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.

Magnify: validate input chroma, fix for non "YUV 4:2:0" planar chromas, use a better looking scaling algorithm.

ccess/ftp.c: Fix ftp pausing. Patch by Andrew Zaikin <andrew.zaikin at gmail.com>. Full comment below:
I can see that if you are watching video over ftp and you are pausing playback for a couple of minutes, VLC is unable to resume playback, because corresponding FTP data connection is closed (getting "connection reset by peer" error). To solve this issue I would propose to seek to the current position when VLC is resuming playback. Seek operation in ftp re-open data connection - that is exactly what we need here.

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.
