Instead of having visible and visibility and setToolboxVisible and
setFilmstripVisibility, have only visible as a name.

If the view gets resized to a 1:1 aspect ratio, remember the previous mode to
avoid flickering when going back to a larger size or different aspect ratio.

Add URL validation and larger distance behind the back button

The current notification for starting muted is 2 minutes, which
may seem like "forever" so reduce it to dismiss faster.

If config.enableUserRolesBasedOnToken is true, only let moderators
and non-guests modify the password. Otherwise, only let moderators
edit the password.

fix(recommended-browsers): Fix link

chore(lib-jitsi-meet): Update the version.

Load all of them as imports, so the packager includes them in the bundle. Then
register them with the i18next library.

feat: Sets the "product" field in the analytics handler constructor.

fix(lib-jitsi-meet): RTCBrowserType -> browser.

feat(api): expose a way to submit feedback

Spot will need a way to submit call feedback using the iframe
api. For now expose a method on conference.js to submit that
feedback. Exposing on conference.js looks to be the existing
pattern... Also add an event to notify consumers of the iframe
api that feedback was submitted, as postMessage is async
and the notification can at least give some guarantee maybe.

I haven't updated documentation yet as I'm not confident
about this api.

Improve the experience when joining a room by removing the need to tap the join
button. The keyboard type has also been set to "go", which translated on the
builtin keyboard button label to be "go" (it's builtin, the operating system
translates it). This works on both Android and iOS.

Android uses a SurfaceView to render video, which is not quite a View, so the
fade-in animation (which varies the opacity) doesn't work.

Instead, add an opaque black view covering the video, which transitions to
transparent. This creates much smoother transitions on Android, while behaving
the same.

In addition, I removed the flip animation for local tracks, which is no longer
used, since the camera is switched without changing tracks.

It was recently introduced in WebRTC, so we we need to enable it project wide.
