c9ff32215b 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 08d0969c1402ccec4dce44bd430128fb59d7b790.

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.
