Fixed AHA-154x scatter/gather transfers; Two-phased SCSI read-direction commands; Made scsi_bus.c use a dynamically malloc'd buffer instead of a giant fixed-size buffer; The AHA-154x/BusLogic thread now uses mutexes; The BusLogic BT-545C is now the BT-545S; Added the BusLogic BT-542BH; The AHA-1542CF now again uses the v2.11 BIOS as the CD booting now works; Applied PCem commit that adds NMI support to the recompiler; Applied PCem commit that adds the IBM XT 286; Applied PCem commits that have to do with sound, including the ES1371; Fixed the NCR5380 output data register; Moved the SLiRP mutex stuff from win.c to the appropriate network files; Added sanity checks to everything in win_thread.c.
