passed to the HWComposer.

Bug: 5049148
Finished stylus support, including support for indirect stylus
and mouse tools.
Added TILT axis. When stylus tilt X/Y is available, it is transformed
into an orientation and tilt inclination which is a more convenient
representation and a simpler extension to the exiting API.
Touch devices now only report touch data using a single input
source. Previously touch devices in pointer mode would report
both absolute touch pad data and cooked pointer gestures.
Now we just pick one. The touch device switches modes as needed
when the focused application enables/disables pointer gestures.
This change greatly simplifies the code and reduces the load
on the input dispatcher.
Fixed an incorrect assumption that the value of ABS_(MT_)DISTANCE
would be zero whenever the stylus was in direct contact. It appears
that the correct way to determine whether the stylus is in direct
contact (rather than hovering) is by checking for a non-zero
reported pressure.
Added code to read the initial state of tool buttons and axis values
when the input devices are initialized or reset. This fixes
problems where the input mapper state might have the wrong initial
state.
Moved responsibility for cancelling pending inputs (keys down,
touches, etc.) to the InputDispatcher by sending it a device reset
notification. This frees the InputReader from having to synthesize
events during reset, which was cumbersome and somewhat brittle
to begin with.
Consolidated more of the common accumulator logic from
SingleTouchInputMapper and MultiTouchInputMapper into
TouchInputMapper.
Improved the PointerLocation output.

This change fixes the NATIVE_WINDOW_QUEUES_TO_WINDOW_COMPOSER query of
Surface and SurfaceTextureClient. Surface now uses the inherited
SurfaceTextureClient implementation of this query. SurfaceTextureClient
now queries SurfaceFlinger to determine whether buffers that are queued
to its ISurfaceTexture will be sent to SurfaceFlinger (as opposed to
some other process).

we were not reseting mCurrentTexture in some situations
which in turn caused dequeueBuffers() return a
"FREE" buffer that was also current.
Very often it was harmless, but it created a race with
updateTexImage() which could cause the following
queueBuffers() to fail.

we would leak a weakref_impl if a RefBase was never incWeak()'ed.
there was also a dangling pointer that would cause memory corruption
and double-delete when a custom destroyer was used to delay the
execution of ~RefBase.
it turns out that the custom destroyer feature caused most of the
problems, so it's now gone. The only client was SurfaceFlinger
who now handles things on its own.
RefBase is essentially back its "gingerbread" state, but the
code was slightly cleaned-up.

* changes:
fix a crasher in SurfaceTexture::updateTexImage()
rework dequeueBuffer()'s main loop.
error out when SurfaceTexture APIs are called while not connected
we now make sure to drain the buffer queue on disconnect.
this happens only when in synchrnous mode. in async mode
we clear all buffers except the head of the queue.
for extra safety we also catch the null pointer
in updateTexImage (which should never happen) and return
an error.

Bug: 5064702
Introduced the concept of an InputListener to further decouple
the InputReader from the InputDispatcher. The InputListener
exposes just the minimum interface that the InputReader needs
to communicate with the outside world. The InputReader
passes arguments to the InputListener by reference, which makes
it easy to queue them up.
Consolidated all of the InputReader locks into one simple global
Mutex. The reason this wasn't done before was due to potential
re-entrance in outbound calls to the InputDispatcher. To fix this,
the InputReader now queues up all of the events it wants to send
using a QueuedInputListener, then flushes them outside of the
critical section after all of the event processing is finished.
Removing all of the InputMapper locks greatly simplifies the
implementation.
Added tests for new stylus features such as buttons, tool types,
and hovering.
Added some helpers to BitSet32 to handle common code patterns
like finding the first marked bit and clearing it.
Fixed a bug in VelocityTracker where the wrong pointer trace
could get cleared when handling ACTION_POINTER_DOWN. Oops.
Changed PointerCoords so it no longer stores useless zero
axis values. Removed editAxisValue because it is not very
useful when all zero value axes are absent and therefore
cannot be edited in place.
Added dispatch of stylus hover events.
Added support for distance and tool types.

When querying switch state for a given device id, ensure that the device
exposes the given switch in its capabilities, report AKEY_STATE_UNKNOWN
otherwise.
This fix a bug in InputManager that reports an incorrect switch state
(down) when a device exposes at least one switch in its capabilites and
another switch is queried. For example, this can leads in always
reporting LID state open (SW_LID down) if only SW_HEADPHONE_INSERT is
exposed in capabilities.

The built-in ZipFile class was quite a long time to find an unpack
libraries. Move everything to using the libutils ZipFileRO class that
goes quite a bit faster. Initial measurements are 6 times faster than
the Java code.
Also, read files off the disk and compare their CRC against the APK's
CRC to see if we need to write the new file to disk. This also cuts down
the bootup time by up to a second per APK that has native files.

Adding SurfaceEncoder which can be used to encode
custom frame data. In a sense, it is reverse
of what SurfaceTexture does.
SurfaceEncoder takes in frames from a native window and
passes them to an encoder, thus acting like a MediaSource.
It uses GRAlloc buffers underneath for passing data.
The client side sets the geometry, format in the beginning,
which cannot be changed while the recording is going on.
Currently, there is no common pixel format that both
GRAlloc and HAL understand.
Also, the encoder cannot encode using the data from the GRAlloc
buffers.
The SurfaceEncoder_test examines mainly the buffer passage
since true encoding cannot be done at this point.
SimpleDummyRecorder 'reads' the frames in the same thread
as the start(), whereas DummyRecorder 'reads' in a separate
thread much like the MPEG4Writer. The test with DummyRecorder
is much closer to the real encoding implementation.

This change fixes how the Android EGL layer overrides the size and
format of an ANativeWindow in eglCreateWindowSurface. The new behavior
is to leave the size untouched when overriding the format. The previous
behavior was to reset the ANativeWindow to use the default size set by
the ANativeWindow implementation.
It also adds two new 'perform' methods to the ANativeWindow interface:
set_buffers_dimensions and set_buffers_format, and redefines the
behavior of set_buffers_geometry to be the combination of these two new
methods.
Additionally, this change adds an error check for the return value of
the new native_window_set_buffers_format call, which required adding a
(stub) handler for to FramebufferNativeWindow.

This is intended to absorb the cost of the IPC

full blown ones are two orders of magnitude slower.

not purged upon global permission changes.

This change alters the conditions under which the onFrameAvailable
callback gets called by the C++ SurfaceTexture class. The new behavior
is to call the callback whenever a frame gets queued that will be
visible to the buffer consumer. This means that buffers queued in
synchronous mode always trigger the callback, as those buffers will
remain pending until they are consumed. Buffers queued in asynchronous
mode will only trigger the callback if there was not previously an
unconsumed buffer pending.
The new behavior means that a consumer should perform a draw operation
exactly once for every onFrameAvailable call that it recieves. This
change also modifies SurfaceFlinger and the SurfaceTexture JNI to
support of the new behavior.
