Without this I needed to give --dvb-srate=6875000 to vlc with
channels.conf file for it to work proberly, please review that it
doesn't cause any funky issues to other than dvb-c stuff.

The caller is going to call poll() or something, so locking a mutex is
surely not a performance issue.

 It seems that both gui/pda/pda.c and gui/macosx/intf.m fetch "can-rate" value
but does not use it, could maintainers check it ...

 The inhibit and screensaver modules are using bad object_find. Proper
playlist event handling would be cleaner.

The wait STILL frame is handled by dvdnav is not right.

macosx: changed the data appearance in the info panel to the following behaviour: if playlist is collapsed, we show data about the currently playing item. if the playlist is shown, we show data about the current selection in the list, regardless of the current item.

Empty selections in the playlist are still not allowed, as this would lead to some trouble I don't want to solve for this old panel (to be fixed once the dudiak branch is merged)
