vo_opengl: coalesce intra-plane PBOs
Instead of allocating three PBOs and cycling through them, we allocate
one PBO that's three times as large, and cycle through the subregion
offsets.
This results in arguably simpler code and faster initialization
performance. Especially for 4K textures, initializing PBOs can take
quite some time (e.g. 180ms -> 110ms). For 1080p, it's more like 66ms ->
52ms for me.
The alignment to 4096 is completely unnecessary by spec, but we do it
anyway just for peace of mind.
