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.
