HEADSUP new usb code coming in.

After a long period of review and testing I am on the verge of
committing Hans Peter's new usb stack to -current.

The patchset requires a SMALL _493_ line diff to the main code,
mostly bug fixes to arm.  And then a large number of new files
for the usb system.

The new usb system will be committed as separate files with
the intention of folding them over the old files before the
9.0 release.

The diff to the main files is here:
http://mu.org/~bright/usb2/usb2_release_001.diff

The whole diff, including new files is here:
http://mu.org/~bright/usb2/usb4bsd.diff.gz

FAQ:
Q. Has this been reviewed?
A. Yes, pretty strongly by myself and we've consulted with
various others, Warner, Scott and Andrew for review/testing.
I wouldn't say that Warner or Scott have given full review
but just about all questions have been answered.

Q. Can we change the name from "usb2_" to my favorite name?
A. No.   This is for a short period, stop being so annoying.

Q. What about the old usb code?
A. What about it? :D

Q. What about ttys?
A. I don't know, we'll address the mpsafe aspects of ttys shortly,
Hans is very responsive to SMP issues.

Q. Shouldn't you wait?
A. Wait for what?  No.

Q. I have some whitespace nits, can you do those?
A. No.  It's a 100k line diff and a 3meg delta, we tried really hard
to get all whitespace right, but you're welcome to point things out after
the commit.

Thanks!
