.
