* yuy2_i420: convert from Packed YUV 4:2:2 to Planar YUV 4:2:0
 * yuy2_i422: convert from Packed YUV 4:2:2 to Planar YUV 4:2:2
 * chroma_chain: attempt to chain 2 chroma converters to acheive the conversion (i.e. yuy2 -> rv32 will be done using yuy2 -> i420 -> rv32)

 * adjust.c, extract.c: packed YUV 422 support.
 * filter_picture.h: code shared by some "video filter2" filters.
 * erase.c: validate the picture chroma in the constructor.

 * colorthres.c: validate input chroma.
 * erase.c: fix bluring application limit (prevents out of bounds access).
 * gaussianblur.c: validate input chroma and add planar YUV 4:2:2 support.
 * psychedelic.c: check image_Convert return value (it fails for I422 which would then trigger a segfault due to a NULL pointer being dereferenced).
 * rotate.c: validate input chroma, add planar YUV 4:2:2 support and misc code fixes or simplifications.

playlist/services_discovery.c: Send service discover started and ended events, to keep track of running sd.

* disable any MMX usage in FFmpeg on Darwin 9 (x86). This way, we can use the ffmpeg module normally until Apple releases the updated ld.

control/media_descriptor.c: Publish an Event plus a method to get the media_descriptor state, which is buffering, playing, error, nothing special. This is a bit controversial as we need a media_instance to set that state, and this is media_instance dependant. However, this is a nice shortcut.

Not every body trusts "free.fr", especially not through non-secure HTTP, and/or non-FQDN-only hostnames

Tell the user about --advanced when his help query skipped advanced configuration items.

Use \033[0;1m instead of \033[37;1m for bold text using the default color (prevent using bold white text on terms with a white background).

Qt4 - Background Widget change. Resetting the maximum size at each resize is wrong. Scaling content can be really really ugly.
To be finished.

Make it possible to inherit the m3u-extvlcopt option in the m3u parser.

macosx: remove useless setting as basically no user wants the wizard panel to reset in a single session, but demands it to keep its selections (this was the default behaviour anyway)

(affects HTTP interface and LUA plus HTTP export for DVB and RTP)

modules/video_output/opengllayer.m: Don't free the gl texture in End(), but in the releaseGLContext function. Set the original bounds of the CALayer. Protect the removeFromSuperlayer by a CATransaction.
