Log Message:
Speedup patch, which achieves a big speedup. When all optimizations can be
used, it should be more than 50%.
 * inline Mpegtoraw::putraw
 * inline Mpegtoraw::get1bit/getbits9
 * use a table, to make huffman decoding a simple table lookup in most cases
 * avoid float -> int -> float conversions for mp3 decoding
 * resample only if necessary (i.e. don't if artsd and the mp3 are 44100 Hz)

It seems like timestamps need a little fix somewhere, as time passes twice
as fast now. ;)
