other loops a little bit.

ff40af42ba Streamlined WavPack decoder by utilizing dsp functionality where it was 
applicable (like mono conversion and clipping) and eliminating the
conversion to 16-bit samples (everything is now returned as 28-bit).
This reduced boost ratio (on iRiver) by about 7% on those tracks that
require it.

347992e9d9 Optimised C version of count_leading_zeros() taken from alac-0.1.1. This makes ALAC very close to realtime on the ipod (just the very occasional skip during disk reading - it is realtime when the disk is sleeping).

gapless playback also.

b8749fdf21 New codec loader, using the same mechanism as the new plugin loader. API version numbering restarted for the new system. Uses the target ID from configure, so don't change that too often. * Fixed sim_plugin_load_ram() to truncate the tempfile. * Reduced plugin buffer size to 512KB for iriver and iPod.

0e419987e4 SDL simulator brought by Nathan Hand and Nick Lanham. This is added as a third 
simulator with the hope that once it works fine, we can remove the other two
and only have one unified simulator.

c78b019944 I figured out what was *really* causing the MPC track-change noise, so I 
backed out Thom's change and made the appropriate change. Note that this
should not fix the track change *pop* because there still seems to be a
problem decoding the first and last several hundred samples of MPC files.
