video: add more info in the format structure
...
Add a field to describe how many bits are used to pack items.
Specify the shift for each component.
Add some more flags to better describe the format.

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.

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.

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.

happen anyway. Thus have a warning before the final return to make it easier to

This fixes a regression that an assertion would happen if
gst_video_get_component_offset would be called with width or
height as 0.
Calling it with 0 is fine if the format isn't yuv and this
was already being used in some other places of video.c
