Rely on generic utilities for computing each plane linesize.
In particular, add support to NV12/21 formats and avoid use of
PIX_FMT_PLANAR pixdesc flag, whose semantics is questionable.
It also fixes various crashes.

If there is a sample_aspect_ratio in the stream, then apply it to every
decoded frame in the same way as avconv does. This also makes sure that
the avfilter chain has access to the aspect ratio.

In some ASF files this objects holds cover art and other tags. Compared to
Metadata Object it can also hold GUIDs, but we ignore these for now.

aligned dsputil (for sh4) patch by (BERO <bero at geocities dot co dot jp>)
Originally committed as revision 1880 to svn://svn.ffmpeg.org/ffmpeg/trunk
commit 8dbe585641
Author: Oskar Arvidsson <oskar@irock.se>
Date: Tue Mar 29 17:48:59 2011 +0200
Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder.
This patch lets e.g. dsputil_init chose dsp functions with respect to
the bit depth to decode. The naming scheme of bit depth dependent
functions is <base name>_<bit depth>[_<prefix>] (i.e. the old
clear_blocks_c is now named clear_blocks_8_c).
Note: Some of the functions for high bit depth is not dependent on the
bit depth, but only on the pixel size. This leaves some room for
optimizing binary size.
Preparatory patch for high bit depth h264 decoding support.
