Modified Files:
	syssrc/sys/dev/ic: siop.c siopreg.h siopvar.h
	syssrc/sys/dev/microcode/siop: siop.out siop.ss

Log Message:
- Change the script to start new commands in an asyncronous way, using
 '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)
