These 2 extra conversions (CVPX_X to CVPX_RGBA and CVPX_RGBA to CVPX_X) will be
done only if ci_filters doesn't accept the input chroma. This won't happen
often since videotoolbox will most likely output chromas that can be accepted
by ci_filters.

This was not never touched since the initial commit and was not up to date.

"add_float_with_range( "hue", 0, -180., +180. ..."

Even if 360 is the same than -180 in the hue case, you can't pass value outside
the range anymore (since VLC 3.0).

But match the colorspace of the cvpx buffer.

Symbols availability are checked at entry point.

This will hopefully fix crashes on iOS 8*.

irc-log:
<ePirat> ... it will not make the symbols weak (because they already exist on
the lowest version you specified) and things will just crash/error at runtime.

Fixes #19098, regression from commit 7dd8a23d

Otherwise we use the global LDFLAGS that's set for modules and export the
module resources many times.

Also move the documentation and set the functions static.

This is an Objective C module, therefore it should use OBJCFLAGS instead
of CFLAGS.

For example:
vlc --video-filter ci --ci-filter CICrystallize

When filtering a 1080p YUV2 video, CPU goes from 60% to 40%. Ideally, the vout
should be reconfigured to switch from YUV2 to BGRA to get the best performances
possible.

CoreImage can accept YUV2 as input (it'll do a conversion internally), but it
can't output this same chroma (so the dst_cnverter is still needed).

And require kCGColorSpaceITUR_709.

This reverts commit 9367f189.

Use the [CIContext render:toCVPixelBuffer:] method (since macos 10.11, iphone
5.0) that handle automatically the color space.

kCGColorSpaceITUR_709 was only introduce in 10.11, if this is not
available, error instead of still trying to use it.

No need to convert BGRA to NV12 since this color is handled natively.
