'command slots' in which the host can put command and wait for the script to start them - Change siop.c to do full disconnect/reslelect, allowing as much as one command per target/lun to run in parallel. - Fix bug in registers init where a board without BIOS would end at ID 0 (now the driver works on alpha too). - better handling of messages, sending back a MSG_EXT_SDTR in response to an incoming MSG_EXT_SDTR, and MSG_MESSAGE_REJECT for unhandled messages. - fix use of bus_dmamap_sync() and htole32(). - supports shared interrups - change some int8 and int16 to int, for alpha and mips benefits ( suggested by Toru Nishimura)
