In the V4L2 single-planar API, when format is semi-planar/planar, drivers expect the planes to be contiguous in memory. So this commit change the way we handle semi-planar/planar format (n_planes > 1) when we use the single-planar API (group->n_mem == 1). To check that planes are contiguous and have expected size, ie: no padding. We test the fact that plane 'i' start address + plane 'i' expected size equals to plane 'i + 1' start address. If not, we return in error. Math are done in bufferpool rather than in allocator because the former is aware of video info. https://bugzilla.gnome.org/show_bug.cgi?id=738013
