cdf55c7c7a video-blend: prepare for 0.11 porting 
Remove obsolete code.
Remove the BlendInfo structure, we can do this better with GstVideoFrame
Use GstVideoFrame in the API
Prefix functions with gst_

3242f55861 test: fix leak in video overlay composition unit test 
gst_buffer_set_qdata() will leak the structure passed to it
when called incorrectly (e.g. on a non-metadata-writable buffer).
This is expected, but we must avoid doing that in valgrind.

79953f27a8 video: overlay-composition: try to avoid floating point maths in inner loop 
Try to avoid floating point maths for each pixel to be blended in
inner loop, and try to avoid the multiplication entirely for the
most common case of the global alpha being 1. Could probably be
refactored a bit more.

80054a3b1e video: add some internal helper functions for image blending 
This could be improved if we decide we don't need it to
be this generic/flexible.
