Factor out USB mouse and keyboard detection logic.
Reject USB keyboards which have mouse alike HID items
in their HID descriptors.

Supermicro LCD screen modules seem to not support accessing reports through
the control pipes, but working fine with the interrupt pipes.

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.

The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.
Import the rest of HID improvements from the branch:
- improve report descriptor parser in libusbhid to handle several kinds of
reports same time;
- add to the libusbhid API two functions wrapping respective kernel IOCTLs
for reading and writing reports;
- tune uhid IOCTL interface to allow reading and writing arbitrary report,
when multiple supported by the device;
- teach usbhidctl to set output and feature reports;
- make usbhidaction support all the same item names as bhidctl.

coordinates, such as digitizers and touch-screens, leaving these devices
to uhid(4) and user-level. Specially patched xf86-input-mouse driver can
handle them, that isn't done and can't be done properly with ums(4)
because of mouse(4) protocol limitations.

Back in 2009 I changed the ABI of the GIO_KEYMAP and PIO_KEYMAP ioctls
to support wide characters. I created a patch to add ABI compatibility
for the old calls, but I didn't get any feedback to that.
It seems now people are upgrading from 8 to 9 they experience this
issue, so add it anyway.
system timer is stopped during shutdown and that the pause() statement in ukbd
causes infinite hang in this regard. The fix is to use mi_switch() instead of
pause() to do the required task switch to ensure that the required USB processes
get executed.

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.

The driver is stub. It just creates device entry and feeds
reassembled packets from hardware into it.
If in future we would port wsmouse(4) from NetBSD, or make
sysmouse(4) to support absolute motion events, then the driver
can be extended to act as system mouse. Meanwhile, it just
presents a /dev/uep0, that can be utilized by X driver, that
I am going to commit to ports tree soon.
The name for the driver is chosen to be the same as in NetBSD,
however, due to different USB stacks this driver isn't a port.
