This is a follow-up to dae71aacSigned-off-by: Felix Paul Kühne <fkuehne@videolan.org>

I think this should be optimised to rotate symbolrates only
when we get signal but were unable to tune channels.

This commit also causes that eta shows even more strange
times until it gets lock on some channel with correct
modulation/symbolrate.

This enables to keep eg. channel names from dvb playlist when
copying them to medialibrary or inside playlist tree.

Basicly code loops over all modulation before moving to
next frequency position untill we find some channels.

Side effect is that estimate-timer shows funky values.

gzip was including a timestamp, and tar was enumerating files in an
unspecified/variable order.

There have been reports about this. Untested

Also add support for the Private Use Area characters and check for
valid ISO 8859 character sets.

Most progressbars are modal tasks.
Interruptible progress dialogs should be modal then.

Frontend features are in an enum, so ifdef does not work.
