ukbd: adjust for SCHEDULER_STOPPED() and overhaul locking code

This change is designed to let USB keyboard work in the panic context
with stop_scheduler_on_panic=1. Most of change consists of removing
mtx_owned() checks where they can be easily avoided. Some additional
lock cleanup is performed along the way.

A list of the smaller changes:
- newbus methods should be executed with Giant already held, just assert
this
- kbd methods called in the non-polling context should be executed with
Giant already held, just assert this
- Giant is recursive, so we should just take it where we must have it,
without redundant checks if we already have it
- thanks to recent syscons changes we don't need to go through the hoops
to detect if kernel is going to poll us; polling mode is now clearly
separated from non-polling mode
- at present the polling mode can be entered by only one thread
- document special cases in greater detail

Please note that the ukbd code and underlying USB code still lve
dangerously in the kdb context by trying to obtain various locks
including the Giant. If any of those locks are already held by the
stopped threads, then the things would blow up.
Another limitation of the ukbd driver is that it is detached before a
system enters the halt state.

With this commit we can enable kern.stop_scheduler_on_panic by default,
that should not introduce any regressions.

usb: change to one-pass probing of device drivers

This brings USB bus more in line with how newbus is supposed to be used.
Also, because of the two-pass probing the following message was produced
by devd in default configuration when almost any USB device was
connected:
Unknown USB device: vendor <> product <> bus <>
This should be fixed now.

Note that many USB device drivers pass some information from probe
method to attach method via ivars. For this to continue working we rely
on the fact that the subr_bus code calls probe method of a winning driver
again before calling its attach method in the case where multiple
drivers claim to support a device. This is done because device
description is set in successful probe methods and we want to get a correct
device description from a winning driver. So now this logic is re-used
for setting ivars too.

Make the newbus subsystem Giant free by adding the new newbus sxlock.
The newbus lock is responsible for protecting newbus internIal structures,
device states and devclass flags. It is necessary to hold it when all
such datas are accessed. For the other operations, softc locking should
ensure enough protection to avoid races.

Newbus lock is automatically held when virtual operations on the device
and bus are invoked when loading the driver or when the suspend/resume
take place. For other 'spourious' operations trying to access/modify
the newbus topology, newbus lock needs to be automatically acquired and
dropped.

For the moment Giant is also acquired in some key point (modules subsystem)
in order to avoid problems before the 8.0 release as module handlers could
make assumptions about it. This Giant locking should go just after
the release happens.

Please keep in mind that the public interface can be expanded in order
to provide more support, if there are really necessities at some point
and also some bugs could arise as long as the patch needs a bit of
further testing.

Bump __FreeBSD_version in order to reflect the newbus lock introduction.
