video: respect stride alignment when calculating planes offsets

This patch for gst-plugins-base makes all plane start offsets aligned on the
plane stride align value.

The patch by itself is right, however it makes some videos crash when decoding
them with libav. This is because libav needs even more padding at the very end
of each plane, in some SIMD optimized functions. See
https://trac.ffmpeg.org/ticket/2645 and
http://git.videolan.org/?p=ffmpeg.git;a=commit;h=175e916fa20b7887bdb29809817985e481ae0888.
This is a patch from ffmpeg 2.0, even in the latest libav there is an
out-of-bounds write in some cases because the padding is not big enough.

I'm not sure how to add this small padding at the end of each plane with the
current API in gstreamer.
