Qt4 - Open: management of advanced options in capture cards. Mainly finish the open dialog and close #851.
Remains testing to do, refcount and deletion problems, and management of duplication between normal and advanced options.
Remains everything to put in a QScrollArea.

Qt4 - Using already defined configuration type. This is needed for finer control and differentiation between int and bool for the time being.

	- there's still plenty of compile warning
	- I may have been a bit heavy handed on the de-'static inlin'ing 

Validate input chroma in transform filter, make it work with Packed YUV (tested with YUY2 only but should work with other variants). Other misc changes.

Enable --v4l2-audio-method even if ALSA isn't available (makes it possible to disable the audio input using --v4l2-audio-method 0). Change a few variable types. Print the fourcc when a v4l2 format isn't supported.

v4l2: Fixed audio init & close.  Added some comments to help the readability of the main device detection logic.

If the v4l2 driver supports the extended controls API, use it to list controls (instead of the user control API).

Makefile.am: try it the simple way now, trusting the user not to open another dmg with the same name

live-starttime.patch is merged upstream and bumping up livemedia's version number is no longer needed.

MacOSX/Framework/VLCEventManager.m: Don't send grouped events to the same target if there is an event in-between.

Qt4 - extended... attempt to fix extended panel size... The culprit is still the VideoFilter Widget.

video_output/opengllayer.m: Don't rely on CAOpenGLLayer when frames should be displayed. Display frame when vout tells us to do so.
