When creating a new file using open(..., O_CREAT), it is an error
to fail to specify a creation mode. If a mode is not specified, a
random stack provided value is used as the "mode".
This will become a compile error in a future Android change.

For comparison purposes, port the legacy velocity tracker

This algorithm better tolerates certain kinds of errors in the
touch input than the least squares strategy but it may underestimate
the velocity of accelerating movements. This algorithm is
mainly of interest as a baseline for testing and comparison with the
least squares algorithm, which remains the default.

This change is very useful for testing purposes because it makes it
easy to compare different implementations to see how they behave.
There is no change to the current default strategy.

Some input devices do not generate ACTION_MOVE events while all
pointers have stopped, thereby lulling the VelocityTracker into
a false sense of complacency. Before handling the following sample,
reset the VelocityTracker state so as not to be influenced by
earlier samples before the pointer stopped. The velocity after
stopping is assumed to be discontinuous.

VelocityTracker was implicitly assuming that the pointer ids in
a MotionEvent were ordered. That is not necessarily the case
so we need to be careful while copying the pointer coordinates out.

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.

The window manager policy made some incorrect assumptions about the
meaning of the Configuration.keyboard field. We need to be more
careful about distinguishing between built-in and external keyboards.
Most of this change is to move the determination of the parts of
the Configuration related to input devices into the WindowManagerService
leveraging new features of the InputManagerService to good effect.
Then we plumb through the flag that indicates whether a device
is internal or external so that we can be more particular about
how the lid switch effects changes to the Configuration.

Changed the English US keymaps to implement a strict US key map
with no additional ALT functions.
Fixed a bug copying the alias in the InputDevice copy constructor.
Added support for end of line comments in KCM and KL files.
Added the German keyboard layout.
Sorted the keys in the keyboard layout files by physical arrangement
to make it easier to maintain them.

Bluetooth devices can be renamed by the user. Make the
input system aware of the user-specified name and transparently
pass it down to applications. This enables the keyboard
layout picker Settings UI to use device names that are
consistent with what the user set in the Bluetooth UI.

Automatically choose a default value for the 'number' property
based on the characters that the key can generate.
Don't generate any character when ctrl, alt or meta is
pressed unless the behavior exactly matches the modifier keys
that are pressed.
Simplified the basic keyboard layouts taking into account the
new features.

Added support for mapping both scan codes and HID usages to
KeyLayoutMap and KeyCharacterMap. Keyboard overlays can
now influence how key events are mapped to key codes.

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.

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.

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.

Added handling for EV_MSC / MSC_SCAN which typically reports
the HID usage associated with a key. This will enable key maps
to map keys with HID usages that Linux does not natively recognize.
Removed keyCode and flags fields from EventHub RawEvent since
they don't necessarily make sense in isolation now that we
pay attention to HID usage codes too.
Removed the fallback code for mapping keys and axes. In practice,
an input device should be self-sufficient. We should not ever
need to look at the built-in keyboard's key map. In fact, there
usually isn't a built-in keyboard anyhow. This code was originally
working around a problem where we weren't loading the key map
for touch screens with virtual keys, which has long since been fixed.

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.

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.

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.
