 OpenGL: Optimize writing packed images to pixel buffer objects (PBO)

 pack_yv12interlaced() packs pixels and writes them to an OpenGL
 pixel buffer object.  This buffer may reside on the graphics card
 so writes may be slower than to RAM.  Combining writes to the buffer
 can improve performance by 200-300%.

 This patch also provides optimized non-mmx code and also tightens
 const correctness.
