7174a491bc Improve touch event resampling.
Fixed a few bugs related to the id-to-index mapping for
pointer coordinates.

Tightened the bounds on the resampling time interval to
avoid predicting too far into the future.

Only lerp X and Y components of motion events.

Alter the future to satisfy past predictions.  (Rewrite touch
events to conceal obvious discontinuities.)

Added a system property to control whether resampling is enabled
for debugging purposes.

9f25b7fdf2 Request key maps from input manager service.
Instead of each application loading the KeyCharacterMap from
the file system, get them from the input manager service as
part of the InputDevice object.

Refactored InputManager to be a proper singleton instead of
having a bunch of static methods.

InputManager now maintains a cache of all InputDevice objects
that it has loaded.  Currently we never invalidate the cache
which can cause InputDevice to return stale motion ranges if
the device is reconfigured.  This will be fixed in a future change.

Added a fake InputDevice with ID -1 to represent the virtual keyboard.

e38fdfae91 Add a unique input device descriptor.
The purpose of the input device descriptor is to make it possible
to associate persistent settings for each input device, such as the
keyboard layout.

The descriptor is a hash of the information we have about the
device, such as its vendor id, product id, unique id, name,
or location.

2b6c32ca41 Fix spurious ANRs in native activities.
Some native activities experienced ANRs when the input consumer
deferred an input event due to client-side batching.  If the
input channel was fully emptied then the client had no way of
knowing that it should wake up to handle the deferred input event.

This patch also fixes some lock issues in the native activity
input queue implementation.  In at least one error case, it
was possible for a function to exit without releasing the lock.
