6ec6f79e1a Support loading keyboard layout overlays from resources.
Added the concept of a keyboard layout overlay, which is
a key character map file that has "type OVERLAY".

Added support for loading keyboard layout overlays from
resources dynamically.  The layouts are reloaded whenever they
are changed in the Settings application or an application
is installed.  This is somewhat more aggressive than necessary
so we might want to optimize it later.

Before system-ready, the input system uses just the generic
keyboard layouts that are included on the device system image.
After system-ready, it considers the user's selected keyboard
layout overlay and attempts to load it as necessary.  We need to
wait until system-ready before doing this because we need to
be in a state where it is safe to start applications or access
their resources.

a47425a13c Add support for input devices that have vibrators.
Added a getVibrator() method to InputDevice which returns a Vibrator
associated with that input device.  Its uses the same API as the
system vibrator which makes it easy for applications to be modified
to use one or the other.

af9e8d3818 Notify applications when input devices change.
This change allows the InputManager to keep track of what input
devices are registered with the system and when they change.
It needs to do this so that it can properly clear its cache of
input device properties (especially the key map!) when changes
occur.

Added new API so that applications can register listeners for
input device changes.

Fixed a minor bug in EventHub where it didn't handle EPOLLHUP
properly so it would spam the log about unsupposed epoll events
until inotify noticed that the device was gone and removed it.

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.

ac14351e16 Move some APIs from window manager to input manager.
Simplified input injection API down to just one call.

Removed all input state reading API.  It was only used by the
window manager policy and required a permission that applications
could not obtain.  READ_INPUT_STATE is now unused and deprecated.

4532e61584 Refactor input system into its own service.
Extracted the input system from the window manager service into
a new input manager service.  This will make it easier to
offer new input-related features to applications.

Cleaned up the input manager service JNI layer somewhat to get rid
of all of the unnecessary checks for whether the input manager
had been initialized.  Simplified the callback layer as well.
