eae59d2ea7 Removed dependecies between BufferQueue and SurfaceTexture
Refactored SurfaceTexture and BufferQueue such that share
no protected members.  Created an consumer facing interface
for BufferQueue in preparation of connecting SurfaceTexture
and BufferQueue through a binder.

99ce5cdeb3 separate transactions from updates
with this changes, SF transactions are handled as soon as possible
but do not trigger updates. the update is delayed until the next
vsync.

this allows us to work much better without requiring triple-buffering.

3cf199aef6 fix an issue with vsync event delivery
vsync events were sometimes delivered to connected
client who didn't request them. this happened if
another client requested the delivery and that client
was first in the client list.

also fix the vsync test which didn't request any events as
well as DisplayEventReveiver documentation which was misleading
about the necessity to request vsync events.

478ae5eb5a Improve the VSYNC api a bit.
- add the ability to set the vsync delivery rate, when the rate is
set to N>1 (ie: receive every N vsync), SF process' is woken up for
all of vsync, but clients only see the every N events.

- add the concept of one-shot vsync events, with a call-back
to request the next one. currently the call-back is a binder IPC.

a36bcd53ac attempt to fix bug 5313580
the working theory here is that a Surface object has become non-promotable
because it lost its last reference; later Surface::readFromParcel is called
the previous surface is found in the cache, but can't be promoted. this causes
a new Surface object to be created which will promptly try to connect to the
CPU_API -- this in turn will fail because the previous (now dead) surface is
still connected.

To fix this, we make sure to disconnect from the SurfaceTexture when
Surface[TextureClient] is destroyed.

a929748ddb SurfaceTexture: Fix to return the oldest of free buffers to Client on Dequeue call
Surface Texture dequeue logic is modified to return the oldest of the
free buffers to Client on dequeue call.

Currently dequeue method is returning the first buffer index which is free.
The parsing is done in ascending order of the buffer slot indices.
This leads to returning the buffer which has been just queued to composer,
and hence display, and this defeats the purpose of having minimum dequeue count
as 2 in asynchrnouse mode.

This is fixed by checking all the free slots and returning the oldest buffer.

29b5762efc don't return the current buffer from dequeueBuffer
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.

for extra safety we also catch the null pointer

an error.

bee205fd58 EGL: fix the ANativeWindow size/fmt override
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.

3d8063b02e SurfaceTexture: change onFrameAvailable behavior
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.

c04f153353 Fix a bug where setgeometry couldn't be undone
This change the binder protocol between SurfaceTextureClient
and SurfaceTexture. dequeueBuffer() now takes the requested
parameters for the buffer. SurfaceTexture decides if the
buffer needs to be reallocated and does the allocation
if needed. In that case it returns BUFFER_NEEDS_REALLOCATION
to tell SurfaceTextureClient that it needs to call
requestBuffer (which all parameters have been removed) to
acquire a pointer to the buffer.

dequeueBuffer and requestBuffer could be folded into a single
IPC call, but we chose to optimize the case where buffers are
not created and avoid some complexity in the marshalling code.

41abd67302 frameworks/base: make the ANativeWindow query() method const
query() does not modify the object's data, so it needs to be a const method

4cb18881b5 Fix a GraphicBuffer leak in SurfaceTexture
This leak was intentional, it was there to deal with the fact that
some gralloc implementations don't track buffer handles with
file-descriptors so buffers needed to stay alive until there were
registered, which is not guaranteed by binder transactions.

In this new implementation, we use a small BBinder holding a
reference to the buffer, which with tuck into the parcel. This forces
the reference to stay alive until the parcel is destroyed, which
is guaranteed (by construction) to happen after the buffer is
registered.

this allows the public facing API to not expose the previous hack.

a5c75c0162 SurfaceTexture can now force the client to request a buffer
SurfaceTexture now has the concept of default size a new method,
setDefaultBufferSize() to set it. When the default size is
changed, dequeueBuffer() will return a value telling the
client that it must ask for a new buffer.

The above only applies if the client has not
overriden the buffer size with setGeometry.

1d01a12e71 Add support for timestamps into SurfaceTexture.
API addition: The timestamps are represented as nanoseconds from some
arbitrary time point. Like the SurfaceTexture transform matrix, the
timestamp retrieved by getTimestamp is for the last frame sent to the
GL texture using updateTexImage().

Camera HAL change: Expect vendors to set these timestamps using
native_window_set_buffers_timestamp().  For now, they are
autogenerated by SurfaceTextureClient if set_buffers_timestamp() is
never called, but such timing is likely not accurate enough to pass a
CTS test.

number of buffers that must be left un-dequeued during the steady-state
operation of the ANativeWindow.

1b20cde313 Pass the IGraphicBufferAlloc to SurfaceTextureClient.
This change passes a reference to the IGraphicBufferAlloc binder object
to SurfaceTextureClient objects.  When STC objects are created they
query their associated ISurfaceTexture object for the
IGraphicBufferAlloc that the SurfaceTexture uses to allocate buffers.
Having the SurfaceTextureClient hold this reference prevents the
GraphicBufferAlloc in SurfaceFlinger from freeing the allocated buffers
before the SurfaceTextureClient is done with them.

This change implements the onFrameAvailable callback for the
SurfaceTexture java class.  It includes the C++ SurfaceTexture code as
well as the JNI and Java code to enable the callback.

9a78c90cd4 Fix remote GraphicBuffer allocation in SurfaceFlinger.
This change fixes a horrible hack that I did to allow application
processes to create GraphicBuffer objects by making a binder call to
SurfaceFlinger.  This change introduces a new binder interface
specifically for doing this, and does it in such a way that
SurfaceFlinger will maintain a reference to the buffers until the app is
done with them.

8ba32fade1 Add the SurfaceTexture C++ implementation.
This change adds the C++ implementation of SurfaceTexture and related
classes. The goal of this is for a SurfaceTexture to be passed to
camera service or Stagefright in place of a Surface to allow camera
preview or decoded video frames to be streamed to an OpenGL ES texture
that an application can use.

59abe7e090 Replace epoll() with poll() and rename PollLoop to Looper.
As part of this change, consolidated and cleaned up the Looper API so
that there are fewer distinctions between the NDK and non-NDK declarations
(no need for two callback types, etc.).

Removed the dependence on specific constants from sys/poll.h such as
POLLIN.  Instead looper.h defines events like LOOPER_EVENT_INPUT for
the events that it supports.  That should help make any future
under-the-hood implementation changes easier.

Fixed a couple of compiler warnings along the way.

a48bcf62b6 Added SensorManager.getMinDelay()
Exposed the new "min delay" sensor property through native and
java sensor apis. This allows the caller to know what is the
maximum rate at which a sensor can return events, or, if a sensor
works in "update" mode (events returned only when the value changes).

Also augmented SensorManager.regusterSensorEvent() so that it can
accept a value in microsecond in addition to the 4 constants already
defined.

in this commit:
- implemented the C stub
- implemented the binder interfaces involved
- implemented most of the C++ client side

missing:
- SensorManager cannot connect to the SensorServer yet
(because there is no SensorServer yet)
