6c7a0876fe swresample/swresample: do not reset tsf on swr_alloc_set_opts
so tsf option in aresample will have effect
previously tsf/internal_sample_format had no effect

fate is updated
s32p previously used fltp internally
dblp previously used fltp/dblp internally

53a5cea478 swresample/resample: do not allow odd filter_length
except filter_length == 1

odd filter_length gives worse frequency response,
even when compared with shorter filter_length

also makes build_filter simpler

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.

44a7299139 fate: add simple test for async
This only checks that things havnt changed, the values provide little
help in determining if a change is good or bad.

Improvements welcome!
