3f97a0eb09 When usb_event_thread() first starts, wait significantly longer
before starting exploring (4 seconds), and extend the wait period
if new USB buses are attached while waiting.

This works around a problem seen when there is more than one EHCI
controller in the system and you kldload usb.ko after the system
has booted. The problem is that usb.ko contains 3 separate PCI
drivers which get initialised one by one (uhci, ohci, ehci), and
when each driver is initialised, all PCI buses are re-probed after
just the addition of that driver. This means that there can be a
significant delay between the attaching of a companion controller
and the subsequent EHCI attach, so it is possible for the companion
controller's USB 1.x bus to be scanned before the EHCI driver gets
a chance to check if there is really a USB 2.x device connected.

f954f61ba1 Don't defer the boot-time exploration of high-speed USB busses.
This ensures that we explore EHCI busses before their companion
controllers' busses, so that ports connected to full/low speed
devices will be properly routed to the companion controllers by the
time the OHCI/UHCI exploration occurs.

1aa8c25508 Now that all architectures allow hooks to be inserted before
configure_final(), assert that "cold" is true in usb_cold_explore()
when there are busses to explore. When USB is kldloaded after boot,
usb_cold_explore() will still get invoked but the list of busses
to explore in that case should always be empty.

c9756266e6 Defer boot-time exploration of USB busses until all devices in the
system have been attached, but no later. This ensures that we do
not explore ohci or uhci busses before the companion echi controller
has been initialised, so it should fix the problem of multi-speed
USB devices getting attached as USB 1 devices first and then
re-attached as USB 2.

Some further changes are needed on architectures that do not currently
allow hooks to be inserted before configure_final() - alpha, ia64,
powerpc and sparc64. On these architectures the exploration will
now be delayed until the usb kthread runs.

7eade05dfa - Implement selwakeuppri() which allows raising the priority of a
thread being waken up.  The thread waken up can run at a priority as
  high as after tsleep().

- Replace selwakeup()s with selwakeuppri()s and pass appropriate
  priorities.

- Add cv_broadcastpri() which raises the priority of the broadcast
  threads.  Used by selwakeuppri() if collision occurs.

0ae911eb0e Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

    Change the operation of the USB event thread.  Before it only

    tasks for device drivers that need a process context, but don't
