b79ddf66d2 video: clean up the custom flags
Clean up the flags, make an enum of them. We can now do this because there are
no subclasses of buffer anymore.

24ea19935f audio/video: add format of the pack functions
Replace the unpack_size with an unpack_format, which is more descriptive of the
kind of data the unpack function will create.

1bb83435fd video: Add an id to the video frame
Rename @view_id to @id.
Add an id to the video metadata. Add a method to get the metadata from a buffer
with the given id.
Make a method to map a frame with a certain id. This only maps the frame with
the given id on the video metadata. The generic frame id can be used when a
buffer carries multiple video frames such as in multiview mode but maybe also
when dealing with interlaced video that stores the fields in separate buffers.

9ad89374a3 video: add colorimetry info
Make enums for the chroma siting for easier use in the videoinfo.
Make enums for the color range, color matrix, transfer function and the
color primaries. Add these values to the video info structure in a Colorimetry
structure. These values define the exact colors and are needed to perform
correct colorspace conversion. Use a couple of predefined colorimetry specs
because in practice only a few combinations are in use.
Add view_id to the video frames to identify the view this frame represents in
multiview video.
Remove old gst_video_parse_caps_framerate, use the videoinfo for this.
Port elements to new colorimetry info.
Remove deprecated colorspace property from videotestsrc.

dae848818d audio: rework audio caps.
Rework the audio caps similar to the video caps. Remove
width/depth/endianness/signed fields and replace with a simple string
format and media type audio/x-raw.
Create a GstAudioInfo and some helper methods to parse caps.
Remove duplicate code from the ringbuffer and replace with audio info.
Use AudioInfo in the base audio filter class.
Port elements to new API.

c39ad574aa video: make GST_VIDEO_FORMATS_ALL define more readable
We don't need all those quotes, strings will be parsed as strings
regardless, and g-i doesn't seem to like all those escaped quotes.

ddce68a5c2 video: More video helper library improvements
Make a new GstVideoFormatinfo structure that contains the specific information
related to a format such as the number of planes, components, subsampling,
pixel stride etc. The result is that we are now able to introduce the concept of
components again in the API.
Use tables to specify the formats and its properties.
Use macros to get information about the video format description.
Move code to set strides, offsets and size into one function.
Remove methods that are not handled with the structures.
Add methods to retrieve pointers and strides to the components in the video.

6d9e76f2de video: remove intermediate Plane structure
Remove the GstVideoPlane structure and move the fields directly into the
GstVideoInfo structure. This makes things a little easier to read and also makes
it more likely that we can pass the stride array to external libraries.

a7ae8d41aa video: rework part 1
Add GstVideoFlags similar to the flags on the metadata. The idea is to replace
the metadata flags with the GstVideoFlags.
Move VideoPlane to video.h, it contains the information for a plane.
Add GstVideoInfo structure that holds the current configuration of a video
format.
Add methods to parse caps into GstVideoInfo.

e0a658a664 gstvideo: Add GST_VIDEO_BUFFER_PROGRESSIVE flag
Maps to GST_BUFFER_FLAG_MEDIA4. The purpose is to explicitly indicate
whether a telecined buffer is progressive or not without having to make
assumptions based on previous buffers.
