Clément Bœsch 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.

Michael Niedermayer 947215a261 swr: dont use SWR_CH_MAX in the public function declaration.
This change should make no binary difference to the generated code.
the API version is just bumped for correctness sake, this is not
really a API or ABI change.

Michael Niedermayer b5875b9111 Add libswresample.
Similar to libswscale this does resampling and format convertion, just for audio
instead of video.
changing sampling rate, sample formats, channel layouts and sample packing all
in one with a very simple public interface.
