Now that input_free_device is basically an alias for input_put_device
we need to acquire a reference to input module right when we allocate
device because input_dev_release releases reference to input module
unconditionally.

Microsoft Natural Elite Pro keyboard produces unisual response to

2-byte response). Fail GET ID command so atkbd gets a change to
do alternate probe.

ports simply disabling MUX mode is safe solution.

- Use the touch status bit rather than the pressure bits to
distinguish a BTN_TOUCH event. Non-pressure-sensitive touchscreens
always report full pressure
- Report ABS_PRESSURE information only if the touchscreen supports it

Implement a new force feedback interface, in which all non-driver-specific
operations are separated to a common module. This includes handling effect
type validations, locking, etc.
The effects are now file descriptor specific instead of the previous strange
half-process half-fd specific behaviour. The effect memory of devices is not
emptied if the root user opens and closes the device while another user is
using effects. This is a minor change and most likely no force feedback
aware programs are affected by this negatively.
Otherwise the userspace interface is left unaltered.

The start() method need to be called every time we create

Create input_inject_event() function which is to be used by input
handlers as opposed to input_event() which is reserved for drivers
implementing input devices. The difference is that if device is
"grabbed" by some process input_inject_event() will ignore events
unless sent from the handle that is currently owns the device.

The new start() method is called immediately after connect() and also
when "grabbed" device is released by its owner. This will allow input
handlers to re-synchronize state of once-grabbed device with the rest
of devices.

With the new interrupt rework, an interrupt "host" map() callback can be
called after the interrupt is already active.
It's called again for an already mapped interrupt to allow changing the
trigger setup, and currently this is not guarded with a test of wether
the interrupt is requested or not.
I plan to change some of this logic to be a bit less lenient against
random reconfiguring of live interrupts but just not yet.
The ported MPIC driver has a bug where when that happens, it will mask
the interrupt. This changes it to preserve the previous masking of the
interrupt instead.
