Bwrosers have not allowerd WebRTC on non-secure origins for a very long time
now.

Add methods for start/stop recording in addition to the commands that we already have.

Get the existing HTMLVideoElement for large video instead of creating a new video element for capturing the screenshot.
This should prevent the video player from getting displayed on mobile Safari.

* Update API documentation

* Remove unneeded whitespace

Starting from version 74, firefox need to be explicitly allowed to capture the screen from an iframe for screensharing. This new Feature-Policy is called "display-capture".

* Adds an option to set email through iframe API init and to stats.

* Simplifies configuring email and displayName in stats.

Removes enableStatsID as not needed as when off we are sending as callstats id xmpp resource which is unique per call and id must be something that sticks between calls (callstatsUsername).

* Adds email and displayName in stats config for mobile.

* chore(deps): Updates lib-jitsi-meet to latest dd31f0a.

* Removes enableStatsID from config and whitelist.

This is for other applications to use, and it's currently only used for logging
1 line, so use console.error.

* Get participant specific video element

We now have the ability to select the video element for specific participants. I'm tweaking the jitsi-meet-electron app for my use case. I need to open Always On Top windows for specific participants, so the current _getLargeVideo() wont suffice.

I made a post about this in the Developers section on the Jitsi Community Forum, but it got blocked by Akismet.

* Add dots at end of sentence.

* Fixed ESlint errors and add additional check for iframe.

* Use _myUserID instead of string.

* Return the local video by default if participantId is undefined.

* Fixed mistake in string template.

  a mic or camera error has occurred
- Use middleware to respond to those notifications
  of errors by showing in-app notifications and
  notifying the external api

Adds a new event fired when Jitsi Meet shows the feedback prompt.
