* ref(notifications): convert some dialogs to error or warning notifications

- Expand the configurability of the Notification component so warnings
  and errors can be displayed.
- Allow Notification to take in arbitrary text for the body.
- Rename defaultTitleKey to titleKey for consistency with descriptionKey.

* ref(notifications): remove openReportDialog method

openReportDialog is a wrapper around showError that adds
a logger statement. It is being called in one place only
so remove the method and have that one place call logger.

* ref(notifications): UI.showTrackNotWorkingDialog takes a boolean

Change UI.showTrackNotWorkingDialog so it takes a boolean
arguments instead of the entire track. A small refactor so
the method needs to know less.

Instead of targetting a div that contains multiple elements
and risking the elements appearing out of order, create a
specific div for local video to append to.

Removes hasRemoteVideoMenu from RemoteVideo.
In some cases where mod_muc_allowners is enabled we do not see the remote video menu. The problem was in the order of initialization of remote video component.
RemoteVideo#constructor -> Remotevideo#addaddRemoteVideoContainer -> Remotevideo#addRemoteVideoMenu  -> RemoteVideo#hasRemoteVideoMenu = true
Then in VideoLayout#showModeratorIndicator -> !remoteVideo.hasRemoteVideoMenu -> remoteVideo.addRemoteVideoMenu().

By default impromptu uses the first state as the default one to show.

A few occurrences of coding style/formatting which I noticed while
reviewing 'feat(eslint): Enable for non react files'. These are
definitely not all occurrences I could've noticed during the review
but... we're talking about files outside react/ anyway.

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

* 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

ESLint 4.8.0 discovers a lot of error related to formatting. While I
tried to fix as many of them as possible, a portion of them actually go
against our coding style. In such a case, I've disabled the indent rule
which effectively leaves it as it was before ESLint 4.8.0.

Additionally, remove jshint because it's becoming a nuisance with its
lack of understanding of ES2015+.

In Chrome M63 a warning is shown, permissions won't be automatically allowed
afterwards. Reference:
https://sites.google.com/a/chromium.org/dev/Home/chromium-security/deprecating-permissions-in-cross-origin-iframes

Setting this early makes us future proof, while working with current versions
too: Chrome < 63 gives an error because it doesn't understand the option and
Firefox seems to ignore it, so both continue to work as before.

In certain scenarios we do need to import files instead of features but
even then it is our coding style to not write the file extension.

We broke external_api.min.js by importing react/features/util which
imported react/features/base/lib-jitsi-meet.

1. To reduce the risks of such a breakage until we add
   external_api.min.js to the torture tests, import as little as
   possible in modules/API/external/external_api.js.
2. Use the global JitsiMeetJS on Web in react/features/base/util.

- 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.

* feat(analytics): move to React

The analytics handlers have been moved to JitsiMeetGlobalNS, so now they are
stored in `window.JitsiMeetJS.app.analyticsHandlers`.

The analytics handlers are re-downloaded and re-initialized on every
lib-jitsi-meet initialization, which happens every time the config is changed
(moving between deployments in the mobile app).

* Adds legacy support for old analytics location.

* 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

Create a reference to the jquery element instead of querying for
it globally. This is to better encapsulate the small video
component.

This better mimics declarative jsx.

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.

This would better mimic React behavior where each component has
its own markup, instead of relying on markup existing elsewhere.

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).
