ac25b31ede lswr: Improve default resampler's default parameters 
After making some blind tests on a small collection of music
samples for home usage. It turned out that the default cutoff
was too low.

The impact of filter_size was not clearly distinguishable (the
results were on the edge) with the music samples but turned out
to be clearly audible in some synthetic samples.

Thanks to Daniel for helping out with the listening tests.

stdint.h is for the [u]int*_t types, which is the only thing we need for

don't need here.

8ea8833979 swr/resample: move templating parameters to template itself. 
It has various benefits such as allowing some refactoring, clarifying
the code in the inclusion part, and making the template understandable
in standalone.

This commit is based on the templating method used by Justin Ruggles for
libavresample.

04bf2e7f0e swresample: include ff_log2_tab for shared builds 
This is done in accordance with all other libraries, which no longer access ff_log2_tab from avutil directly for shared builds, and instead obtain their own copy.

This change is required for MSVC DLL builds, as well as avoids accessing a private symbol from another library.

1d903a5ee4 lswr: channel_map requires input conversion. 
channel_map is applied between in and postin.
Without this test, if the input format is an acceptable internal format,
the in->postin conversion is skipped. In the best case,
it ignores channel_map, in the worst case it causes an assert failure
if the number of channels is changed by the map.
