Only initiate fallback key handling if the first key down was
not handled and there is no other fallback key already in progress.
This prevents spurious fallbacks from being generated when
applications handle the initial down but not repeated downs or the up.

Added support for tracking the mouse position even when the mouse button
is not pressed. To avoid confusing existing applications, mouse movements
are reported using the new ACTION_HOVER_MOVE action when the mouse button
is not pressed.
Added some more plumbing for the scroll wheel axes. The values are
reported to Views but they are not yet handled by the framework.

The touch screen sometimes reports more than 10 pointers even though that's
all we asked for. When this happens, we start dropping events with more
than 10 pointers. This confuses applications and causes them to crash.
Raised the limit to 16 pointers.
Bug: 3331247
The default behavior was to identify all touch devices as touch screens.
External devices that are plugged in are more likely to be touch pads
not attached to a screen. Changed the default to be a touch pad
and renamed some internal constants to avoid confusion.
A certain mouse happens to also behave like a touch pad. That caused
problems because we would see multiple concurrent traces of motion events
coming from the same input device so we would batch them up.
Added code to ensure that we don't batch events unless they come from
the same *source* in addition to coming from the same *device*.
Due to batching or misbehaving drivers, it's possible for the set of
pointer ids to be different from what we expect when it comes time to
split motion events across windows. As a result, we can generate motion
events with 0 pointers. When we try to deliver those events, we cause
an error in the InputTransport so we tear down the InputChannel and kill
the application.
Added code to check out assumption about pointer ids and drop the
event gracefully instead.
Patched up the tests to take into account the change in default behavior
for identifying touch screens and touch pads.

This change implements two heuristics.
1. When events are older than 10 seconds, they are dropped.
2. If the application is currently busy processing an event and
the user touches a window belonging to a different application
then we drop the currently queued events so the other application
can start processing the gesture immediately.
Note that the system takes care of synthesizing cancelation events
automatically for any events that it drops.
Added some new handle types to allow the native dispatcher to
indirectly refer to the WindowManager's window state and app window
token. This was done to enable the dispatcher to identify the
application to which each window belongs but it also eliminates
some lookup tables and linear searches through the window list
on each key press.

Reject movements from other devices when one device is already down.
This fixes jittery behavior when the user moves the mouse and touches
the screen at the same time.

Added support for loading the pointer icon from a resource.
Moved the system server related bits of the input manager out
of libui and into libinput since they do not need to be linked into
applications.
