* feat(recording): add sounds for when recording starts and stops

* squash: use constants, play sounds for file only

* squash: rename recordingStopped.mp3 -> recordingOff.mp3

* squash: flip var declaration for alpha order

* 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

- Update font files to add new icon.
- Update markup and style so the icon has a small background
  to fill in the text of the icon.
- Remove some css transitions that don't seem to do much.

* feat(recording): show the YouTube live stream URL

- From the start live stream dialog, push up the broadcast ID
  of the chosen broadcast. It is assumed the ID can be used to
  create the YouTube link.
- Listen for lib-jitsi-meet to emit updates of the known live
  stream URL, shove it into redux, and have InfoDialog display
  it.

* ref(info): pass in dial in and live stream url

Passing these values in should trigger AtlasKit InlineDialog
to re-render and reposition itself.

* ref(info): use conference existence as trigger for autoshowing dialog

* feat(info): add live stream link to invite copy

* Revert "ref(info): use conference existence as trigger for autoshowing dialog"

This reverts commit 1072102267.

* hidden -> url

* _onClickHiddenURL -> _onClickURLText

* fix(recording): fetch events also for available broadcasts

Only "persistent" broadcasts were being fetched using the
YouTube API. Fetching "all" will get persistent broadcasts
and events. If events use a custom encoder then the stream
key can be obtained. If google hangouts is used for the event
then a stream key will not be obtainable; in those cases
input empty string as the stream key.

* squash: fix typos, reword comments, use object for preventing duplicate broadcasts

* feat(recording): use google api to get stream key

* squash: renaming pass

* squash: return full load promise

* sqush: use google api state enum

* squash: workaround for lib not loading

* another new design...

* increase timeout workaround for gapi load issue

* styling pass

* tweak copy

* squash: auto select first broadcast

* WiP(invite-ui): Initial move of invite UI to invite button

* Adjusts styling to fit both horizontal and vertical filmstrip

* Removes comment and functions not needed

* [squash] Addressing various review comments

* [squash] Move invite options to a separate config

* [squash] Adjust invite button styles until we fix the whole UI theme

* [squash] Fix the remote videos scroll

* [squash]:Do not show popup menu when 1 option is available

* [squash]: Disable the invite button in filmstrip mode

* feat(connection-indicator): implement automatic hiding on good connection (#2009)

* ref(connection-stats): use PropTypes package

* feat(connection-stats): display a summary of the connection quality

* feat(connection-indicator): show empty bars for interrupted connection

* feat(connection-indicator): change background color based on status

* feat(connection-indicator): implement automatic hiding on good connection

* fix(connection-indicator): explicitly set font size

Currently non-react code will set an icon size on ConnectionIndicator.
This doesn't work on initial call join in vertical filmstrip after
some changes to support hiding the indicator. The chosen fix is
passing in the icon size to mirror what would happe with full
filmstrip reactification.

* ref(connection-stats): rename statuses

* feat(connection-indicator): make hiding behavior configurable

The original implementation made the auto hiding of the indicator
configured in interfaceConfig.

* fix(connection-indicator): readd class expected by torture tests

* fix(connection-indicator): change connection quality display styling

Bold the connection summary in the stats popover so it stands out.
Change the summaries so there are only three--strong, nonoptimal,
poor.

* fix(connection-indicator): gray background on lost connection

* feat(icons): add new gsm bars icon

* feat(connection-indicator): use new 3-bar icon

* ref(icons): remove icon-connection and icon-connection-lost

Both have been replaced by icon-gsm-bars so they are not
being referenced anymore. Mobile looks to have connect-lost
as a separate icon in font-icons/jitsi.json.

* fix(defaultToolbarButtons): Fixes unresolved InfoDialogButton component problem

* [squash]: Makes invite button fit the container

* [squash]:Addressing invite truncate, remote menu position and comment

* [squash]:Fix z-index in horizontal mode, z-index in lonely call

* [squash]: Fix filmstripOnly property, remove important from css

Prepare for React 16.

* ref(1-on-1): move remote visibility to a selector

Derive whether or not remote videos should display using a selector
to look across different states. A selector was chosen over using
memoized selectors (reselect) or subscribers as a first step
approach, avoiding additional mutations caused by a subscriber
updating the filmstrip state and avoiding additional api overhead
introduced by reselect.

* rename selector

* ref(recording): convert recording label to react

- Create a RecordingLabel component for displaying the current
  recording state, as reflected in the redux store. This is
  needed for 1-on-1 mode to be completely in redux.
- Update the store with the recording state so RecordingLabel
  can update itself.
- Remove previous logic for updating the non-react label, which
  includes event emitting for filmstrip visibility changes,
  as RecordingLabel is hooked into redux updates.

* ref(recording): use status and type constants from lib

* make label really dumb, move logic back to Recording
