eliminates many local symbols that could not be removed by the "ld -r -x"
steps on the individual object files. It makes shared libraries
substantially smaller -- almost 11%, in the case of libc.so.3.0.

SCB paging is enabled with the option "AHC_SCBPAGING_ENABLE". Full
comments on the algorithm are at the top of i386/scsi/aic7xxx.c.
options "AHC_TAGENABLE" and "AHC_QUEUE_FULL" have been removed. The
default is 4 tags without SCB paging, 8 with.
Clear the SCSIRSTI bit after throwing a bus reset. Some cards seem to get
confused otherwise.
Handle SCSIRSTI interrupts before checking to see if there is a valid
SCB in use since this can happen. (Clears PR# i386/1123)
Clean up the way we determine the number of SCBs on the card
(courtesy of Dan Eischen).
Guard against attempts to negotiate wide to a narrow controller.
Fix some comments.

aic7770 >= Rev E, aic7850, aic7860, aic7870, and ai7880 based controllers.
Make findSCB safer for non-tagged commands when tagged commands are
active on the controller. The symptoms of this problem were
"Overlapped commands attempted" messages during error recovery
attempts.
Compact scratch ram usage. This leaves 8 bytes free for future use.
Clean up some comments.

compatibility slice. They were forgotten on last-close and then
creating them on first-open failed.
Devfs entries for slices other than the one containing the root file
system are still invisible unless you open a non-devfs inode on the
slice.
This commit covers the man pages for most of the ANSI library functions.
A few others such as strtol.3 have to mention <sys/types.h> because they
mix ANSI interfaces with less well designed extensions.
- More code cleanups
- #ifdef DEBUG debugging code
- More consistant printfs
- Better handling of the apm_int() assembly code (mostly from Bruce Evans)

1) Require all callers to pass a valid route pointer to ip_output()
so that we don't have to check and allocate one off the stack
as was done before. This eliminates one test and some stack
bloat from the common (UDP and TCP) case.
2) Perform the IP header checksum in-line if it's of the usual length.
This results in about a 5% speed-up in my packet-generation test.
3) Use ip_vhl field rather than ip_v and ip_hl bitfields.
DITEM_FAILURE - formerly they would simply act as an implicit "continue",
but this is wrong. If you want this behavior, you should now return
with the DITEM_CONTINUE flag set.
Also make the semantics of DITEM_RESTORE quite a bit different - rather
than restore the screen back to pre-menu state, we restore the menu
itself. This is more correct for a variety of reasons when dealing with
nested menus (whoops!).
