This commit moves some of the functionality from avfilter/colorspace
into avutil/csp and exposes it as a public API so it can be used by
libavcodec and/or libavformat. It also converts those structs from
double values to AVRational to make regression testing easier and
more consistent.

Changes in v2:
- increase precision for AVR() macro to 100k, at haasn's request
- add #define AVUTIL_CSP_DENOM 10
- add 0.5 to the AVR macro definition to get exact values from truncation
This patch is a work in progress example for swapping these
structs from doubles to AVRationals.

Changes since the v4:
- Avoid having two mf_init function declared (missing #if !HAVE_UWP)
- Better commit message about linking with UWP
Changes since the v3:
- Library handle and function pointer are no longer in MFContext.
- If UWP is enabled, avcodec will be linked directly against MFPl
This patch add another ARIB caption decoder using libaribcaption
external library: https://github.com/xqq/libaribcaption
Unlike libaribb24, it supports 3 types of subtitle outputs:
* text: plain text
* ass: ASS formatted text
* bitmap: bitmap image
Default subtitle type is ass as same as libaribb
Some additional properties are set for ARIB caption.

ARIB caption doesn't require any parser.
This avoids "parser not found" warning message.

- Library handle and function pointer are no longer in MFContext.
- If UWP is enabled, avcodec will be linked directly against MFPlat.DLL.
- MediaFoundation functions are now called like MFTEnumEx, like Martin

The test /libavutil/tests/hwdevice checks that when deriving a device
from a source device and then deriving back to the type of the source
device, the result is matching the original source device, i.e. the

There has been an objection that the earlier patchset would change API

Not possible for stat precisely because of function and struct sharing a name.
