displays.

b4b1730abb only use glReadPixels() when needed when taking screenshots
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

abe815dd69 rework how we take screenshots for a CPU consumer
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.

6710604286 get rid of purgatory and fix QueuesToWindowComposer query
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.

4d9b822e2c get rid of ISurface
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.

2a9fc493df rework screenshot API and implementation
- 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

692c723e84 Create builtin display tokens on demand
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.

db9b41fd15 fix a corruption in blank/unblank
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.

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.

9d4e3d2f42 Banish DisplayID from the SurfaceFlinger API.
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).

34a09ba1ef Move eglSwapBuffers out of HWComposer
Commit 8630320 moved the eglSwapBuffers fallback (for devices with no
HWC implementation) from DisplayHardware to HWComposer. But HWComposer
only knows about the framebuffer EGL display and surface handles if
there is a HWC, so it was always passing bogus handles.

This change moves the eglSwapBuffers fallback up to SurfaceFlinger,
which has access to the framebuffer EGL handles.
