0029c66203 Add input filter mechanism for accessibility.
This patch adds a mechanism for capturing, filtering, transforming
and injecting input events at a very low level before the input
dispatcher attempts to deliver them to applications.  At this time,
the mechanism is only intended to be used by the accessibility
system to implement built-in system-level accessibility affordances.

The accessibility input filter is currently just a stub.
It logs the input events receives and reinjects them unchanged,
except that it transforms KEYCODE_Q into KEYCODE_Z.

Currently, the accessibility input filter is installed whenever
accessibility is enabled.  We'll probably want to change that
so it only enables the input filter when a screen reader is
installed and we want touch exploration.

a454767b09 Get key repeat timeout and delay from ViewConfiguration.
Replaces previously hardcoded values.  This ensures that key repeat
takes the accessibility long press timeout setting into account.

Unfortunately the system must be rebooted for the change to take
effect.  We will fix that later.

56194ebec6 Wake screen from external HID peripherals.
Added some plumbing to enable the policy to intercept motion
events when the screen is off to handle wakeup if needed.

Added a basic concept of an external device to limit the scope
of the wakeup policy to external devices only.  The wakeup policy
for internal devices should be based on explicit rules such as
policy flags in key layout files.

Moved isTouchEvent to native.

Ensure the dispatcher sends the right event type to userActivity
for non-touch pointer events like HOVER_MOVE and SCROLL.

05dc66ada6 Fade out the mouse pointer after inactivity or other events.
Fades out the mouse pointer:
- after 15 seconds of inactivity normally
- after 3 seconds of inactivity in lights out mode
- after a non-modifier key down
- after a touch down

Extended the native Looper to support enqueuing time delayed
messages.  This is used by the PointerController to control
pointer fade timing.
