1. Create 2 x 8k transmit buffer blocks in place of the 16k block previously.
With this change the speed as tested with ttcp on a 2Mbit link went up
from 206kbyte/s to 236kbyte/s.
2. Change the rest of the functions to also have the definition of the
return value on a sepperate line.
3. Remove some unused variables.
4. Add code to recover from DMA underruns.
5. Reorder ar_get_packets() to handle errors better.
6. Only allocate a mbuf cluster if the data is more than the mbuf.
(and in a second diff in addition to the above)
7. Stops the occasional DMA underruns that occurred when 2 channels
are running at 2Mbit/s.

loader is also present in the coff loader. It was possible to get one
more page allocated than needed, which would cause brk()/malloc()/etc
to fail with ENOMEM when it tried to re-allocate the space.
Also, change a bcopy() from kernel to user space to a copyout().
just in case a connection already existed.
Also, a minor optimization in the code which determins if a APM BIOS exists.

This is based on the APM-0.5 patch for Linux, but written entirely by me.
To complete this, some extra state has to be kept somewhere so that the
B38400 flag in Linux can be correctly translated to/from either 38400,
57600 or 115200.

this code was not quite right (linux has a readdir and getdents syscall,
with the same args. readdir only returns one entry and uses a mutant
dirent structure. This code was also returning the mutant form for
getdents as well. My fault for missing this before.)
Compile and link a new kernel, that will give native ELF support, and
provide the hooks for other ELF interpreters as well.
To make native ELF binaries use John Polstras elf-kit-1.0.1..
For the time being also use his ld-elf.so.1 and put it in
/usr/libexec.
The Linux emulator has been enhanced to also run ELF binaries, it
is however in its very first incarnation.
Just get some Linux ELF libs (Slackware-3.0) and put them in the
prober place (/compat/linux/...).
I've ben able to run all the Slackware-3.0 binaries I've tried
so far.

Cleanse the SCSI subsystem of its internally defined types
u_int32, u_int16, u_int8, int32, int16, int8.
Use the system defined *_t types instead.
aic7xxx.c:
Fix the reset code.
Instead of queing up all of the SCBs that timeout during timeout
processing, we take the first and have it champion the effort.
Any other scbs that timeout during timeout handling are given
another lifetime to complete in the hopes that once timeout
handing is finished, they will complete normally. If one of
these SCBs times out a second time, we panic and Justin tries
again.
The other major change is to queue flag aborted SCBs during timeout
handling, and "ahc_done" them all at once as soon as we have the
controller back into a sane state. Calling ahc_done any earlier
will cause the SCSI subsystem to toss the command right back at
us and the attempt to queue the command will conflict with what
the timeout routine is trying to accomplish.
The aic7xxx driver will now respond to bus resets initiated by
other devices.
