Fixes exception when trying to unmute in the scenario, where someone else is sharing a video with you.

openAddPeopleDialog() got removed so instead call openDialog
with the AddPeopleDialog.

* WiP(invite-ui): Initial move of invite UI to invite button

* Adjusts styling to fit both horizontal and vertical filmstrip

* Removes comment and functions not needed

* [squash] Addressing various review comments

* [squash] Move invite options to a separate config

* [squash] Adjust invite button styles until we fix the whole UI theme

* [squash] Fix the remote videos scroll

* [squash]:Do not show popup menu when 1 option is available

* [squash]: Disable the invite button in filmstrip mode

* feat(connection-indicator): implement automatic hiding on good connection (#2009)

* ref(connection-stats): use PropTypes package

* feat(connection-stats): display a summary of the connection quality

* feat(connection-indicator): show empty bars for interrupted connection

* feat(connection-indicator): change background color based on status

* feat(connection-indicator): implement automatic hiding on good connection

* fix(connection-indicator): explicitly set font size

Currently non-react code will set an icon size on ConnectionIndicator.
This doesn't work on initial call join in vertical filmstrip after
some changes to support hiding the indicator. The chosen fix is
passing in the icon size to mirror what would happe with full
filmstrip reactification.

* ref(connection-stats): rename statuses

* feat(connection-indicator): make hiding behavior configurable

The original implementation made the auto hiding of the indicator
configured in interfaceConfig.

* fix(connection-indicator): readd class expected by torture tests

* fix(connection-indicator): change connection quality display styling

Bold the connection summary in the stats popover so it stands out.
Change the summaries so there are only three--strong, nonoptimal,
poor.

* fix(connection-indicator): gray background on lost connection

* feat(icons): add new gsm bars icon

* feat(connection-indicator): use new 3-bar icon

* ref(icons): remove icon-connection and icon-connection-lost

Both have been replaced by icon-gsm-bars so they are not
being referenced anymore. Mobile looks to have connect-lost
as a separate icon in font-icons/jitsi.json.

* fix(defaultToolbarButtons): Fixes unresolved InfoDialogButton component problem

* [squash]: Makes invite button fit the container

* [squash]:Addressing invite truncate, remote menu position and comment

* [squash]:Fix z-index in horizontal mode, z-index in lonely call

* [squash]: Fix filmstripOnly property, remove important from css

ESLint 4.8.0 discovers a lot of error related to formatting. While I
tried to fix as many of them as possible, a portion of them actually go
against our coding style. In such a case, I've disabled the indent rule
which effectively leaves it as it was before ESLint 4.8.0.

Additionally, remove jshint because it's becoming a nuisance with its
lack of understanding of ES2015+.

* Javadoc introduced @code as a replacement of <code> and <tt> which is
  better aligned with other javadoc tags such as @link. Use it in the
  Java source code. If we switch to Kotlin, then we'll definitely use
  Markdown.

* There are more uses of @code in the JavaScript source code than <tt>
  so use @code for the sake of consistency. Eventually, I'd rather we
  switch to Markdown because it's easier on my eyes.

* Xcode is plain confused by @code and @link. The Internet says that
  Xcode supports the backquote character to denote the beginning and end
  of a string of characters which should be formatted for display as
  code but it doesn't work for me. <tt> is not rendered at all. So use
  the backquote which is rendered itself. Hopefully, if we switch to
  Markdown, then it'll be common between JavaScript and Objective-C
  source code.

This is more of a principle change than a necessary one.
In lib-jitsi-meet, when a getStats call finishes, the
stats are processed and first emitted (and received by
jitsi-meet) and then processed again for sending to
remote participants. Modifying the stats in place changes
the structure of stats before the second processing,
which maybe be unexpected.

* ref(info): be able to open dialog through store

* feat(info): automatically show the info dialog

Conditions:
- Lonely call
- Has not opened the info dialog yet

* squash: change to show on start, hide later

* squash: update naming and comment

* ref(contact-list): remove invite functionality

Removing becuase there is already a toolbar button dedicated
to opening the invite dialog. Now the contact list focuses
on showing current participants.

* squash: remove unused strings and styling

* squash: add plural to panel title

This commit adds initial support for CallKit on supported platforms: iOS >= 10.

Since the call flow in Jitsi Meet is basically making outgoing calls, only
outgoing call support is currently handled via CallKit.

Features:
 - "Green bar" when in a call.
 - Native CallKit view when tapping on the call label on the lock screen.
 - Support for audio muting from the native CallKit view.
 - Support for recent calls (audio-only calls logged as Audio calls, others show
   as Video calls).
 - Call display name is room name.
 - Graceful downgrade on systems without CallKit support.

Limitations:
 - Native CallKit view cannot be shown for audio-only calls (this is a CallKit
   limitaion).
 - The video button in the CallKit view will start a new video call to the same
   room, and terminate the previous one.
 - No support for call hold.

Prepare for React 16.

The implementation of ToolbarButtonWithDialog expects a
constructor function for now, not the object returned
from calling a constructor function.

Gradually, we exploded the error of CONNECTION_FAILED in multiple
redux state properties. The explosion makes maintenance harder because
the properties have to be updated in sync. Collect them in an object
resembling an Error instance.

Do not show the 'Password is incorrect' message when the LoginDialog
opens for the first time.

It is required to clear the flag, before the connection attempt.
Otherwise the app may confuse deployments without guest access with
a one with guess access if it was visited previously and
the WaitForOwnerDialog was canceled. That's because there will be no
conference related event that clears the flag.

* Implement disabling buttons (like Web had the ability).
* Use consistent colors (e.g. for the buttons) like the rest of the app
  (e.g. WelcomePage).
* Enable AbstractDialog to await a thenable from onSubmit and Dialog to
  render a LoadingIndicator in place of the OK/submit button text.

* feat(AddPeopleDialog): invite rooms

Distinguish between 'user' and 'videosipgw' search result items and
invite them with using different method.

* squash: fix typo in AddPeopleDialog.web.js

It will replace the "Join" text button while appNavigate lasts.

Note about the implementation: when appNavigate completes the component
may have been unmounted and thus we cannot touch its state. In order to
avoid this problem I added a 'mounted' instance variable which gets set
and reset in componentWillMount / Unmount respectively. This is to avoid
using isMounted, which is highly discouraged.

The basic indicator is extracted into a LoadingIndicator component,
which then NetworkActivityIndicator displays (or not) based on network
activity.
