4977692461 swresample: Choose 16bit internally only if input and output is 16bit or less 
or if no rematrix and no resampling is performed and the input is 16bit
note reampling and rematrix itself always use more than 16bit internally
the "internal" sampling format is the format between these steps

Its unlikely the difference from this commit is audible in any case
unless there is some bug either before or after the change.
but multiple people prefer this and it slightly improves the precission
of computations.

334e2e2363 lavu,lavc,lswr: do not hardcode AV_SAMPLE_FMT_NB value when setting sample format max value 
The constant may change in libavutil but the library may be compiled
against an older version, thus rejecting a value which is otherwise
supported by the new libavutil.

INT_MAX is used here to denote the max allowed value for a sample format.

The opt-test code is changed to provide a valid reference example.
