This new version comes with an updated JSC runtime, so we no longer need to
depend on the updated version ourselves.

Required for the Spot's TURN changes to work

Bring over two fixes for spot. One is for
identifying the screenshare type when using
a camera for screenshare or when using a proxy
stream. Also bring in a fix to avoid a js error
in chrome ios.

Seems like windows does not have emojis for flags.

* Adds new format of phoneList service and re-design dial in numbers page.

Adds flags and country names (with translations) for the numbers if using the new format.

* Fixes tests and fixes get default number.

* Updates swagger with new format.

* Moves html back yo table.

Fixes displaying on mobile and also the tel: URI generation. The tel: URI is tested on Android and iOS and seems to work (Android was not interpreting 'p', but both seems to like ',').

* Fixes a wrong return statement.

* Small fixes.

Updates LJM to 2e1436e20d which includes
the ICE failed notification logic.

We no longer need it since Rect 16 takes care of passing the context around.
It's also deprecated: https://atlaskit.atlassian.com/packages/core/layer-manager

- bump expose-loader to 0.7.5
- remove unused file-loader

NOTE: The first incarnation of this commmit also removed string-replace-loader,
but alas lib-jitsi-meet lists it as a devDependency so it's not installed and we
are currently running webpack on install. This is arguably wrong, but that's a
discussion for another day.

- Change the existing overrides to move the flags
  so the first flag does not cover the toolbar.
- Add a new override to disable the slide in
  animation, as it will play for each flag once
  it becomes the first flag--instead of playing
  only once when the flag queue has items.

The package now requires using a ModalTransition component
to handle animations. The existing DialogContainer component
has been split into native and web implementations to support
this change.

The avid reader may notice we have switched to using our own fork. That is
indeed the case. The upstream author hasn't maintained the library in months,
and changes to the Android build system are required at this point, hence the
fork.

Bumping React to 16.6.3 is a requirement for this update.

* chore(deps): bump lib-jitsi-meet

Brings in a fix for getDisplayMedia being moved onto
navigator.mediaDevices and a hack fix for SDP
interop between Chrome and Firefox.

* Update package lock file sed/http/https.
