Show drift value in debug log

The frame rate is retrieved from the capture parameters nowadays. This
option has no effects at the moment.

It might be nice to reintroduce it so that it can select one rate when
a device supports more than one. But that was never implemented so far.

Close #7240

The "item-change" callback is called with the playlist lock held in
at least one case: when the now playing meta is cleared while a new
input is created by the playlist.

playlist_CurrentInput() acquires the playlist lock. So the
"item-change" callback cannot call it. This bug is present in the
Growl, MSN and Telepathy modules since version 1.0.0. It got copied
into Notify in version 2.0.0.

This reverts commit fc56b92a.
This should fix #6641.

As discussed in May 2012, this plugin has been deadlocking since
VLC 1.0.0. So I gather it is unused and unmaintained. Also, it does not
seem to be using libdbus safely.

As discussed last May, this has been silently broken since VLC 1.0.0.

macosx: CAS: added a label to sum up the current streaming settings in case that the stream sheet is closed

Additionally, remove the Cancel button since it was against the HIGL

macosx: make sure that the marquee is displayed correctly when enabled for the first time in a session

Previously, the OS automatically switched from integrated graphics to dedicated ones as soon as VLC is launched since it is using OpenGL. Of course, that's wrong, since VLC runs quite nicely on the integrated ones to draw its single texture, so there is no need to waste battery life on the dedicated card.

Trust the ObjC runtime, it will do its job properly.
