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.

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.

when we validate the surface there, most errors are in fact allowed
because it is legal to cancel a buffer after a surface has been
destroyed (for instance). in that case make sure to not log
error messages as they are very confusing.

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.

This change adds a new binder method to the ISurfaceComposer interface.
This IPC is intended to allow SurfaceFlinger clients to allocate gralloc
buffers using SurfaceFlinger as a proxy to gralloc.

3097475: Animation setting should control the screen on animation
3096779: CRT power-on animation can briefly show the top app instead of lockscreen
There is now a parameter that controls wether the ON and/or OFF animation are
performed. we also always clear the screen to black on power off, to make
sure it won't briefly appear on power on.
HOWEVER, 3096779 is not 100% fixed in the case where we're doing the animation
because there is a race, where SF doesn't wait (b/c it doesn't know) for the
framework to have redrawn the lockscreen.

Bug #3081600
The OpenGL renderer in libhwui uses a single EGL context per process and
thus create it with an RGBA 8888 EGL configuration. To ensure that all
windows are compatible with this configuration, this change modifies
the window manager and SurfaceFlinger.
The window manager now checks the window's flags and if the window is
hardware accelerated, it forces the window's pixel format to be
translucent when creating the surface. The window itself is still
marked as opaque if we know that the window will be opaque on screen.
This keeps existing optimizations in place.
Similarly in SurfaceFlinger, a translucent Surface can now be created
with the Surface.OPAQUE flag, indicating SurfaceFlinger that the surface
does not require blending, despite its RGBA 8888 configuration.

fix [2835280] Add support for cancelling buffers to ANativeWindow
There is a new ANativeWindow::cancelBuffer() API that can be used to
cancel any dequeued buffer, BEFORE it's been enqueued. The buffer is
returned to the list of availlable buffers. dequeue and cancel are not
mutually thread safe, they must be called from the same thread or
external synchronization must be used.

fix [2931513] Add support for setting the orientation of an ANativeWindow
This change makes the camera HAL interface take an ANativeWindow interface from
which all the camera preview buffers will be allocated. The framework code
running in application processes now passes a Surface object rather than an
ISurface to the camera server via Binder when setting the preview surface. The
camera server then forwards that Surface object (which implements the
ANativeWindow interface) to the camera HAL, which uses it to communicate with
SurfaceFlinger to allocate the camera preview buffers.

This change adds a process-global cache of previously deserialized Surface
objects so that if a Surface object wrapping the same ISurface gets received
again the same Surface can be used. This is important because the 'tail'
pointer in the SharedBufferClient is stored only on the client side, and needs
to be the same for all the Surface objects wrapping an ISurface instance. This
solves the problem by making there only be one Surface object wrapping an
ISurface per process.

this is called for each relayout() and used to create a full Surface (cpp)
which in turn did some heavy work (including an IPC with surfaceflinger),
most of the time to destroy it immediatelly when the returned surface
(the one in the parcel) was the same.
we now more intelligentely read from the parcel and construct the new
object only if needed.

SurfaceComposerClient now only exist on the WindowManager side,
the client side uses the new SurfaceClient class, which only
exposes what a client needs.
also instead of keeping mappings from IBinder to SurfaceComposerClients
we have a SurfaceClient per Surface (referring to the same IBinder), this
is made possible by the fact that SurfaceClient is very light.
