lavu/opt: allow to set sample and pixel format with av_opt_set_int()
...
This change requires the user to specify min and max value, and makes
possible to prevent the user to set AV_{SAMPLE,PIX}_FMT_NONE if
forbidden.
Add required ifdeffery in case of mixed libraries, when libavutil is
updated but not the other libraries.
This is a followup of 08d0969c14

lavu/opt: change the way default pixel and sample format value is set
...
Use the i64 field rather than the string value. Using a string to set a
default sample/pixel format is weird, also the new interface is more
consistent with the rest of the API.
This is technically an API break, but hopefully there are no applications
using this feature outside of FFmpeg. In order to save backward
compatibility with mixed libraries in case libavutil is updated but not
the other libraries, some ifdeffery hacks are added.
Note that the version check is only performed when class->version != 0,
since if it is not defined then we assume that no version was defined and
the class is not affected by the change.
We will luckily get rid of the hack at the next major bump.

lavu/samplefmt: return the size of the allocated samples buffer at the next bump
...
Make the functions av_samples_fill_arrays, av_samples_alloc, and
avcodec_fill_audio_frame return a buffer size rather than 0 in case of
success. This will be enabled at the next libavutil major bump, in order
to preserve backward compatibility.
Returning the size allows to simplify the code, avoiding a few function
calls.
