This adds partial support for the Maschine controller by Native Instruments.
Supported now are the 1x1 MIDI interface and the 41 buttons, 11 endless
rotary encoders, and 16 pressure-sensitive drum pads. Still to work on are the
dimmable LEDs and the two monochrome screens.

There was a case where a newly-registered input device could be opened before
a necessary variable in the device structure was set. When code tried to use
the variable in the URB reply callback, it would cause an Oops.

This fix sets the aforementioned variable before calling input_register_device.

This patch adds support for the new Traktor Kontrol S4 by Native
Instruments. It features a new audio data streaming model, MIDI
in and out ports, a huge number of 174 dimmable LEDs, 96 buttons
and 46 absolute encoder axis, including some rotary encoders.

All features are supported by the driver now.

Did some code refactoring along the way.

This device does not have audio controllers and backlit buttons only.
Input data is handled over a dedicated USB endpoint.

All functions are supported by the driver now.

This header file exists only for some hacks to adapt alsa-driver
tree.  It's useless for building in the kernel.  Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it.  This should be really killed in
future.

 - added support for all input controllers on Native Instrument's 'Kore
   controller'.
 - added ALSA controls to switch LEDs on 'RigKontrol 2', 'RigKontrol3',
   'Audio Kontrol 1' and 'Kore controller'.
 - added ALSA controls to switch input mode, software lock and ground
   lift features on 'Audio 8 DJ'.

 - link input device with its parent so that it placed in proper spot
   in sysfs hierarchy
 - drivers that allow changing their keymaps should use private copy
   of the keymap so that one instance of a device does not affect
   another instance
 - it is preferred for drivers to properly set up input_dev->phys to
   help userspace locate devices
 - drivers should use usb_to_input_id(), or perform endianess conversion,
   themselves, otherwise ID is not correct on big-endian boxes
 - whitespace and formatting cleanup

get rid of input BIT* duplicate defines

use newly global defined macros for input layer. Also remove includes of
input.h from non-input sources only for BIT macro definiton. Define the
macro temporarily in local manner, all those local definitons will be
removed further in this patchset (to not break bisecting).
BIT macro will be globally defined (1<<x)

input_free_device()'s comment says:
input_free_device() should only be used if input_register_device() was
not called yet or if it failed. Once device was registered
use input_unregister_device() and memory will be freed once last
refrence to the device is dropped.
