Make it a subcase of the general algorithm used for the non-bitstream
case. Simplify, and make av_image_get_linesize() and
av_image_fill_linesizes() correctly return the right value when plane
!= 0.
In particular fix a crash occurring with:
-vf format=monow,showinfo,format=monow.
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

av_image_copy(), more consistent with the rest of the API and more
semantically correct.

grepping and somewhat more consistent with the scheme adopted by other
FFmpeg modules API.

The plural form is preferred as it is more consistent with the other functions:
av_fill_image_linesizes()
av_fill_image_pointers()
and looks semantically more correct as it fills an array of elements.

ff_get_plane_bytewidth().
The new implementation is more generic, more compact and more correct.

the pixdescs.
The new implementation is more compact, and does not need to be
updated at each pixel format addition.
Originally committed as revision 24590 to svn://svn.ffmpeg.org/ffmpeg/trunk
max_plane_step_comp by removing the "plane_" word, and add a comment
for explaining what they represent.
Increase readability.
Originally committed as revision 24588 to svn://svn.ffmpeg.org/ffmpeg/trunk
libavcodec/imgconvert.c and make them public in libavcore/imgutils.h,
with the names av_fill_image_linesizes() and av_fill_image_pointers().
