Fix "Current fanart" not being shown in DialogVideoInfo.

I'm not sure why and I didn't investigate further, but a combination of early
unpacking the fanart and accessing the CFileItemPtr in place of the CFileItem
fixes the issue.

vda: fix chroma issue with vda upload

GL_YCBCR_422_APPLE need a GL_RGB internal format not GL_RGBA
vda: cvref textures are non power of two so don't allocate extra space
vda: use IOSurfaceGetPixelformat instead of CVPixelBufferGetPixelFormatType

We have converted the texture to an IOSurfaceRef so use that to check
for format.
vda: allocate pot texture if requested
vda: switch cvref rendering over to standard UYVY422 renderer

This gives brightness/contrast/scaling support. The fallback to
old style upload is dropped since GL_YCBCR_422_APPLE
is no longer used.
[ffmpeg/vda] - update for current used ffmpeg (2.2)
vda: allow 3 render buffers
vda: if no image is returned, we must still reset cv_buffer

This is used unconditinolly by ffmpeg, and if not cleared here an
old already released frame may end up being used.
[videoinfoscanner] fix infinite loop

also fixes infinite loop when items[0] is a file
[videoinfoscanner] do not consider optical file paths as valid subpaths
vda: upgrade to hwaccel2 interface
[addons] do show broken/incompatible add-ons that are still installed at this moment so users can un-install them without using the toggle. This makes the  hide broken option only toggle non-installed broken/compatible add-ons.
ffmpeg: if a second GetFormat dis-allow hwaccel, we must restore ffmpeg

This fixes errors in the case that a second instance of a decoder fails, then we must fall back to software again.
gl: multipass renderer would use wrong source pixels sizes

The scaling was inverted for pixel coordinate.
gl: multipass renderer was broken when RECT textures was used as source

FBO is now always rendered with non rect texture target, even if source
is rect.
[skin] update re-touched
Merge pull request #5756 from MartijnKaijser/brokenaddons
