Add assertions and abort in case of invalid |dst_linesize| < bytewidth or
|src_linesize| < bytewidth.

Avoid to silently corrupt memory.

The first parameter is a pointer and NULL is more correct

Move the lavc/imgconvert functions and rename them as follows:
avpicture_get_size -> av_image_get_buffer_size()
avpicture_fill     -> av_image_fill_arrays()
avpicture_layout   -> av_image_copy_to_buffer()

The new functions have an align parameter, which allows to define the
linesize alignment assumed in the buffer (which is set or read).

The names of the functions are consistent with the lavu/samples API
(av_samples_get_buffer_size(), av_samples_fill_arrays()).

This allows simd optimized routines to work in steps of 8 pixels
without going over the linesize. (this matters for yuv->rgb24 for example)

Also remove one pointless zero initialization in rangecoder.c.

This makes it possible to dintinguish them from PAL8.

Fixes an invalid write in avpicture_layout().

Found with address sanitizer.

Allow to factorize code between av_image_get_linesize() and
av_image_fill_linesizes(), and add missing checks.

Increase robustness.

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.

Done to keep ABI compatible. Otherwise this is just silly

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.
