The minimum resolution needed to show the HD label should be
720, not 1080. However, the requested video quality for
high quality should be 1080.

* 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().

* [iOS] use display: 'none' to hide elements

No, it still doesn't work properly on some Android devices, sigh.

Update to react 16 react-native 49

The root view was not adjusting it's bounds after device rotation.

The intention of the code is (1) to return target if none of the setters lead
to an actual change, (2) to not modify target, and (3) to do it with a 1
copyOnWrite at most.

The intention was to override 'this' argument of 'Error.toString'.

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 popovers in filmstrip only are displaying thinly.
As a quick workaround, set a width on them. There
should only be one anyway, which shows up when
talking while muted.

Firefox flex behaves differently from chrome. In firefox, flex
is not allowing the local video and invite button to exceed
the height of the parent, causing the local video to display
shorter than expected due to the invite button. Flex doesn't
need to be applied for local video in horizontal filmstrip
mode as it's only needed in vertical filmstrip mode to
flip the position of the invite button from above the local
video to below. Honestly, this could be better off done
declaratively in the html, but that's not as straigtforward
in this jquery+react world.

The bottom alignment of the local video container is adjusted
in horizontal filmstrip mode so that the videos remain evenly
aligned at the top but the invite button sticks out. With
the invite button hidden in filmstrip only, this only caused
misalignment. Re-adjust the local video container back down
and put transitions on the filmstrip wrapper itself, instead
of on the thumbnail wrapper level to avoid transitions
when re-adjusting.

All toolbar buttons (which have the class .button) got wrapped
in additional elements due to atlaskit tooltips. This changed
parent/child relationships within the html hierarchy, and the
filmstrip only toolbar selectors needed updating.

It seems to me that npm 5 starting adding github: as the protocol of
dependencies in package.json which are from GitHub. I personally don't
know which npm version supports these and whether we care about such a
support. Anyway, having some use github: and most not is not consistent.

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

This reverts commit 7e831117b6.

This was broken with commit c1fb1a7def, which splits the result in order to print the error reason and in case of error was not returning the error and the message to prosody internals.

Android Studio won't build the app otherwise. Since the gradle plugin 3.0 beta7,
the minimum supported build tools version is 26.0.2, so set it to that. Also
bump compileSdkVersion to 26 since they need to match (in the major number, that
is).

The target API is still 25. Android Oreo (26) brought some changes in overlay
permissions which I haven't figured out yet.

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.

ref(strophe): Remove and cleanup all strophe related code.

Everything strophe related is now handled in lib-jitsi-meet project.

e09949be9f introduced the dark theme globally, but
it only applies to web, so move the logic to App.web.js

Fixes few changes around changing devices

fix(config): Auto hide connection indicators by default

feat(dark-theme): Applies dark theme on inline-dialogs, tooltips, flags and more

Fix device selection popup
