Add type to the hid structure to distinguish to which device type
(now only mouse) we are talking to. Needed for per device type ignore
list support.

Note: this patch leaves the type as unknown for bluetooth devices,
there is not support for this in the hidp code.

Commit 8006479c introduced a spinlock in
input_dev->event_lock, which is locked when handling input events.
However, the hid-pidff driver sleeps when handling events as it waits for
reports being sent to the device before changing the report contents
again.
This causes a system lockup when trying to use force feedback with a PID
device, a regression introduced in 2.6.24 and 2.6.23.15.

Fix it by extracting the raw report data from struct hid_report
immediately when hid_submit_report() is called, therefore allowing
drivers to change the contents of struct hid_report immediately without
affecting the already-queued transfer.

In hid-pidff, re-add the removed usbhid_wait_io() to
pidff_erase_effect() instead, to prevent a full report queue from causing
the submission to fail, thus not freeing up device memory.
pidff_erase_effect() is not called while dev->event_lock is held.

Make a bus from hid core. This is the first step for converting all the
quirks and separate almost-drivers into real drivers attached to this bus.

It's implemented to change behaviour in very tiny manner, so that no driver
needs to be changed this time.

Also add generic drivers for both usb and bt into usbhid or hidp
respectively which will bind all non-blacklisted device. Those blacklisted
will be either grabbed by special drivers or by nobody if they are broken at
the very rude base.

Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for
non-laptop Apple keyboards of the Aluminium series. The USB version of
these don't need Numlock emulation, like the laptop (and Aluminium
Wireless) do, as they have a proper keypad.

This patch splits the Numlock emulation for Apple keyboards in a
different quirk flag, so that it can be enabled for all the keyboards
but the Aluminium USB ones.

If the Numlock emulation is enabled for Aluminium USB keyboards, the
JKL and UIO keys become the numeric pad, and the rest of the keyboard
is disabled, included the key used to disable Numlock.

Additionally, these keyboard should not have a Numlock at all, as the
Numlock key is instead replaced by the 'Clear' key as usual for Apple
USB keyboards.

Microsoft's wireless desktop receiver (Model 1028) has a bug in the report
descriptor -- namely, in four seperate places it uses USAGE_MIN and _MAX when
it quite obviously doesn't intend to.

In other words, it reports that it has pretty much _everything_ in 'consumer'
and 'generic desktop'.  And then the X evdev driver believes I have a mouse
with 36 absolute axes and a huge pile of keys and buttons, when I in fact,
should have zero.  255/256 in three of the cases, and 0-1024 in another.

This patch fixes the report descriptor of this device before it enters the HID
parser.
