Seungha Yang 6a4e2f4fc9 video-color: Add util functions for conversion from/to ISO/IEC 23001-8 
... and also as known as ITU-T H.273.

The conversion has been handled per plugin for now. That causes
code duplication a lot also some plugins might not be updated with newly introduced
color{matrix,transfer,primaries} enum value(s).

Instead of handling it per plugin, centralized handling can remove such
code duplication and make plugins be up-to-dated.

Seungha Yang 59007d848a video-color: Add ARIB STD-B67 transfer chracteristic function 
It's known also as Rec. ITU-R BT.2100-1 hybrid log-gamma (HLG) used for
both SDR and HDR rendering.

Seungha Yang f7af199b4c video-color: Add SMPTE ST 2084 support and BT 2100 colorimetry 
SMPTE ST 2084 transfer characteristics (a.k.a ITU-R BT.2100-1 perceptual quantization, PQ)
is used for various HDR standard.
With ST 2084, we can represent BT 2100 (Rec. 2100). BT 2100 defines
various aspect of HDR such as resolution, transfer functions, matrix, primaries
and etc. It uses BT2020 color space (primaries and matrix) with PQ or HLG
transfer functions.

Seungha Yang 9d2f9d16a1 video-color: Define bt2020-10 transfer characteristics for clarity 
bt707, bt2020-10, and bt2020-12 transfer characteristics are functionally
identical but have their own unique values by specification.

Guillaume Desmottes 2e939afd73 video-color: add more color primaries formats 
They correspond to index 10, 11, 12 and 22 from ITU-T H.273,

Tim-Philipp Müller ae429de8f6 video: GST_EXPORT -> GST_VIDEO_API 
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

Sebastian Dröge 9041db4680 Revert "video-color: Allow converting incomplete colorimetry to a string" 
This reverts commit 158eae7e7e.

It already *always* allowed to convert incomplete colorimetry to a
string.

Wim Taymans eacb9ee554 video: add method to get offset and scale for a format 
Add a method to get the offset and scale values to transform the color values of
a format to their normalized [0.0 .. 1.0] range. This is usually required as
the first step of a colorspace conversion.
