Hidetoshi Shimokawa c4778b5d1c MFp4: Change struct fw_xfer to reduce memory copy in fwmem_*() functions.
And many changes.

* all
	- Major change of struct fw_xfer.
		o {send,recv}.buf is splitted into hdr and payload.
		o Remove unnecessary fields.
		o spd is moved under send and recv.
	- Remove unnecessary 'volatile' keyword.
	- Add definition of rtcode and extcode.

* firewire.c
	- Ignore FWDEVINVAL devices in fw_noderesolve_nodeid().
	- Check the existance of the bind before call STAILQ_REMOVE().
	- Fix bug in the fw_bindadd().
	- Change element of struct fw_bind for simplicity.
	- Check rtcode of response packet.
	- Reduce split transaction timeout to 200 msec.
		(100msec is the default value in the spec.)
	- Set watchdog timer cycle to 10 Hz.
	- Set xfer->tv just before calling fw_get_tlabel().

* fwohci.c
	- Simplifies fwohci_get_plen().

* sbp.c
	- Fix byte order of multibyte scsi_status informations.
	- Split sbp.c and sbp.h.
	- Unit number is not necessary for FIFO¤ address.
	- Reduce LOGIN_DELAY and SCAN_DELAY to 1 sec.
	- Add some constants defineded in SBP-2 spec.

* fwmem.c
	- Introduce fwmem_strategy() and reduce memory copy.
