90b21ae5b5 avfilter/af_astats: fix msvc compile error 
MSVC requires an explicit cast from void * to void when applying the
ternary conditional operator to switch between methods that return
void.

5cc4b79b29 avfilter/af_astats: rework sample loops 
The channel loop is now the outer loop for both planar and interleaved. This is
needed by the next patch, and the speed difference is negligable if any.

e85f37d51e avfilter/af_astats: add support for selecting measured statistics 
set_metadata with many entries is not very efficient, and with small audio
frames the performance loss is noticable. Also with this very simple
calculations (like peak) can be even further optimized.

Unfoturnately there are some small differences in metadata and av_log info
output, so factorizing calculations and output might not worth the hassle.
