This change is porting of following commits related to MDP3
1) SurfaceFlinger: Change to support framebuffer flip for 2D blitters
- Surfaceflinger does not flip framebuffers when there are
no layers marked for HWC_FRAMEBUFFER
- This change checks for the HWC_BLIT flag and will request a flip
to a new FB_TARGET buffer even if there are no FRAMEBUFFER layers
"Change-Id: I1cb44389a05c9ec049d7f0d39c288feccb11a91c"
2) SF: Avoid wormhole clear for BLIT calls
- Do not call GPU clear from SF when composition
type is BLIT as it'll be taken care in HAL.
"Change-Id: Ia613eb9b824c6484ecc8c8fa4ee883545d8541b8"
3) surfaceflinger: Allow gpu to render widevine level3
- Allow gpu to render widevine level3 but keep
blocking screen shots.

Add DisplayUtils class which uses the custom implementations
of ExLayer, ExSurfaceFlinger, ExHWComposer,
and ExVirtualDisplaySurface classes if needed

This tracks fds when layers are created and destroyed in an effort to
determine which specific app (if any) is active when fds are leaked

Enables clang and C++11 for libui/libgui/surfaceflinger, and
eliminates all compile-time warnings.

(cherry picked from commit f10c46ef85)
This change watches for a MAX_VIRTUAL_DISPLAY_DIMENSION value, which
will be set (if necessary) in BoardConfig.mk. If the value is set,
any virtual displays that have a width or a height greater than that
dimension will bypass the hardware composer HAL and be handled only
by SurfaceFlinger.

This forces all SurfaceFlinger sources to be recompiled when the
Makefile changes; that's overkill sometimes but makes sure everything
gets recompiled when compile options (or similar) changes.

This is necessary to use C11/C++11 stdlib atomics, which the next
change will do. This change also fixes a couple bits of syntax that
both GCC and Clang refuse to compile in -std=c++11 mode.

VSYNC power hints are now sent via binder to IPowerManager.
SurfaceFlinger no longer loads a second copy of the PowerHAL.
VSYNC power hints are sent in batches and not on per frame basis.

Individual devices may need to force surfaceflinger to compile for
32-bit if they don't have 64-bit GL libraries.

When this boardconfig is defined, even when all virtual display
composition is done by GLES, the HWC will be forced to copy from the
GLES framebuffer to the output buffer. On some hardware this allows
HWC to do format conversions that would otherwise have to be done by
the consumer, with worse power and/or performance.

This change allows SurfaceFlinger to run at a different vsync phase offset from
that used by external listeners.
Bug: 11175503
Change-Id: I561c53a5659fa6dc1e3e4ae30340f3c1a6adceb4
This change adds a new thread for calling HWComposer's eventControl
asynchronously. The DispSync-based vsync approach ends up enabling and
disabling HWComposer's vsync callbacks at arbitrary times, and some HWComposer
implementations do not have these calls optimized.

This change adds the DispSync class, which models the hardware vsync event
times to allow vsync event callbacks to be done at an arbitrary phase offset
from the hardware vsync. This can be used to reduce the minimum latency from
Choreographer wake-up to on-screen image presentation.

This is an attempt at improving the experience of
users with color vision impairement.
At this time this feature can only be enabled for
debugging:
adb shell service call SurfaceFlinger 1014 i32 PARAM
with PARAM:
0 : disabled
1 : protanomaly/protanopia simulation
2 : deuteranomaly/deuteranopia simulation
3 : tritanopia/tritanomaly simulation
11, 12, 13: same as above w/ attempted correction/enhancement
The enhancement algorithm tries to spread the "error"
such that tones that would otherwise appear similar can be
distinguished.

SF can spawn threads (indirectly) during initialization
and we want those to be spawned at URGENT_DISPLAY_PRIORITY
(in theory they should set their own, but some code lives
in vendor libraries and doesn't).

it used to spawn its own thread and return the main thread
to the binder thread pool -- this was confusing the naming
of things in the kernel.

the main reason for doing this is so that we can have
access to informations about a texture (like its dimension)
close to where we generate and use shaders in ES 2.0.
Previously, there wasn't any way to get to a texture's size
from a RenderEngine implementation.

this is the first step of a series of improvements to
BufferQueue. A few things happen in this change:
- setSynchronousMode() goes away as well as the SynchronousModeAllowed flag
- BufferQueue now defaults to (what used to be) synchronous mode
- a new "controlled by app" flag is passed when creating consumers and producers
those flags are used to put the BufferQueue in a mode where it
will never block if both flags are set. This is achieved by:
- returning an error from dequeueBuffer() if it would block
- making sure a buffer is always available by replacing
the previous buffer with the new one in queueBuffer()
(note: this is similar to what asynchrnous mode used to be)
Note: in this change EGL's swap-interval 0 is broken; this will be
fixed in another change.

this is the first step to add support for GLES 2.x, this
change breaks the dependency of SF on GLES 1.x by moving
all operation into their own class.
