Wait until the right button size has been calculated before rendering it.

- add 10px of padding on the sizes of the toolbar
- make the button margin smaller (from 10 to 7)
- increate the secondary button factor to 85%, thus rising the maximum secondary
  button size to 50 (from the previous 48)

Doing so in CONFERENCE_JOINED is too late because if we are moderators that
event will come first and we won't know what ID to match it with.

This is safe because our local ID is created early.

Show it if we are the only participant, and hide it the moment someone else
joins the conference.

- 5 buttons in the (now single) toolbar
- Overflow menu in the form of a BottomSheet
- Filmstrip on the right when in wide mode

* fix(PresenceLabel): Use translated strings for the presence label.

* feat(sounds): Implements loop and stop functionality.

* feat(invite): Add ringtones.

* fix(invite): Code style issues.

* feat(recording): frontend logic can support live streaming and recording

Instead of either live streaming or recording, now both can live together. The
changes to facilitate such include the following:
- Killing the state storing in Recording.js. Instead state is stored in the lib
  and updated in redux for labels to display the necessary state updates.
- Creating a new container, Labels, for recording labels. Previously labels were
  manually created and positioned. The container can create a reasonable number
  of labels and only the container itself needs to be positioned with CSS. The
  VideoQualityLabel has been shoved into the container as well because it moves
  along with the recording labels.
- The action for updating recording state has been modified to enable updating
  an array of recording sessions to support having multiple sessions.
- Confirmation dialogs for stopping and starting a file recording session have
  been created, as they previously were jquery modals opened by Recording.js.
- Toolbox.web displays live streaming and recording buttons based on
  configuration instead of recording availability.
- VideoQualityLabel and RecordingLabel have been simplified to remove any
  positioning logic, as the Labels container handles such.
- Previous recording state update logic has been moved into the RecordingLabel
  component. Each RecordingLabel is in charge of displaying state for a
  recording session. The display UX has been left alone.
- Sipgw availability is no longer broadcast so remove logic depending on its
  state. Some moving around of code was necessary to get around linting errors
  about the existing code being too deeply nested (even though I didn't touch
  it).

* work around lib-jitsi-meet circular dependency issues

* refactor labels to use html base

* pass in translation keys to video quality label

* add video quality classnames for torture tests

* break up, rearrange recorder session update listener

* add comment about disabling startup resize animation

* rename session to sessionData

* chore(deps): update to latest lib for recording changes

I don't think it's realistic that we'd merge a PR that breaks the most
important shortcuts of the app (in my opinion): audio and video
mute/unmute.

Contributing all buttons in one place goes against the designs that we
set out at the beginning of the project's rewrite and that multiple of
us have been following since then.

Technically we still depend on interfaceConfig, but this paves the way for when
that is no longer the case.

Create standalone components for each feature and move all state to them.
Toolbars are now dummy containers.

- Move the toolbar to the filmstrip feature
- Use all the buttons from the toolbox feature

Only on web, since there is currently no equivalent on mobile. It encapsulates
all funcionality related to opening the settings dialog / panel.

Use the new abstractions, which already take care of the rendering part.

Currently the following are implemented:

- AudioMuteButton
- HangupButton
- VideoMuteButton

In order to implement these new buttons a new abstract class was introduced,
which abstracts the ToolboxItem into a button with enough hooks so a stateful
and a stateless version of it can be created.

This patch only adds the stateful implementation of the aforementioned buttons.

This abstraction represents an action which can go anywhere in a toolbox (be
that the main toolbar or the overflow menu) and it's platform independent.

It does not depend on Redux, thus making it stateless, which facilitates its use
in stateful button implementations as well as stateless ones.

One has to be explicit on iOS, otherwise it seems to be locked to portrait only.

Knowledge is power, man!

The config.js cache predates the feature base/known-domains.
Technically, it's also able to recall more domains that the feature
recent-list can (because the latter limits its entries).

Knowledge is power, man!

We moved "knownDomains" from calendar-sync to base/known-domains.
However, we do have an official release in the app stores and I'd like
us to not throw away the knowledge it has acquired.

If authenticated using JWT, don't show the profile button but
do show it if a guest.

If multiple JitsiMeetView instances are created (not necessarily
existing at once), it's possible to hit a TypeError when reading the
React Component props of the currently mounted App. Anyway, in certain
places we're already protecting against that out of abundance of caution
so it makes no sense to not protect everywhere.

Make it more generic by accepting any content except of just rows with text and
icons.

In addition, rework its structure so the animation is smoother, by putting the
background overlay outside of the Modal. This way, the animation doesn't affect
the background, which won't slide down.
