target knows enough to run a 'chflags -R 0' and a second 'rm' if the first
'rm' ran into any errors while removing files.

- When adding new waiting threads to the waitlist for an object,
use INSERT_LIST_TAIL() instead of INSERT_LIST_HEAD() so that new
waiters go at the end of the list instead of the beginning. When we
wake up a synchronization object, only the first waiter is awakened,
and this needs to be the first thread that actually waited on the object.
- Correct missing semicolon in INSERT_LIST_TAIL() macro.
- Implement lookaside lists correctly. Note that the Am1771 driver
uses lookaside lists to manage shared memory (i.e. DMAable) buffers
by specifying its own alloc and free routines. The Microsoft documentation
says you should avoid doing this, but apparently this did not deter
the developers at AMD from doing it anyway.
With these changes (which are the result of two straight days of almost
non-stop debugging), I think I finally have the object/thread handling
semantics implemented correctly. The Am1771 driver no longer crashes
unexpectedly during association or bringing the interface up.
1) Include string.h for strcpy.
2) Don't make duplicate declaration of dump_file, we now include extern.h.
3) Help out with some constness.
4) Cast to slightly better types in some comparisons.

devices will be detected as follows:

0x3f7,0x3f4-0x3f5,0x3f2-0x3f3,0x3f0-0x3f1 irq 6 drq 2 on acpi0
To do this, we find the minimum and maximum start addresses for the
resources and use them as the base for the IO and control ports.

read EOF from STDIN_FILENO, write zero bytes into the pseudo-terminal;
this is interpreted as an EOF by the program being scripted.
I've tested this with two non-interactive scripts:

# echo bar | xargs script foo echo
and one interactive program:
