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.

52b7823b73 swr: include stdint.h instead of inttypes.h. 
stdint.h is for the [u]int*_t types, which is the only thing we need for
the prototypes. inttypes.h includes stdint.h and defines more thing we
don't need here.

Bump micro in case a user app was relying on this include for its own
code.

c02ae48271 swr: set default channel count options to 0. 
If not set, they will be defined using the channel layout setting, which
is much more convenient when using swr_alloc() instead of
swr_alloc_set_opts().

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.
