It was incomplete and was creating issues when the audio output provided a
non mono device (close #3272).

Use of function references rather than function names to store button
actions. This allows using all kinds of functions, including non global
ones. Note that the old mechanism using global function names is not
supported anymore. Existing scripts will need to be fixed (-> just
remove the quotes around the function name).

Change vlc.stream() and vlc.memory_stream() error reporting to behave like lua's io.open() or loadfile() functions.

close #3361

GetWindowDC paints in nonclient area (not recommended on msdn)
and not needed for skins. Also, it doesn't take WS_CLIPCHILDREN
into account and forced to add a lengthy hack which can now be removed.

This patch hopefully could also fix a refresh issue found only on
Vista/Win7 (to be tested) (http://forum.videolan.org/viewtopic.php?f=15&t=68891)

...without reference. With a direct connection, the call stack ensures
that the pointer remains valid until the slot returns. This is not the
case for asynchronous ("queued" in Qt4 documentation) signals.

Obviously, this means we have to emit the signals from the Qt4 main loop
thread, *or* alternatively not touch any Qt4 UI stuff fromt he slot.
Hopefully, any such bug would be easier to find this ways.

This reverts commit dcd59284.

This bug is so pervasive within the Qt4 interface that removing this
instance won't make a difference.

...unless proper reference counting si involved,
or the signal is blocking queued (but that is deadlock-prone).
