Instead of continuing with HD/SD/LD, show the eye icon
for when the participant on large video is muted or has
no video.

TouchableWithoutFeedback and TouchableHighlight interfere with the
implementation of 'pinch to zoom' to come. We prepare for it by driving
the onClick/onPress handler(s) out of Conference, through LargeVideo and
ParticipantView into Video itself where the bulk of 'pinch to zoom' will
be implemented.

In preparation for "pinch to zoom" support in desktop streams on mobile, make
certain Views not intervene in touch event handling. While the modification is
necessary for "pinch to zoom" which is coming later, it really makes sense for
the modified Views to not be involved in touching because they're used to aid
layout and/or animations and are to behave to the user as if they're not there.

* fix(welcome-page): modify styling for narrow screens

* squash: fix autoscrolling on mobile safari

This PR takes The Bulldozer Approach (R): removes the old toolbox and lots of
associated code, though not all of it. Subsequent cleanups will follow.

Adds Nat64InfoModule which resolves IPv6 addresses for IPv4 addresses
in IPv6 only network where jitsi-meet deployment does not provide any
IPv6 addresses as ICE candidates.

* fix(info): bold info labels

* fix(info): do not truncate url

* feat(info): show only during a lonely call

* Align hint box text to center

* Fix disappearing hint box on android

Being kicked out of the conference will result with a conference failed
event with 'conference.kicked' reason and take the user back to
the welcome page by navigating to 'undefined'.

* ref(toolbar): add accessibility labels for torture tests

* squash: update propTypes

I don't understand the old showDesktopSharingButton action
but I've tried my best to copy it over. There is an existing
issue where the keyboard shortcut gets registered when it
probably shouldn't because screensharing is disabled. It will
be fixed soon with refactoring of the entire logic determining
whether or not to show the screensharing button.

This is instead of showing the button with a tooltip about it
being disabled.

The onPresence parsing was refactored to remove use of jQuery.
This exposed three methods not available in react-native:
ParentNode.children, ChildNode.remove, and
document.querySelectorAll. The querySelectorAll change could
be swapped for the already polyfilled querySelector, but
children and remove had to be added. The polyfills are based
on those supplied by MDN web docs, but modified to pass jitsi
linting.

The redux flows for video muting may not cover all cases
that the conference.js flows cover. Just exercise the old
flows to be safe.

The redux flows do not account for as many scenarios, such
as config.startWithAudioMuted being true.

* fix(invite): do not send empty queries for people search

The endpoint might return an error if an empty query is sent.

* fix(invite): add error logging for failed people directory requests

The error currently being passed through from $.getJSON ended up
being an empty string plus was not getting logged. So switch to
fetch to move along with jquery killing and log the error.

* fix(dial-in): add error logging for failed requests

* ref(invite): create a fetch helper to remove duplicate logic

* feat(invite): add basic analytics for AddPeople dialog

Analytics for opening the dialog, closing the dialog, the
count of invites sent, and the count of invites errored.

* squash: fix typo, change default count init, remove extra analytics param

Do not take legacy property into account if there's non-legacy value.

* feat(recording): use google api to get stream key

* squash: renaming pass

* squash: return full load promise

* sqush: use google api state enum

* squash: workaround for lib not loading

* another new design...

* increase timeout workaround for gapi load issue

* styling pass

* tweak copy

* squash: auto select first broadcast

Moves the things around to be able to override the config with the URL
params specified in the hash part of the location URI to which the app
is navigating to.

Do not include the protocol part in the intent URL.
