Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.
Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

Merge the dev_clone and dev_clone_cred event handlers into a single event handler, dev_clone, which accepts a credential argument. Implementors of the event can ignore it if they're not interested, and most do. This avoids having multiple event handler types and fall-back/precedence logic in devfs.
This changes the kernel API for /dev cloning, and may affect third party packages containg cloning kernel modules.

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.

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

Improve if_fwe performance. - Simplify mbuf handling by using bulkxfer.

Improve SBP device probeing: - Wait 2 sec before issuing LOGIN ORB expecting the reconnection hold timer expires. - Serialize management ORB and scanning LUN by CAM on each target. This should fix the problem for devices which have multiple LUNs. Test device is donated by: Jaye Mathisen <mrcpu@internetcds.com> - Freeze SIM queue for 2 sec after BUS RESET. - Retry with LOGIN rather than RECONNECT after LOGIN is not completed for BUS RESET. - Use appropriate CAM status for BUS RESET and DEVICE RESET. - Let CAM to scan targets after BUS REST. - Implement CAM scan target function. - Keep our own devq freeze count. - Let CAM to know that SBP does tagged queuing.
These should be merged to RELENG_4 before 4.8-RELEASE.
