MacOSX/Framework/VLCVideoCommon.m: Previous commit is crashy. Remove it, until we find a proper solution.

MacOSX/Framework/VLCVideoCommon.m: Make sure there is no tearing when moving the splitview in the video window.

Marq: make it possible to mix (x,y) and position options. Example: "marq{marquee=Test,position=1,x=100}" will put the text 100 pixels from the center of the left border. Also add deprecated elements for the old time module options.

control/media_instance.c: Make sure media_instance_pause() will either, play, pause, or stop, depending on the whether the input can be paused or is playing.

control/media_instance.c: Make sure the toggling the of the pause status implies a right "state" callback.

MacOSX/Framework/Sources/VLCVideoCommon.m: Minor typo in previous commit.

Only rewrite the URI if it's a permanent redirection. Thanks to Sebastian Wiedenroth for the patch + some modification by me. Fix #1408

Add YUV420 (I420) and RGB44 (RV32?) chromas to the list, change YVU420 mapping to YV12, change some of the chroma probing code and add information in some of the debug messages.

* Code simplification. Green flashes removal. Call display instead of setNeedsDisplay: to make sure we have a frame per fram
e accuracy. Use removeVoutLayer: to detach the drawer from its drawable.
MacOSX/Framework:
* Code factorization from VLCVideoView, VLCVideoLayer in VLCVideoCommon
* Implement removeVoutLayer: as needed by the opengllayer.
