   Move SCB walking code to aic7xxx.c and make it work for all card types.

   The flag AHC_EXTSCB is no longer needed since the SCBs are walked in
   all cases now.

ede8dc43a2 Fixed unsigned longs that should have been vm_offset_t.
vm_offset_t is currently unsigned long but should probably be plain
unsigned for i386's to match the choice of minimal types to represent
for fixed-width types in Lite2.  Anyway, it shouldn't be assumed
to be unsigned long.

I only fixed the type mismatches that were detected when I changed
vm_offset_t to unsigned.  Only pointer type mismatches were detected.

078d5aeeed If FAILSAFE is defined, then:
- Do not enable tagged commands by default
- Probe only 1 LUN
- Do not negotiate sync. transfer with CDROM drives

Defining FAILSAFE will result in a driver that will tolerate
marginal hardware for the price of a slight loss of performance
It is intended for use in install kernels.

218d60ad3d Slight modification of ncr_setmaxtags: set usrtags=0 for drives
that don't announce support for command queues.

SCSI_NCR_DFLT_TAGS can be specified in the kernel config file
and sets the default number of tags per disk drive.
A value of 0 means "no tags".

Minor correction in debug messages: Values from the msg_in
buffer were being printed in the msg_out trace message ...

Remove a backward jump from the NCR script, which allowed a SCSI target
to receive any number of NOP messages it desired. If a target indeed
does such a silly thing, make it fail at the next instruction, instead
of causing a timeout a few seconds later.

3a5a6263e3 Add support for 16 targets on WIDE SCSI bus.
This seems to work fine on my 53c810, but really should be tested on
a 53c825 with at least one target set to an ID >= 8.
The script is now copied to memory mapped using vm_page_alloc_contig(),
since it has to be physically contigous. This must be changed, if the
driver is converted into a loadable module !
Two of the probe messages are suppressed, unless "bootverbose" is set.

8befc21fbd The NCR script has grown beyond one page (4KB). Since malloc() returns
contiguous memory in virtual space, but doesn't guarantee any particular
physical layout of pages, the script may be not contguous in physical
memory. This made the first write command fail in very rare cases.
This has been fixed by checking the region returned by malloc() for
being contiguous, but there should be a physical memory allocate
and later mapping to virtual memory instead.

A few assertions and error messages are improved.

07b1c6b3c9 Remove hard coded assumption that SCSI busses have 7 targets.
This change forces the controller drivers to allocate a scsibus_data struct
via a call to scsi_alloc_bus(), fill in the adapter_link field, and optionally
modify any other fields of the struct.  Scsi_alloc_bus() initializes all fields
to the default, so the changes in most drivers are very minimal.  For drivers
that support Wide controllers, the maxtarg field will have to be updated to
allow probing of all targets (for an example, look at the aic7xxx driver).

Scsi_attachdevs() now takes a scsibus_data* as its argument instead of an
sc_link*.  This allows us to expand the role of the scsibus_data struct for
other bus level configuration setings (max number of transactions, current
transaction opennings, etc for better tagged queuing support).
