The original code was intended purely for rotation == 0
In cf70ba37 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
used.
This changes the code so it could work for the more general
case and fixes the regressions
If you have sample files that are not handled correctly
please open tickets or mail me!

In v2.2, the picture type is not a zero-terminated string, but has a
constant size of 3 bytes.

Some of them are not immediately obvious.

Those functions should not ever modify it.

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()).

A redundant check has been dropped from av_image_fill_arrays().

When the display matrix is not the identity one, but the rotation angle
is zero, there is no need to update the sample aspect ratio.

Otherwise, it is possible to obtain negative values which interferes
with transcoding in later stages. This kind of behaviour is reproducible
on mov files with "major_brand: MSNV".

Return proper error code, print an error message and add missing
parentheses.

Previously the image sequence was always starting from the minimum
number rather than the requested one.
