Kill SPLUSBCHECK -- it's not portable, and quite annoying on some

platforms which otherwise function just fine.

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.

Change the internal API to allow DMA buffers to be pre-allocated by
...
the device driver instead of happening automagically in the HC driver.
This affects both the HC-USBD interface as well as the USBD-device
interface.
This change will allow DMA buffers to be reused e.g. in isochronous
traffic.
Add isochronous support to the UHCI driver (not for OHCI yet).

Get rid of a bunch of code that was part of an old USBDI proposal, but that
...
is unused in our USB stack.
Once upon a time, when I started writing the USB stack for NetBSD, there
was an effort to make a standard for how USB device drivers should interact
with the rest of the USB stack. This effort had contributors from just
about all Un*x camps (but not Micro$oft :). I based my design on one of their
early proposals since I thought it would be a good idea if we could all
share device drivers with a minimum effort. Shortly after I started my work
all the free Un*x people were thrown out of the USBDI work since we did not
pay the USB membership fee. Well, some time has passed now and the work of
the standardization group is almost public again. But alas, the new standard
has grown to be a monster! I do not want to have this as the basis for the
*BSD USB stack; it is far too complicated.
So, since we are not even close to being compilant with the standard, I've
thrown out some old baggage.

Rework the way ukbd attaches itself as the console (again). We now allow
...
the code to pick the first USB keyboard instance as the console, ignoring
which USB controller it's on. Should eventually allow detaching of the
console keyboard.

Add a way for machine-dependent code to tell a USB controller that it
...
has the console input device. The USB keyboard driver uses this to
attach the first USB keyboard instance as the console keyboard.
Unfortunately, this must still be deferred to autoconfiguration time,
but there's not much we can do about that right now.
