ASC - A device driver for a handy scanner
This is a device driver for GI1904-based hand scanners, e.g. the Trust
Amiscan Grey and possibly others. The driver is based on the "gsc"
driver and, partly, on a Linux driver.
The driver has a working select().

- Get all functions prototyped or at least defined before use.
- Make code compile (Mostly) clean with -Wall set
- Start to reduce the degree to which DES aka libdes is built in.
- get all functions to the same uniform standard of definition:
int
foo(a, b)
int a;
int *b;
{
:
}
- fix numerous bugs exposed by above processes.
Note - this replaces the previous work which used an unpopular function
definition style.
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.

and only get errors for files external to this module:
namely

Do it right this time and also explain this behaviour in the man
page. :)

1) Make the driver "quiet" by sticking most boot messages behind
bootverbose conditionals. This means that you won't see the
sync and wide negotiation, but you will find out if they fail.
2) Add support to the 93cx6 serial eeprom code to read at an abitrary
offset. This is needed so that we can access the second half
of the eeprom on 3940 cards where the second channel's config
is stored.
3) Add flags argument to ahcprobe(). This is used by the pci probe code
to tell the generic driver that an adapter should be treated
as a channel B device as well as notify it of the presence of
external SCB SRAM. These are needed for some motherboard
implementations of the aic7870 and for the 3940 controllers.
4) Print "Channel A"/"Channel B" instead of "Single Channel" for the
two busses of the 3940. I received many reports of confusion
about how the 3940 was probed since most people belived that
only one ahc entry was needed. This will hopefully make it
clearer.
5) Walk the SCBs to determine just how many their are if external SCB
ram is detected.
6) Hard code that external SCB ram is present for the 3940 since it doesn't
use the documented reporting facility for reporting the SRAM. :(
255 commands per channel are supported on the 3940.
7) Read the seeprom starting at addres 32 for the second channel of the
3940 so we get the right info for that channel.
8) Clean up printing of the "Disabling tagged queuing message".
9) Queue timeouts if they occur while we are handling a timeout. The code
was totally unprotected in this scenario.

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.

getpwent.c: same as above for _nextyppass(), and also turn a couple of
sprintf()s into snprintf()s to avoid potential buffer overruns. (The
other day I nearly went mad because of a username in my NIS database
that's actually 9 characters long instead of 8. Stuffing a 9-character
username into an 8-character buffer can do some strange things.)
(This reminds me: I hope somebody's planning to fix the buffer overrun
security hole in syslog(3) before 2.1 ships.)
