[Bug 14717] resampled sound is horrible

As for bit depth conversion: the original code provides functions for
converting any sample format (8, 16, 24 or 32 bits) into any. The new code
achieves the same goal by providing the getsample() and putsample() functions
that convert anything to and from double and thus achieve the same goal.

There is one bug, though, in their implementation for 24-bit samples: it
doesn't take the sign bit into account.

Also, it would be nice to avoid filtering the input through the FIR altogether
if no resampling is needed (e.g., 44.1k -> 44.1k).
