Copy stable/10@r272459 to releng/10.1 as part of

MFC r258779,r258780,r258787,r258822:

Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.

Similar to the (1 << 31) case it is not defined to do (2 << 30).

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

Recognize the integrated (though not necessarily enabled) FireWire
controllers of Sun PCIO-2 chips which are used onboard in most of
the newer PCI-based sun4u machines (cosmetic change as they were also
already probed as generic FWOHCI without this). As with gem(4), hme(4)
and ohci(4) detect whether their intpin register is valid and correct
it if necessary, i.e. set the respective IVAR to the right value for
allocating the IRQ resource, as some of them come up having it set
to 0 (in fact in all machines I'm currently aware of the FireWire
part being enabled). This fixes attaching affected controllers.

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.

Fill reserved fields of transmitting packets header with zero.
This fixes the if_fwe problem with 1394b chip.

MFp4(simokawa_firewire):
Many internal structure changes for the FireWire driver.

- Compute CRC in CROM parsing.
- Add support for configuration ROM build.
- Simplify dummy buffer handling.
- busdma conversion
- Use swi_taskqueue_giant for -current. Mark the interrupt routine as MPSAFE.
- AR buffer handling.
Don't reallocate AR buffer but just recycle it.
Don't malloc and copy per packet in fwohci_arcv().
Pass packet to fw_rcv() using iovec.
Application must prepare receiving buffer in advance.
- Change fw_bind API so that application should pre-allocate xfer structure.
- Add fw_xfer_unload() for recycling struct fw_xfer.
- Add post_busreset hook
- Remove unused 'sub' and 'act_type' in struct fw_xfer.
- Remove npacket from struct fw_bulkxfer.
- Don't call back handlers in fwochi_arcv() if the packet has
not drained in AT queue
- Make firewire works on big endian platform.
- Use native endian for packet header and remove unnecessary ntohX/htonX.
- Remove FWXFERQ_PACKET mode. We don't use it anymore.
- Remove unnecessary restriction of FWSTMAXCHUNK.
- Don't set root node for phy config packet if the root node is
not cycle master capable but set myself for root node.
We should be the root node after next bus reset.

Spotted by: Yoshihiro Tabira <tabira@scd.mei.co.jp>
- Improve self id handling

Tested on: i386, sparc64 and i386 with forced bounce buffer

Use pci_get_devid().

Add 'uPD72871/2 IEEE1394 1-Chip OHCI Host Controller'.

- Split db.desc.cmd into desc.control and desc.reqcount.
- remove unncessary descriptor updates.

- Remove speed_map API because speed_map is obsoleted by 1394a.
- Add definition of OHCI_HCC_BIBIV in fwohcireg.h.

Fix and add several device IDs.

firewire.c
- Fix permission of device node.

fwochi.c, fwohcireg.h
- Detect phy access failure correct way.
- Set root hold-off bit before initiating bus reset.
This should fix the problem with VIA6306.

fwohcivar.h
- Fix over-allocation of array. (fwohcivar.h)

sbp.c
- Return CAM_DEV_NOT_THERE rather than CAM_TID_INVALID to prevent retry.
