Will override email, display name and avatar URL with the values
provided in 'context.user' structure of the JWT token.

Settings will no longer be used to retrieve local display name,
email and avatar URL. Now those values will be obtained from
the /features/base/participants Redux state.

fix(jwt/middleware): use const for default name

fix: wrong default display name on web

ref(base/participants): remove getDisplayName functions

ref(jwt): do not accept unknown user fields

* 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Both have been replaced by icon-gsm-bars so they are not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

- Remove references to the model ContactList.
- Replace ContactListView with an empty element for attaching
  the React Component ContactListPanel, which has the same
  features as the old ContactListView.
- Create new selector for getting non-fake participants for
  ContactListPanel's props.
- Create a ParticipantCounter component to place in the contact
  list button. Previously ContactListView updated that but now
  it's a react component hooked into the participant state.
- Remove pub/sub that was used only by ContactListView.

The local audio stream is attached to an audio element that is
always muted. As such, local audio is not being rendered and
the attaching may just not be needed at all.

The current custom debounce function sets a timeout and ensures
additional calls are not executed while the timeout is pending.
Regulating the call of a function while also ensuring it gets
called at a certain time is a throttle.

* ref: video muted state

Get rid of 'videoMuted' flag in conference.js

* ref: audio muted state

Get rid of 'audioMuted' flag in conference.js

* fix(conference.js|API): early audio/video muted updates

* ref(conference.js): rename isVideoMuted

Rename isVideoMuted to isLocalVideoMuted to be consistent with
isLocalAudioMuted.

* doc|style(conference.js): comments and space after if

* ref: move 'setTrackMuted' to functions

* fix(tracks/middleware): no-lonely-if

* ref(features/toolbox): get rid of last argument

* ref(defaultToolbarButtons): rename var

- Remove non-redux paths for hiding and showing remote videos.
- Hook web filmstrip to redux to know when to hide remote videos.
  This works, even though VideoLayout is handling RemoteVideo
  appending, because react is only monitoring filmstrip's declared
  JSX which does not change except for attributes (css classes).

* feat(small-video): use InlineDialog for stats and remote menu

- Remove JitsiPopover and use InlineDialog instead.
- Bring the remote menu icon into react.
- Make vertical filmstrip position:fixed so popper (AtlasKit
  dependency) sets InlineDialogs and eventually tooltips to
  position:fixed.

* ref(remote-menu): hook KickButton to redux

* ref(remote-menu): hook MuteButton to redux

* modify padding, toggle dialogs

* pixel push margins to align dialogs, adjust padding of dialogs

* add comment about margin for dialog, add file I forgot

* modify indicator markup so the icon can be moved down while trigger stays at top of toolbar

* feat(feedback): convert to react and redux

- For styles, remove "aui-dialog2" nesting so existing styles
  can be reused.
- Remove Feedback.js and replace with calls to redux for state
  storing and accessing.
- Add dispatching to FeedbackButton instead of relying on jquery
  clicking handling so the button can be hooked into redux.

* address feedback

* remove calling to not show feedback for recorder and filmstrip

Create a new component that uses Dialog. Reuse existing actions
for updating a participant's display name.

- Create a notification component for displaying a toggle.
- Create an action for showing the component if allowed by
  the local storage setting and for saving the setting to
  local storage.
- Remove all notifications having a timeout by default so the
  device error notification must be dismissed manually.
- Split the camera and mic error dialog into two separate
  notifications.

* feat(notifications): implement a react/redux notification system

* squash into impl explicit timeout, style

* ref(notifications): convert toastr notifications to use react

* ref(toastr): remove library

* squash into conversion: pass timeout

* squash into clean remove from debian patch

Make toolbar's microphone button enabled whenever there are any
'audioinput' devices available and allow to add audio during
the conference even if microphone permissions were denied on startup.

Instead of passing stats through UI then VideoLayout then the
SmallVideo, pass stats directly to what uses it--ConnectionIndicator.
This also bypasses adding the stats to the store, as they do not
seem to be something that needs to be shared or stored app-wide
just yet.

Will try to use screensharing instead of camera video from
the beginning.

Dynamically enables/disables the toolbar video button. Prior to that
commit if we would start with no video there would be no way to enable
it later on.

* feat(display-name): convert to React

- Create a new React Component for displaying and updating display
  names on small videos
- The updating of the Component is defined in the parent class
  SmallVideo, which children will get access to through prototype
  copying
- Create a new actionType and middleware so name changes that occur
  in DisplayName can be propogated to outside redux
- Update the local video's DisplayName when a conference is joined
  or else the component may keep an undefined user id

* squash: query for the container, not the el owned by react

- Create a new ConnectionIndicator component for displaying an
  icon for connection quality and for triggering a popover. The
  popover handling has been left in ConnectionIndicator for now,
  which follows the existing implementation.
- Remove the unused method "connectionIndicatorShowMore"
- Change the implementation of existing methods that update the
  connection indicator to call the same method which will rerender
  the indicator completely.

Rewrite the non-React RingOverlay into the React Component CallOverlay
in a way which makes it easier to port to React Native.

- Expose an api on Filmstrip to hide the remote videos container, which does so
  by adding a class
- Modify listeners for user join, leave, share video to call the api
- Hide the container when there is 1 or fewer remote participants
- Always show the container if self view is in focus
- Show the container if the number of remote thumbnails does not match the count
  of remote participants, such as the case of sharing a video

- Add a class to the body when in vertical filmstrip mode
- Override styles as necessary to support the mode
- Add an option to make tooltips display from the left
- Move the HD Label to the bottom left
- Move the remote video menu to the bottom left, move the mute
  icons to the bottom right
- Scale the local video's height and width to fit the filmstrip

In its current implementation, the VideoStatusLabel shows HD based on peer
connection stats. These stats will be available on temasys browsers soon but
will remain unavailable on Firefox, which does not collect height/width stats.
To support VideoStatusLabel showing cross-browser, move the high-definition
detection out of stat sniffing and instead check the video element itself using
an interval in LargeVideoManager. (An interval was used because the temasys
video object does not support the onresize event.) Also, add a cleanup path from
conference.web to LargeVideoManager to remove the interval.

Audio only mode can be used to save bandwidth. In this mode local video is muted
and last N is set to 0, thus disabling all remote video.

When this mode is enabled avatars are shown.

Move logic to open device selection outside of SettingsMenu so
it can be called independently by either SettingsMenu or by
the settings button itself if no other settings but devices will
be displayed.

Saúl Ibarra Corretgé reported that Recording shows an error dialog
stating "There was an error connecting to your camera". Hristo Terezov
and Yana Stamcheva traced that the problem originates in
da4425b5c0
and, more specifically, is caused by a different order of execution due
to the move of the invocation of the function Recording.init.

The solution is to bring back the execution location of Recording.init.

Cleanup existing logic for displaying and updating device
selection settings in the settings menu. In its place
is a button to open the device selection modal.

The Device Selection modal consists of:
- DeviceSelection, an overly smart component responsible for
  triggering stream creation and cleanup.
- DeviceSelector for selector elements.
- VideoInputPreview for displaying a video preview.
- AudioInputPreview for displaying a volume meter.
- AudioOutputPreview for a test sound output link.

Store changes include is primarily storing the list of
available devices in redux. Other app state has been left
alone for future refactoring.

We seemed to be using the names "film strip" and "filmstrip" (and,
consequently, their source code-conscious forms such as film-strip,
FilmStrip, etc.) In order to comply with our coding style which requires
a consistent one name for a given abstraction, choose one name and
rename the uses of the other name.

Wikipedia has a definition of a "filmstrip", I couldn't find a "film
strip". I guess our abstraction can be seen as what's described there.
When I google "film strip", I get results about "filmstrip" at the top.
That's why I chose "filmstrip".

Certain uses of "film strip" such as interfaceConfig.filmStripOnly and
in the external API I left untouched in an attempt to preserve
compatibility.

I wasn't sure whether CSS was tangled in compatibility so I made a
choice and renamed there was well.

* Uses new peer connection statuses to check and show different user msgs.

Checks for interrupted state of peer connection and shows appropriate messages. In case of inactive or restoring state a message is show to user that video was stopped on purpose. Removes some unused parameters from the event handlers about peer connection status change.

* Removes isParticipantConnectionActive.

https://github.com/jitsi/jitsi-meet/pull/1397 (React Toolbar) is huge at
the time of this writing. In order to reduce it, I'm extracting changes
not directly related to React-ifying the Toolbar such as added jsdocs
and source code formatting.
