b2608b2c73 Staticize the overrun buffer so that they are not shared between
cards of different bus types as each bus type may have a different
bus mapping.

2127f26023 Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

bb415a7e88 Fix breakage introduced by last patch. bde has added CC_QUIET flag to
hasseen_isadev so this will be less noisy when conflicts do exist.
Also eliminate redundant warnings about conflicts.

19bed41a5d Fix conficts in probe:
o For bt and aha only probe the one I/O range if a specific I/O is specified
  in the config file.
o Don't even try to probe I/O ranges that have been seen already.
o If we conflict with an IRQ or DRQ, then fail the probe.

f8c5944d43 Only pull 16 bits of residual information from completing queues. This
is a work-around from an LRAM access bug on the 940UA.  In a future
microcode revision, the high 16bits of residual information will be moved
to a safe location and we'll return to 32bit residuals.  Since we only
allow 64KB I/O, 16bits is enough.

217a0a47e4 Don't set the active flag on a transaction resource until it has been
queued.

Perform dma segment setup outside of splcam protection as this can take
some time and the protection is not necessary.

Inline a function.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

0a42ab8379 Advanced Systems Inc. SCSI Controller driver and ISA/VL front end.
I have only tested the ABP5140 card and only with a single CDROM drive
but it seems to work fine.  This driver relies on features found only in
the SCSI branch so will not work in -current until those changes
are brought in.  It also doesn't have any error handling code *yet*.
The goal is to use this driver as the development platform for the new
generic SCSI layer error recovery/handling code.

PCI and EISA front ends will show up as soon as I get my hands on
the cards.  There are also a few issues in the driver that I need
to clear up with AdvanSys before I can suggest sticking one of
these cards in your server. 8-)

Thanks to AdvanSys for releasing this code under a suitable copyright.
