0e159f13cf Fixed a few iriver playback quirks and issues with previous fixes. 
Also fixed "TST.." bug when seeking and possible an enhancement to mp3
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.

07c4254135 Don't include the .bss and .ibss sections in the binary image for codecs and plugins. Saves quite some disk space (and buffer space in case of codec changes during playback).

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.

88f4c11789 iPod - Tremor code has become too big for IRAM (as of 28 December 2005), so temporarily disable ICODE_ATTR to fix the broken builds. This needs reviewing anyway when the time comes to optimise Tremor for the iPod.
