We broke external_api.min.js by importing react/features/util which
imported react/features/base/lib-jitsi-meet.
1. To reduce the risks of such a breakage until we add
external_api.min.js to the torture tests, import as little as
possible in modules/API/external/external_api.js.
2. Use the global JitsiMeetJS on Web in react/features/base/util.
* feat(analytics): move to React
The analytics handlers have been moved to JitsiMeetGlobalNS, so now they are
stored in `window.JitsiMeetJS.app.analyticsHandlers`.
The analytics handlers are re-downloaded and re-initialized on every
lib-jitsi-meet initialization, which happens every time the config is changed
(moving between deployments in the mobile app).
* Adds legacy support for old analytics location.
