Huge merge from NetBSD:

usbdi.c (1.61):
	===================================================================
	revision 1.61
	date: 2000/01/31 20:13:07;  author: augustss;  lines: +20 -4
	Change the way the HC done method is invoked a little.
	===================================================================

usbdi.c (1.65):
	===================================================================
	revision 1.65
	date: 2000/03/08 15:34:10;  author: augustss;  lines: +4 -2
	Get the status right when a polled transfer times out.
	===================================================================

ohci.c (1.79), uhci.c (1.89), uhcivar.h (1.24), usb_port.h (1.22),
usbdivar.h (1.48):
	===================================================================
	date: 2000/03/23 07:01:46;  author: thorpej;
	New callout mechanism with two major improvements over the old
	timeout()/untimeout() API:
	- Clients supply callout handle storage, thus eliminating problems of
	  resource allocation.
	- Insertion and removal of callouts is constant time, important as
	  this facility is used quite a lot in the kernel.

	The old timeout()/untimeout() API has been removed from the kernel.
	===================================================================

uhci.c (1.80), usbdi.c (1.66):
	===================================================================
	date: 2000/03/23 18:59:10;  author: thorpej;
	Shake out some bugs from the callout changes.
	===================================================================

ohci.c (1.80), uhci.c (1.91), uhcivar.h (1.25), usb_port.h (1.23),
usbdi.c (1.67), usbdivar.h (1.49):
	===================================================================
	date: 2000/03/24 22:03:30;  author: augustss;
	Some cleanup and renaming of the callouts used in USB drivers.
	===================================================================

uhci.c (1.92), uhcivar.h (1.26):
	===================================================================
	date: 2000/03/24 22:57:58;  author: augustss;
	Two major changes:

	  Make each xfer have its own intr_info.  This is necessary if we want
	  to queue multiple xfers on an endpoint.  This should get rid of the
	  (mostly harmless) DIAGNOSTICs about intr_infos (not) being done.

	  Change (again!) how xfers are aborted.  Aborting a TD is a nightmare
	  on the braindead UHCI controller.  (Unless you stop the HC, thereby
	  losing isoc traffic.)  Hopefully I got it right this time.
	===================================================================

usbdivar.h (1.50):
	===================================================================
	revision 1.50
	date: 2000/03/25 00:10:19;  author: augustss;  lines: +4 -2
	GC an unsued field and add some DIAGNOSTIC in xfer.
	===================================================================

ums.c: Use the callout functions instead of the timeout ones.

	===================================================================
	revision 1.93
	date: 2000/03/25 00:11:21;  author: augustss;

uhci.c (1.94), usbdivar.h (1.51):
	===================================================================
	date: 2000/03/25 07:13:05;  author: augustss;
	More DIAGNOSTIC.
	Initialize a callout handle I forgot.
	===================================================================

	===================================================================
	revision 1.100
	date: 2000/03/27 09:41:36;  author: augustss;  lines: +13 -3
	Don't mess with QH in bulk abort for the moment.
	===================================================================

uhci.c (1.102):
	===================================================================
	revision 1.102
	date: 2000/03/27 22:42:57;  author: augustss;  lines: +66 -26

uhci.c (1.103):
	===================================================================
	date: 2000/03/28 09:47:10;  author: augustss;  lines: +11 -1
	Another patch for xfer abort...
	XXX The current xfer queueing and aborting semantics should really
	XXX be changed.  It cannot be implemented in a sane way on UHCI.
	XXX One day when I have lots of time I'll redesign it...
	===================================================================

uhci.c (1.104): Correct a debug message.
uhci.c (1.105): Be more defensive in a DIAGNOSTIC test.

	===================================================================
	revision 1.106
	date: 2000/03/29 01:49:13;  author: augustss;  lines: +14 -309
	*SIGH*  Revert back to the old method of aborting xfers.
	I had tested the new stuff for two months now, but as soon as I commited
	it the problems started to appear.  Murphy, no doubt...
	===================================================================

usb_subr.c (1.70), usbdi.c (1.71), usbdivar.h (1.53):

	revision 1.70
	date: 2000/03/29 01:45:20;  author: augustss;  lines: +2 -1
	Do not accept new xfers for queuing while a pipe is aborting.
