* Improve accessibility and testability of Tooltip
Adding a role to Tooltip was motivated by React Testing Library's
reliance on accessibility-related attributes to locate elements.
* Make the ReadyWatchingStore constructor safer
The ReadyWatchingStore constructor previously had a chance to
immediately call onReady, which was dangerous because it was potentially
calling the derived class's onReady at a point when the derived class
hadn't even finished construction yet. In normal usage, I guess this
never was a problem, but it was causing some of the tests I was writing
to crash. This is solved by separating out the onReady call into a start
method.
* Rename 1:1 call components to 'LegacyCall'
to reflect the fact that they're slated for removal, and to not clash
with the new Call code.
* Refactor VideoChannelStore into Call and CallStore
Call is an abstract class that currently only has a Jitsi
implementation, but this will make it easy to later add an Element Call
implementation.
* Remove WidgetReady, ClientReady, and ForceHangupCall hacks
These are no longer used by the new Jitsi call implementation, and can
be removed.
* yarn i18n
* Delete call map entries instead of inserting nulls
* Allow multiple active calls and consolidate call listeners
* Fix a race condition when creating a video room
* Un-hardcode the media device fallback labels
* Apply misc code review fixes
* yarn i18n
* Disconnect from calls more politely on logout
* Fix some strict mode errors
* Fix another updateRoom race condition
This is more general maintenance than performance as the RoomList doesn't need to be generating layouts for the sublists, and it certainly doesn't need to be creating a bunch of extra ones.
The sublists are perfectly capable of getting their own layout instance and using it, and we are perfectly able to limit the number of these things we create through the session's lifespan.
