Unparented dialogs are not supported by the window manager. This was
causing a deadlock during VLC startup (There may be other cases left).

QSystremTray class does not exist at all.

Nothing has been using this for a while (how long?). We still have
import for old VLC playlists, though I'm not sure if anybody uses it
either.

Otherwise, checking for forced demux does not make much sense.

Without this when scanning, we would force demuxer to ts but outputted m3u-playlist.

Thanks to nefrir and mfwitten on irc for their help

The fix from quality in [8d8844ad] introduced a weird artefact with dual screens, where the video didn't fill the complete screen. This fixes it.

Currently doesn't yet reset view to default playlist. Atleast worked for me

This piece of code (transparent UTF-16 to UTF-8 conversion) is wrong in
many ways though. This really does NOT belong here, and should be done
in the subsdec plugin instead.

This fixes a regression from [0d1f966a]
