Add the same type of safeguards we use in the mesg_in phase to the mesg_out
phase.
aic7xxx_reg.h:
Add definitions for the DSCommand register for PCI adapters.
aic7770.c:
Simplify the initialization of adapters by pulling all card specific
initialization to the card specific modules.
eisaconf.c:
outb 0x80 instead of 0xc80. The top byte is truncated anyway, and 0x80
was what was intended.
1) Use cpp to preprocess the sequencer code.
2) Convert all "magic numbers" to #defines shared by the sequencer and
kernel driver via the aic7xxx_reg.h file. (The assembler still needs
to be re-written in lex/yacc to allow ~|& type constructions).
3) Raise ATN on parity errors for "in" phases and send an initiator detected
error or message-in parity error message as appropriate.
4) Turn off the reselection hardware from the time or a (re)connection to
busfree. It seems that some fast targets were able to reconnect before
the sequencer was able to see busfree.
5) The message buffer is considered "in-use" when there is a positive length
count. The ACTIVE_MSG flag was unnecesary.
6) Properly set SCB_NEXT_WAITING to SCB_LIST_HEAD in scbs being added to
the waiting scb list. This is a change in how the list code works to
facilitate some planned work in the reset code.
7) The fields in the SCB have be re-arranged to be quad-word aligned.
8) The inb code has been rewritten to catch phasemisses and be more efficient.
9) Go back to "snooping the bus" to determine if the incomming identify
message will be followed by a simple queue message. Its much faster than
doing a search through the SCBs.
10) Implement better tag range checking for incomming tags.
11) Make sdtr_to_rate more accurate (use 25 instead of 24 in calculations -
must have been asleep that night).
12) Rearrange some routines to reduce code complexity and size.
13) Update comments and formatting.
14) Fixed bugs I've forgotten about??

- the fifo was completely disabled for low speeds. Apart from being
unnecessarily inefficient, this invalidated com->tx_fifo_size.
- `ftl' became a bogus name.
- the 16650 probe breaks the COM_NOFIFO() case and has other bugs
(disabled, not fixed).
Fixed bogus change of the fifo settings for the non-speed of 0. This
bug made the above fifo bug occur even at non-low speeds.
Fixed the modes of the cua devices. It isn't possible to set the uid
and gid correctly since the kernel can't know who uucp.dialer is.
Register the devswitch at device attach time. SYSINIT() is not
the right way to initialize devswitches (if anything :->).
Eventually, the devswitch should be deregistered at device detach
and/or unload time and reregistered at device attach time ... Then
some com->gone tests could be removed.
Cleaned up some other recent changes.
#includes to get prototypes.
pci now uses a different interrupt handler type for interrupts that it
dispatches and the isa interrupt handler type for the interrupts that
it handles.
Reduce default value of pcicb_membase to 0x2000000 (from 0x4000000)
since this seems to be the lower bound used by many systems.

getmajorbyname() which were a better (sigh) temporary interface to
the going-away devswitches.
Note that SYSINIT()s to initialize the devswitches would be fatal
in syscons.c and pcvt_drv.c (and are bogus elsewhere) because they
get called independently of whether the device is attached; thus
devices that share a major clobber each other's devswitch entries
until the last one wins.

WARNING... struct lkm[mumble] has changed
so it might be an idea to recompile any lkm related programs
device must be configured. It's hard to tell whether a reset function
should be noreset or nullreset since reset functions are never called.
Most drivers use nullreset but noreset has the advantage of complaining
if somehow gets called).
Removed old aliases d_rdwr_t and d_ttycv_t for d_read_t/d_write_t and
d_devtotty_t.
Sorted declarations of switch functions into switch order.
Removed duplicated comments and declarations of nonexistent switch
