75bf7638b3 introduced this regression, state must
be assigned as an object, even though one would think it's automagically
initialized to an object. Oh well!

feat: add more accessibility labels

AtlasKit is not fully compatible with React 16. One problem
is PropTypes will not be defined on the React object. So,
add the prop-types shim to the popup bundle.

Adds more accessibility labels required for mobile automated testing.

These modification are not necessarily directly related to the
containing PR, I merely saw them while reviewing the containing PR.

Do the selection in mapStateToProps so the container itself doesn't need to
receive all the props that each overlay needs.

Each overlay is responsible for fetching their own props and for providing a
"needsDisplay" static method wich will be called with the full redux state and
should return true if the overlay needs displaying.

Also eliminate duplicated state keeping: the connection and conference error
states can be fetched from their respective base features.

* On adding participant show the initial status text if any.

When participant joins and there is an initial status we show it, instead of the connected notification. If initial status is missing proceed with the default user connected notification.

* Updates to latest lib-jitsi-meet (365bd886ee).

* Adds a fixme comment.

* Updates to latest lib-jitsi-meet (365bd886ee).

* feat(notifications): prioritize based on type (appearance)

ref(overlay): convert progress bar to react

Updates to latest lib-jitsi-meet (1c743d65ee).

npm: Updates lib-jitsi-meet to dc3397b18b.

Initializing UI features, like keyboard shortcuts, by chaining
onto APP.conference.init is not safe because init can fail,
skipping the initializing of UI features. This can happen when
the room is locked and then a failure event is dispatched into
middleware. I couldn't find a place to properly chain onto
in the APP.conference.init promise chain, primarily due
to the flow continued within middleware, so instead I
leveraged an existing listener for CONFERENCE_JOINED.

* 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).

On DOMINANT_SPEAKER_CHANGED events, switch to the new
dominant speaker regardless of if the speaker has video;
it's okay to show the speaker's avatar.

Always switch to the dominant speaker after unpinning
instead of conditionally checking if the current dominant
speaker has video.

It was decided along with the mute participant dialog reactification
that these types of warning messages should not be toggleable--that
they should simply always display because there is no undo action.
As such, the component NotificationWithToggle is no longer needed.

* fix(notifications): throttle and batch join notifications

Instead of directly calling to show a join notification,
go through a specific method. This method will queue
names for display while a throttled function pulls
the names and shows a notification.

* squash: remove unused translation key

* squash: use default display name

* squash: move into participant actions

It's possible for a track to be disposed but still on the redux store, before
the reducer removed it.

After looking at the jquery-ui documentation, I believe it
is being used only in one place, when toggling the smiley
menu. That toggling has been quickly replaced with a normal
jquery call.

Note: @atlassian/aui also uses jquery-ui but killing that
off will be more difficult due to its CSS being used.

Prepares for the latest eslint & flow-related npm packages which cause
these errors.

While having configuration-specific AppIcons may be of questionable use,
I'm more interested in using the Debug version for enterprise
distribution and the Release version for AppStore distribution.

Overflow on body was set to hidden, likely because of
various tricks used to hide elements off screen in the
SPA. Overflow hidden also has the benefit of hiding
scroll bounce when using a MacBook touchpad. The
welcome page is the exception that needs scrolling,
so style welcome page to scroll.

A couple others had made pull requests to addrses this issue
but there hasn't been follow up.

Click handling was added to the local thumbnail only after
receiving video. Click handling was added to remote thumbnails
only after receiving a stream. To allow for pinning through
the filmstrip in any case, always attach the click handler
on thumbnail init.

Checks exist when clicking a contact list to prevent the pinning
UI from updating if a remote thumbnail has not loaded video.
This was unexpected UX so instead go ahead and pin. This is
accomplished by having contact list clicks to more directly
trigger the flow of a thumbnail being clicked.
