macosx: fixed resizing issue, which was in part fixed by the previous commit by accident (close #6203)

Make sure that if we would resize beyond the screen we set the origin values to ensure that the complete window is visible.

i_physical_channels only uses PHYSMASK bits anyway.

There is no reliable way to determine the channel configuration of a
certain ALSA device. The ALSA operates at too low level for that.
So add a configuration option with default to stereo (as in previous
VLC versions). However, the user will not need to re-enable 5.1 every
time.

This commit also removes all the fancy device choices. The static
choices are overriden dynamically by the UI anyway. So the only use of
the list was in vlc --help.

Do not clobber the output format channels to stereo. This would break
the VLC filtering pipeline.

For each input thread the callback for "intf-event" was registered
at least twice, and never deleted correctly.
Therefore this patch makes sure that we add the callback only once,
and also properly delete the old one when the input changed.

macosx_vout: implemented a cleaner approach to limit the window size according to the screen it is displayed on (close #5875)

Server rejects connection if some field are not set properly

The field was renamed in lavc54 and setting values changed from
enum to bitfield.
We don't need to care about this because VLC doesn't specify values.
