- if hiddenPremeetingButtons is undefined, toolbarButtons overwrite decides what buttons to show
- if hiddenPremeetingButtons is empty array, all buttons are show on premeeting screen regardless of toolbarButtons
- if hiddenPremeetingButtons hides some buttons, only those buttons will be hidden regardless of toolbarButtons overwrite

If last N goes down to 1 it will be stuck there since it's > 0 and will
be our `lastNSelected`. When limits are applied we'll take the minimum,
so it will end up being 1.

Once can end up in last N being 1 by several means, the more obvious one
by entering Picture-in-Picture mode on mobile.

Fix it by not using the previous last N value for the current
calculation, at all.

Closes: https://github.com/jitsi/jitsi-meet/pull/10491

Fixes screensharing selection issues. Now when there’s a screen share we just use the old VERTICAL_FILMSTRIP_VIEW layout
Add THUMBAIL_TYPE to determine how to display thumbnails

In case of conference failed as max number of occupants reached, we should skip clearing the local tracks to keep state of pre-join screen. Otherwise, on join we will join muted even though on prejoin screen it was unmuted on the initial attempt.

Fixed issue on DialogPortal where the content would flash to the initial position then move to the correct position

Needed to revive the lobby tests.

This reverts commit 6085220bfc.

* code review

* fix: Drop duplicate call of wait for owner.

* fix: Fixes leaking listeners while waiting for host to join.

While waiting for the host to join on the dialog we attempt to join over and over again till we are admitted to enter the meeting. While doing that authRequired flag is on, and we were adding listeners on and on.

* feat: Introduces conference join in progress action.

This event is coming from lib-jitsi-meet and is fired when we receive the first presence of series when joining. It is always fired before joined event.

Fixes issue where the menu would disappear on dominant speaker change

We used to have a registry which registered a single handlerwith RN.
THis was registered really early in the app.

When React Navigation was introduced we ddidn't realize it interacts
with the back button. In a stack nagigator it will navigate to the
previous screen. This meant our back button handling was broken.

This commit removes our previous registry and uses the RN back button
handler directly in the 2 components that use it: the conference and
bottom sheets.

Since these handlers are registered after navigation, our handlers are
going to run first so we cna implement the behavior we need, namely to
dismiss an open botom sheet or set the conference in PiP mode.

See multiple participants on stage
Pin and unpin to stage
Automatic selection of participants to be displayed on the stage filmstrip based on dominant speaker changes
Make Filmstrip a reusable component. Used by MainFilmstrip (old functionality) and the new StageFilmstrip

* add(highlight): mobile initial flow

* fix(hightlight): get meeting fqn on mobile

* fix(dynamic-branding): extract fqn on mobile

* fix(highlights): remove local fqn extraction and grounp dispatches in batch

* fix(dynamic-branding): check if state is defined in extract fqn

Converted LoadConfigOverlay to a JitsiScreen component that right now is part of navigation as ConnectingPage, plus I
separated appNative and other actions into web and native.

* feat(multi-stream-support) Add screenshare as a second video track to the call.
This feature is behind a sendMultipleVideoStreams config.js flag. sourceNameSignaling flag also needs to enabled. Sending multiple tracks is currently supported only on endpoints running in unified plan mode. However, clients with source-name signaling enabled and running in plan-b can still receive multiple streams .

* squash: check if there is an existing track before adding camera/desktop

* squash: enable multi-stream only on unified plan endpoints.

Now the algorithm that calculates the
rows/columns/thumbnail-width/thumbnail-height configuration will
go trough all possible configurations and will choose the one
that covers with thumbnails the biggest area of the window.
