Wim Taymans 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.

Wim Taymans 97567606e2 videoscale: activate Video meta 
Configure the allocator with GstMetaVideo because we can handle that using the
GstVideoFrame helpers.

Wim Taymans 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.

Sebastian Dröge 0c99ab5806 videoscale: Optimize transform_caps() 
If the second and next caps structures are a subset of the already existing
transformed caps we can safely skip them because we would transform them to
the same caps again.

Thiago Santos 91ed9290b8 videoscale: Fix assertion on caps fixation 
When fixating caps, from_par should always be initialized
with a fixed value.

In case the fixation is from src to sink pad it was setting
the from par (srcpad par) to a fraction range, this patch initializes
it to 1/1, based on the assumption that missing PAR is 1/1.

Sebastian Dröge 4d757a29ee videoscale: Only set the PAR if the caps already had a PAR 
Otherwise we're producing different caps and basetransform thinks that it
can't passthrough buffer allocations, etc.

In 0.11 all video caps really should have the PAR set...

Sebastian Dröge 58c77eb1b4 videoscale: Remove interlaced scaling again 
This behaviour was not preferred and caused visible image quality
