* fix(edge): get p2p working up to ice failure

Edge does not support trickle ice. In an attempt to work around
such, and get p2p working, some other work was needed to even
get to the point of ice failure. This is that some other work.

* squash: fix typos, no intermediary map

* squash: remove extra line break

After running `npm install` I end up with a minified library for lib-jitsi-meet. I had to adjust the name to get the example to run

3478 is default for TURN, but not for TURNS. Reported by @damencho.

Implements the promised based getStats. Enables them for Safari and FF.

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

Adds stats and audio levels for Safari. Enables the new getStats API for Firefox, that will get rid of the following warning:
'non-maplike pc.getStats access is deprecated, and will be removed in the near future! See http://w3c.github.io/webrtc-pc/#getstats-example for usage.'

feat: Adds a config.gatherStats parameter.

This PR exposes the functionality that's already built-in the
TraceablePeerConnection that has it gather stats from the wrapped
PeerConnection.

This reverts commit 1c2c63e656.
The logging was initially added to help debug an issue with
connection quality showing lower than expected. The usefulness
of the logging has diminished and is noisy for browsers that
do not automatically filter console.debug, like Edge.

* fix(SS): Set min and max frame rate to 5

Even though I walk through the valley of the shadow of death
I will fear no evil... Reduce indenting and repeated calls to
getting desktop streams by creating a promise chain.

52.

* fix: Adds a missing parameter to a function call.

ref(browser): Use js-utils.

* fix(connection-quality): set min percentage when exceeding a bitrate threshold

In some cases a high bitrate does not equate to a high quality
percentage, because the target itself might be quite high, such
as the case for 1080. In those cases, give credit for the bitrate
being high.

* squash: impl 2, use a max bitrate

* 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.

Add private messages feature

lib-jitsi-meet does not get polyfilled for es6 methods.
Using Array.prototype.find will cause breakages in older
browsers, like ie11. The quick fix for now is changing
the find call to be a for-loop. The long term fix will
be discussed soon.

Fix chromium

This commit will append "-" + tpc.id to every local 'MSID', 'cname',
'label' and 'mslabel', before feeding the local SDP to the Jingle layer.
It will make stream IDs unique across TraceablePeerConnection instances
and prevent from conflicts in some corner cases.

For example this will fix a problem where if the client drops
the conference without leaving the XMPP MUC gracefully and will join
the conference again without recreating the local tracks it would lead
to the MSID conflict, because the stream is still advertised by
"the ghost" participant.

* fix: Fixes version comparison.

* fix(BrowserCapabilities): Searching for the correct version from capabilitiesDB.

* fix(BrowserDetection): Remove unnecessary checks.

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

Avoid throwing an exception if an analytics handler throws one. Emit a warning
though, so the problem can be eventually caught and fixed in the handler.

In Rect Native it will stall the app as it's huge.

jitsi-meet has been changed to have tpc.js on info by default, so these
logs still won't show by default.

fix(ie11): do not call JSON.stringify with temasys ice candidate

Calling JSON.stringify on a temasys object causes a stack overflow.
The result is that the JingleSessionPC's work queue never gets
cleared so future work, like video muting, will not get called.
Instead of passing in the candidate directly, manually do
what chrome's implementation of candidate.toJSON does.

Extract stats about address/port only for selected pairs.
