* Removes Edge support.

* Removes unused dependency.

It should be provided by the environment, just like on web. This avoids bundling
callstats on web, where it won't be used (we dynamically download it).

This reduces the bundle size from about 1MB to 675KB, almost 40%.

js-utils has some, so we need the preset or webpack fails with a syntax error.

* feat: Read the server region from Jingle and broadcast it with statistics.

* feat: Adds the bridge count to local "statistics", refactors conference-properties.

* fix: Emits the conference properties with the event, small fixes.

* ref: Orders the imports alphabetically.

As described by @virtuacoplenny:
[T]he ordering is based on import path, not import name, with different
file depths being grouped together, node modules being grouped together
at the top.

* fix: Keeps JitsiConference#properties always defined.

* fix: Does not fire an event when the argument is undefined.

Could not update karma-webpack to latest as it was not running because of an error:
The "path" argument must be of type string. Received type object
https://github.com/webpack-contrib/karma-webpack/issues/350

* refactor packet2JSON to not use jquery

also added unit tests for it and switched to use chrome-headless instead
of phantomjs

* update package-lock

* squash: undo sha512 to sha1 conversion in package-lock

Solves a GitHub warning about a vulnerability in a
uglifyjs-webpack-plugin dependency.

* Adds new parameter details for the connection failed event.

Adds suspend and shard_changed details.

* Updates the used strophejs version in dependencies.

* Updates the used strophejs version in dependencies (package-lock file).

* Changes to always report suspend time, reports 0 on no suspend detected.

* Updates the used strophejs version in dependencies (1.2.14-1).

* Changes details field name.

In order to include browser capabilities in RTCBrowserType I needed to
refactor RTCBrowserType.

* Passes getWiFiStatsMethod to callstats.

* Prints WiFi addresses on attachWifiStatsHandler.

* Updates callstats version to 3.27.0.

Required for jitsi-meet upgrade

- Add a new browser check so adapter shim usage can be gated.
- Get track resolution for stats from the track itself to account
  for browser resolution fallback logic. Do this only if
  we can be sure adapter has shimmed it in.
- Create a new getUserMediaFlow, with RTC being the orchestration
  for various RTCUtils calls.
- Remove connection quality stat "resolution" which was being
  emitted but not used but listeners.

* use the centralized jitsi eslint config

* remove redundant extends

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.

It's no longer needed, and it hasn't been for a while.
