Define config register 3 values for NCR53C9x/FAS216.

Changed inaccurate comment on the sc_freq member of the driver's softc

structure. The frequency is represented in MHz rather than Hz. [PR/6805]

If we have an NCR53CF9x (indicated by the front-end by setting a flag
...
in the softc's new "features" word), set FSCSI bit in CFG3 if the sync
period is <= 200ns, or clear it otherwise.

Allocate SCSI message buffers in ncr53c9x_attach(), with a provision
...
for front-ends to override the allocation to avoid alignment
handling in their DMA engines. Note that that ncr53c9x_msgout()
can request a 1 byte DMA transfer that would be difficult to break up.

Merge scsipi branch in the mainline. This add support for ATAPI devices
...
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

Implement target selection using DMA.

To allow a period of testing the variable `ncr53c9x_dmaselect' is used to
enable this feature (default is 0, i.e. the old behaviour).

Allow separate control over the "per-target trace" feature

via the NCR53C9X_DEBUG value. Add some padding for m68k.

New ARP system, supports IPv4 over any hardware link.
...
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
