In cf70ba37ba74089a18295b29e77dead0a3222c9e the condition was
changed to use it only for rotation != 0
which broke the cases for which it was intended to be used
as well as breaking cases for which it was not intended to be

Move the lavc/imgconvert functions and rename them as follows:

  avpicture_fill     -> av_image_fill_arrays()

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()).

A redundant check has been dropped from av_image_fill_arrays().

mov: Check angle rather than full matrix when updating SAR

When the display matrix is not the identity one, but the rotation angle

Otherwise, it is possible to obtain negative values which interferes
