1) "google" sensors are now reporting AOSP as the vendor string
2) don't expose the system's sensor fusion if the HAL provides it
3) use uncalibrated gyro if availble for the system's sensor fusion

If an invalid display device is detected during surface composition
(e.g., a simulated secondary display is removed), abort the
composition.

until now it was only used to discard a layer entirely.
we're now reducing the size of the layer if it is still
visible, if possible.
this works for instance when a surfaceView is used and
only the menu bar is displayed over it.

this allows us to render into a buffer with a
pixelformat of our own choice; this is much faster
on all platform.

colorize a bit the output of dumpsys SurfaceFlinger to
make it easier to read. Right now it will bold the
title of each section and use green for the name of
each layer.

Auto disabled sensors get auto disabled after trigger.
An activation after this wasn't working because the
state was not being reset.

this mimics the code we used for the size. basically we need to
also update the "current state" because it gets copied to the
"drawing state" when a transaction occurs, and it would
"undo" our change.

1. Some sensors can wake up the AP. Add wakelocks.
2. Handle backward compatibility for rotation vector
heading accuracy.
3. Cleanup auto disabled sensors.
4. Fix race condition between enable and dispatch.

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.

When the screen is turned off, the current stack is set to -1. This causes
logic in iSurfaceFlinger's handleTransactionLocked() function to fail to
match the current stack, and the latest orientation is not set into the
layer. This causes BufferQueue, later, to potentially set an obsolete
transformHint on a created surface (such as in the case with ImageWallpaper's
Egl surface, in the bug below).
The fix is to note this situation and use a default value for the DisplayDevice,
which should have the current orientation information.
Issue #8508397 ImageWallpaper sometimes rendered in wrong orientation causing a ~30-40% drop in graphics performance

SF transactions were always handled on VSYNC which allowed
the screenshot to sneak-in between closing the transaction
and vsync (before it's latched), resulting in a screenshot
with the previous state.
we now always force transactions to happen immediately
before screenhots.

HWComposer queries the HWC for dimensions of physical displays, but
can't do that for virtual displays. The dimensions are used to set the
display frame of the framebuffer target layer passed to HWC, and
implicitly the dimensions of the virtual display.

since the transparent region hint really depends on the
content of the window containing the SurfaceView
(it's calculated by the view hierarchy based on
overlapping views), it makes sense to latch it only when
the content of the window (the app) changes.
This should help fixing drawing artifacts when changing the
layout of a window containing a SurfaceView.

We now detect at runtime which sync features to use, which
allows us to remove a lot of the compile-time configuration
options. There is still one option though, to disable
KHR_fence_sync on some devices (which are more efficient
without it).
- added a backdoor to get the vendor's EGL strings
the new logic is:
- use always ANDROID_native_fence_sync if available
- fallback to KHR_fence_sync if available and not disabled
by the compile-time option
- use KHR_wait_sync if available and either of the above is
enabled

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.

If we're using a HWC that doesn't support virtual displays, or we have
more virtual displays than HWC supports concurrently, the
VirtualDisplaySurface should simply be a passthrough from source
(GLES) to sink.
This change also tries to distinguish between display types and HWC
display IDs a little better, though there's more to do here. Probably
needs a higher-level rethink; it's too error-prone now.

HWComposer didn't allow the virtual display output buffer to be set
directly, instead it always used the framebuffer target buffer.
DisplayDevice was only providing the framebuffer release fence to
DisplaySurfaces after a commit.
This change fixes both of these, so both HWComposer and DisplayDevice
should continue to work if VirtualDisplaySurface changes to use
separate framebuffer and output buffers. It's also more correct since
VirtualDisplaySurface uses the correct release fence when queueing the
buffer to the sink.

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

Previously we only queued a virtual display buffer to the sink when
the next frame was about to be displayed. This may delay the "last"
frame of an animation indefinitely. Now we queue the buffer as soon as
HWC set() returns and gives us the release fence.

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.
