c701401f8c Allow disabling layer rotation during screenshots
Add the ability to ignore layers' transformation matrices during
screenshot capture, which will allow the window manager to capture
unrotated images for recents during the device rotation animation.

3ca76f416b remove support for glReadPixels screenshot path
this was only needed on some chipset we're not
supporting in KLP.

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.

041a075262 don't allow screenshots without the READ_FRAMEBUFFER permission
the recent screenshot rework allowed the older screenshot
interface to work without that permission

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

2adaf04fab Rename ISurfaceTexture and SurfaceTexture
The C++ class names don't match what the classes do, so rename
ISurfaceTexture to IGraphicBufferProducer, and SurfaceTexture to
GLConsumer.

dd3cb84cfb SurfaceFlinger: add support for secure displays
This change adds support for displays that are not allowed to display surfaces
with the eSecure flag set.  All non-virtual displays are considered secure,
while virtual displays have their secure-ness specified at creation time.

2d5e230292 SurfaceFlinger: add animation transactions
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.

This allows us to blank and unblank displays other than the built-in
display (e.g. HDMI).

8dfa92fef9 Plumb display name into SurfaceFlinger
The Surface createDisplay() call takes a display name for debugging.
This change carries it through SurfaceFlinger and displays it in
the "dumpsys SurfaceFlinger" output.

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).

8b33f03232 update SF binder protocol to support setting display attributes
no change of functionality -- the old behavior is implemented
on top of this new protocol.
this new protocol will allow, eventually, to pass informations
about displays and layer stacks.

3094df359d First prototype atttempting to support an external display
both API and implementation will change, this is just a prototype
intended to show feasability.

SurfaceFlinger is passed an ISurfaceTexture through a new
callback, it is in turn used to create an EGLSurface which
surfaceflinger will draw into in addition to the main screen.

8e533069e5 surfaceflinger: replace early suspend with binder call from PowerManager
SurfaceFlinger will no longer directly synchronize with early suspend.
Instead, PowerManagerService will synchronize with SurfaceFlinger to
ensure that a black frame has been drawn on the display, and then
trigger all early suspend handlers.

f15a83f581 SurfaceFlinger: add a crop to the layer state
This change adds a crop rectangle specified in window coordinates to the layer
state.  The all window pixels outside this crop rectangle are treated as though
they were fully transparent.  This change also adds the plumbing necessary for
WindowManager to set that crop.
