Make sure participants in the redux store have updated names.
This will be needed for showing avatars with user initials.

* ref(analytics): centralize all event names

* squash: fix typo and alpha ordering

* squash: rename file to AnalyticsEvents to parallel lib-jitsi-meet

The goal is to reduce usage on atlassian/aui. New components
have been created to display the settings panel. Language
selection will reach into i18n for state whereas moderator
options will keep state in redux.

Properly handle errors while connecting or joining a conference. Prior to this
patch, only errors on established conferences / connections were saved to the
redux store.

* Adds initial documentation for sipgw jibri.

Also explains enabling the people search service and the request/response that are made around sipgw jibri service.

* Fixes add people dialog to invite users and rooms.

No invitation is sent when there is nobody to invite.

* Reuse some recording strings, by using arguments.

* Make sure web also dispatches CONFERENCE_WILL_JOIN.

* Introduces new feature videosipgw.

* Fixes lint errors.

* Renames methods to use people, chatRooms and videoRooms.

* Updates to latest lib-jitsi-meet (dc3397b18b).

While reviewing "[PREVIEW|RN]: Handle getUserMedia in progress" I
discovered JSDoc comments which could be improved. They are not
necessarily 100% related to the PR.

This commit adds extra actions/Redux state to be able to deal with
the GUM operation being in progress. There will be early local track
stub in the Redux state for any a local track for which GUM has been
called, but not completed yet.

Local track is considered valid only after TRACK_ADDED event when it
will have JitsiLocalTrack instance set.

The lib will accept new style constraints and use those
to capture audio/video. By defining the constraints in
config, there is greater flexibility for defining
and changing constraints.

The preceding commit "fix(auth.native): trigger conference left on
cancel" did not correctly clean the redux state up on CONFERENCE_LEFT.

Triggering the 'conference left' action when the wait for owner dialog
is dismissed will let the Call Kit implementation end the call, after
a recoverable conference failed event was emitted.

Also fixes conference state reduction when 'conference left' is emitted
by room lock or auth features where the conference has not been joined
yet.

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

* 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 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+.

It is required to clear the flag, before the connection attempt.
Otherwise the app may confuse deployments without guest access with
a one with guess access if it was visited previously and
the WaitForOwnerDialog was canceled. That's because there will be no
conference related event that clears the flag.

This is only desired when the unmuting action took place due to a manual user
intervention or the audio-only mode being disengaged.

Instead have VideoLayout reach into redux.

- Re-use the native redux pinning implementation for web
- Remove pinning logic from conference.js
- To the native pinning add a check for sharedVideo so
  youtube videos do not send a pin event
- Add shared videos as a participant to enable pinning and
  so they can eventually get added to the filmstrip
- Emit UIEvents.PINNED_ENDPOINT from middleware

* feat(quality-slider): initial implementation

- Add new menu button with an Inline Dialog slider for
  selecting received video quality.
- Place P2P status in redux store for the Inline Dialog
  to display a warning about not respecting video quality
  selection.
- Respond to data channel open events by setting receive
  video quality. This is for lonely call cases where a
  setting is set before the data channel is open.
- Remove dropdown menu from video status label and clean
  up related js and css.

* first pass at addressing feedback

- Move VideoStatusLabel to video-quality directory.
- Rename VideoStatusLabel to VideoQualityLabel.
- Open VideoQualitydialog from VideoQualityLabel.
- New CSS for making VideoQualityLabel display properly.
- Do not render VideoQualityLabel in filmstrip only instead of hiding with css.
- Remove tooltip from VideoQualityLabel.
- Show LD, SD, HD labels in VideoQualityLabel.
- Remove action SET_LARGE_VIDEO_HD_STATUS from conference.
- Create new action UPDATE_KNOWN_LARGE_VIDEO_RESOLUTION in large-video.
- Move VideoQualityButton into video-quality directory.
- General renaming (medium -> standard, menu -> dialog).
- Render P2P message between title and slider.
- Add padding to slider for displacement caused by P2P message's new placement.
- Fix display issue with VideoQualityButton displaying out of line in the
  primary toolbar.

* second pass at addressing feedback

- Fix p2p inline message color
- Force labels to break on words
- Resolve rebase issues, including only dispatching quality
  update on change. Before there was double calling of dispatch
  produced by an IE11 workaround. This breaks now when setting
  audio only mode to true twice.
- Rename some instances of quality to definition

* rename to data channel opened

* do not show p2p in audio only

* stop toggle audio only icon automatically

* remove fixme about toolbar button

* find closest resolution for label

* toggle dialog on button click

* redo last commit for both button and label

* ref(base/conference): add tracks before join

Sometimes it will be suboptimal to add local tracks to the conference,
after the room has been joined. It may slow down the session initiation
process by having to send unnecessary 'source-add' notifications.

* squash: fix typos/comments

Simplify the code by using a bitfied instead of a couple of boolean flags. This
allows us to mute the video from multiple places and only make the unmute
effective once they have all unmuted.

Alas, this cannot be applied to the web without a massive refactor, because it
uses the track muted state as the source of truth instead of the media state.

When the 'startAudioOnly' config option is set to true the conference
will start in the audio only mode.

Keep track of the connection and conference objects so we can leave and / or
disconnect early, before the connection is established or the conference joined.

On mobile we got the extra step of overriding the option and always set it to
true.

Add a menu that displays when hovering over VideoStatusLabel. The menu's
display is controlled by CSS. As the existing AudioOnlyLabel no longer needs
needs its own tooltip, it has been removed and label display logic has been
moved into VideoStatusLabel.
