-YouTubeVideoUrl: fallback to web client if android client failed with exception
-YouTubeVideoUrl: fix some age gate content
(Old get_video_info endpoint is dead now, so use new age gate bypass implementation with android client.
Not work on all age gate content. Thx MinePlayersPE)
-YouTubeVideoUrl: improve signature function detection (Thx PSlava.)
-YouTubeUi: on error show only video Id in message box
-OAuth: small code optimization
-YouTubeVideoUrl: remove unused url_or_none
-YouTubeVideoUrl: remove fallback to WEB client
(Streams from the WEB client are not normally used.
Therefore, the WEB client is removed, with this deleting a lot of unusable code.)
-YouTubeVideoUrl: fix E225 missing whitespace around operator
-YouTubeVideoUrl: recreate priority list also for live streams
-YouTubeVideoUrl: remove unused parametrs in _extract_player_response
(I intended them for the IOS client to use for Live HLS streams.
Unfortunately, these streams are just video without sound.)
