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.

ab10c5804c Recompute visible regions more vigorously
Some of the code in latchBuffer was calling invalidateHwcGeometry,
but that didn't cause the SurfaceFlinger visible region code to
re-evaluate the layer's visibility.  Set the recomputeVisibleRegions
"out" parameter instead.

3941cb240d SurfaceTexture: default to doing GL sync
This change makes updateTexImage default to performing the necessary
synchronization and adds an argument for SurfaceFlinger to disable that
synchronization so that it can be performed lazily.

b0d1dd36f1 Reshuffle FramebufferSurface
FramebufferSurface no longer speaks directly to the FB HAL.  Now
everything goes through HWComposer (which may or may not be
connected to a hardware composer).

Added display index arg to some query methods.

61e04b92bd SurfaceTexture: use eglWaitSync
This change adds a compile-option to use eglWaitSyncANDROID to ensure that
texturing operations that access the current buffer of a SurfaceTexture do not
occur until the buffer is completely written.  It also moves this
synchronization into a new SurfaceTexture method called doGLFenceWait and
changes SurfaceFlinger's Layer class to use that method rather than performing
its own wait on the fence.

c397360883 the visible region sent to HWC was garbage
we used to have a visibleRegion object per layer, but now
it's per screen; so at somepoint the code got changed to
calculate the per-screen visible region on the stack and that's
what got passed to HWC.

we're now setting the visibleRegionScreen at each frame and
freeing at after the HWC set() call. We use the underlaying
SharedBuffer so that in most cases we don't have to allocate,
free or copy memory around.

31a353da22 BufferQueue: clean up buffer counting
This change is a clean up of some of the handling of the maximum number of
buffers that are allowed at once.  It mostly renames a few member variables and
methods, but it includes a couple small refactorings.

4297734c11 turn DisplayDevice into a reference-counted object
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.

ef19414bd8 Transfer HWC release fences to BufferQueue
After a HWC set, each SurfaceFlinger Layer retrieves the release fence
HWC returned and gives it to the layer's SurfaceTexture. The
SurfaceTexture accumulates the fences into a merged fence until the
next updateTexImage, then passes the merged fence to the BufferQueue
in releaseBuffer.

In a follow-on change, BufferQueue will return the fence along with
the buffer slot in dequeueBuffer. For now, dequeueBuffer waits for the
fence to signal before returning.

The releaseFence default value for BufferQueue::releaseBuffer() is
temporary to avoid transient build breaks with a multi-project
checkin. It'll disappear in the next change.

3e8b853d67 refactor HWComposer to break dependency with the HAL headers
HWComposer must abstract the HWC HAL entirely, so that the
HAL can continue to evolve (and break binary compatibility)
without breaking SurfaceFlinger. The HWC data structure had
leaked outside of HWComposer, this is now fixed.

We now have an abstract interface that provide all the
needed functionality, HWCompose provides concrete
implementations of it based on the the HWC version.

0cd545f142 sometimes we would incorrectly scale the content of a surface
this would happen when a resize was pending (ie: we have received
and processed a resize transaction but have not received a buffer
with the right size) and a new transaction came in that didn't
involve a resize, for instance a translate-only transaction.

in this case, we would incorrectly update the drawing state
with the pending size, eventhough we still don't have a buffer
for it.

the solution is quite simple, we never allow the size to propagate
from current to drawing state during the regular transaction processing
(unless we are in fixed-size mode -- meaning we don't need to have
a matching size buffer), this propagation happens later once we
receive the buffer.

4824d40a35 sometimes SF would not process a surface resize
this would happen when a window started with size A, was
resized to B and immediately resized to A. In this situation
the erquested and active size would be the same, and SF
would think a transaction wasn't needed.

we fix this by always comparing the requested sizes.

Also, make sure to set mRefreshPending once we're sure
we have succesfully called updateTexImage().

05cec9d127 improve resize transactions
use a flag instead of pre-committing the "requested" state
to prevent propagation or "requested" to "active", which makes
things a lot clearer when reading the code.

also avoid going through the "resized" code-path when requested
size is equal to "active" size.
