this affects devices that need a glReadPixels(). We use
a FBO instead of a GlConsumer as an intermediate render target, this
saves 2 calls to eglMakeCurrent().
On Galaxy Nexus this allows us to go from ~135ms to ~35ms for
recent's screenshots.

DisplayDevices can be released when DisplayManager removes them from
the display list, or (for virtual displays) when the surface is set to
NULL. We were only cleaning up HWC resources associated with the
display in the first case.

some drivers don't support this yet, so we use a system
property to enable the glReadPixels "workaround" for them:
ro.bq.gpu_to_cpu_unsupported=1
Change-Id: I74d6a3a8f0cee8d5a507b72c760cf247e39195e0
We're not using IMemoryHeap as a transport anymore,
instead we're providing a CpuConsumer and use the
IGraphicBufferProducer version of the screenshot API.
However, some GPU drivers don't support properly
a GPU to CPU path, to work around this, we use a
temporary BufferQueue on the server side for the
GL rendering, and we use glReadPixels into the
CpuConsumer (we're now using a CPU to CPU path
which is always supported).
Currently this "wrapping" is always performed,
but it can be bypassed on devices that support
the GPU to CPU path.
This also addresses a DoS attack vector on
SurfaceFlinger, where an application could
consume all of SF's filedescriptors by creating
a lot of screenshots in a row.

the purgatory list wasn't needed anymore; in fact it had no effect as
buffer life-time management is now handled by the BufferQueue.
For QueuesToWindowComposer we keep a list of wp<> on the IBinder
for IGraphicBufferProducers we hand over to clients so we can
easily check if an IGraphicBufferProducer is ours. We clean-up the
list when our IGraphicBufferProducer are destroyed.

ISurface was only used to get the IGraphicBufferProducer from
a Layer. It's now replaced by a BBinder subclass / IBinder and
is only used as a handle to the surface, to both refer to it
and manage its life-time.
Also cleaned-up a bit the ISurfaceComposer interface and
"create layer" code path.
Change-Id: I68d0e02d57b862cffb31d5168c3bc10cea0906eb
The functionality of LayerBase and Layer is folded
into Layer. There wasn't a need for this abstraction
anymore.

- SurfaceFlinger now supports to take a screenshot
directly into an IGraphicBufferProducer
- reimplement the IMemoryHeap screenshot on top
of the above
- reimplement LayerScreenshot such that its
BufferQueue is directly used as the destination
of the screenshot. LayerScreenshot is now a thin
wrapper around Layer

SurfaceFlinger generated that included window animation transaction changes.

The C++ class names don't match what the classes do, so rename
ISurfaceTexture to IGraphicBufferProducer, and SurfaceTexture to
GLConsumer.

For hotpluggable builtin displays (currently just HDMI), create the
display device IBinder token when the display is connected and destroy
it when the display is disconnected. Previously we created the tokens
at startup and never changed them. This made it so that when comparing
current and drawing state, we couldn't tell whether a display had been
disconnected and reconnected.

we were holding a reference (ie: pointer) to a sp<DisplayDevice>
while processing the message. Meanwhile the object itself could
go away and we would end up accessing a dead object.
the root cause of the problem is that we are accessing mDisplays[]
in a few places outside of the main thread.

This change adds a transaction flag for WindowManager to indicate that a
transaction is being used to animate windows around the screen. SurfaceFlinger
will not allow more than one of these transactions to be outstanding at a time
to prevent the animation "frames" from being dropped.

- onScreenAcquired/Released now takes a display

we now make sure to take the blanked state of a display into
account when we build its list of visible layers, this ensures
that we won't call prepare/set with a non-empty list when the
display is blanked.

physical displays (as opposed to virtual displays such as wifi displays).

Use only display tokens in the API to refer to new displays.
Don't require the caller to specify the display when creating
a surface (since in general a surface could be shown on
any display).
This is intended to be a minimum change just to update the API.
Note that SurfaceFlinger still uses DisplayID in a few places
internally that might cause some features not to work properly
when there are multiple displays (LayerScreenshot, for example).

in EGL. this fixes that.

fix a few bugs with external displays
- HWComposer doesn't really handle multiple displays yet
so there is a lot of ugliness there
- We also need to make sure that external displays are not
blanked by default
- due to some EGL limitations surfaces being swapped need
to be current

it's safer this way because this object owns an
EGLSurface which cannot be easily reference-counted.
it also gives us the ability to sub-class it, which
we might want to do soon.
