If ACTION_OUTSIDE_EVENTS contain information about whether the touch is
obscured, then a pattern of invisible, untouchable, unfocusable
SYSTEM_ALERT_WINDOWS can be placed across the screen to determine
approximate locations of touch events without the user knowing.

CVE-2017-0860
Due to more complex window layouts resulting in lots of overlapping
windows, the policy around FLAG_WINDOW_IS_OBSCURED has changed to
only be set when the point at which the window was touched is
obscured. Unfortunately, this doesn't prevent tapjacking attacks that
overlay the dialog's text, making a potentially dangerous operation
seem innocuous. To avoid this on particularly sensitive dialogs,
introduce a new flag that really does tell you when your window is
being even partially overlapped.
We aren't exposing this as API since we plan on making the original
flag more robust. This is really a workaround for system dialogs
since we generally know their layout and screen position, and that
they're unlikely to be overlapped by other applications.

Introduce ACTION_BUTTON_PRESS and ACTION_BUTTON_RELEASE as actions to
signal a button press or release. If these actions happen
simulanteously with a DOWN or UP event then they're explicitly
ordered to happen after the DOWN or preceding the UP in order to send
them to the most recently targeted view.
Also, introduce new stylus button constants that differ from the
constants we use for mouse buttons.

Count items as they are added and removed rather than iterating over the
entire list to count them.
Increases performance slightly, particularly when tracing is turned on,
which causes count to be queried more often, and when the number of
items in the queues grow large. This can happen due to applications not
responding, for example.

This code is no longer necessary and was preventing input from
reaching their desired windows. See bug 17648830.

Print more details about the exact reason that an ANR has occurred.
Also start checking that the window actually has a registered
input connection that is not in a broken state. These windows
are supposed to be cleaned up by the window manager promptly
as if the app had crashed but the pattern of ANRs we are observing
suggests that broken windows might be sticking around longer than
they should.

This ensures it's the same size in both 32 and 64 bit
processes and also brings it in line with struct
MotionEntry.

Native doesn't ever actually care about the attributes of keys, so
move all of it up into the managed layer and move all of the key
names down so they're defined once.

Eliminated the bright here and woke here policy flags since they
were unused. Simplified the input dispatch policy somewhat.

Enhanced the input system to support concurrent dispatch of touch
events on multiple displays which is required for this to work.
Add method to apply offset to PointerCoords.

Add all of the underlying input system pieces, minux PointerController and

its own process and the addition of the input HAL.
