7a4d0dfd43 SurfaceFlinger: Respect the PROTECTED gralloc bit.
This change makes SurfaceFlinger treat layers for which the active
buffer has the GRALLOC_USAGE_PROTECTED bit set as if they have the
'secure' flag set.

a1f47b90ab fix a surface leak in SurfaceFlinger
SF kept a strong reference to ISurface until the
window manager removed the surface from the screen.
This fell appart when running standalone tests, that is
when the window manager wasn't involved.

When the window manager is around, it would clean-up surfaces
even when an application died.

with this change, SF is able to do its own cleanup without
relying on the window manager.

the change is very simple, we simply don't keep a reference
to ISurface and make sure no more than one of them can
be created.

ac45e6bff1 Correctly handle translucency of device-specific pixel formats
Check requested format for device-specific formats, and assume (as
documented in libhardware/include/hardware/hardware.h) this is opaque
layer so no blending is necessary.

3cc2677efc fix [3389263] OMX.Nvidia.h264.decode fails to shutdown
We were still destroying an ANativeWindow's buffer pretty soon
after it was removed from the window manager. This time
we really wait for the ISurace to go away.

2bd1d95efe clean-up unneeded code
now that we removed the notion of a "inUse" buffer in surfaceflinger
a lot of code can be simplified / removed.

noteworthy, the whole concept of "unlockClient" wrt. "compositionComplete"
is also gone.

420a283c4d Fix a problem where hwc and GL composition could show a different buffer
if a surface's buffers are reallocated, the current active buffer will
end-up pointing on one of these until a new buffer is retired.

we're now keeping a reference to the actual buffer until we retire a
new one.

da9584dc29 fix [3223749] media server crashes when switching mode from video capture to still image capture
there was an issue were in some situation SF would call prepare() on hwc
with a NULL handle and never call prepare again.
in this situation, we onw set the SKIP flag to make sure that hwc
won't process this layer and as soon as we receive our first buffer we
trigger a recompute of the visible regions which will end-up calling
prepare() again.

dd17b3eaa9 fix [3176642] Camera preview turns completely black for multiple toggles between camera and camcorder app
There was a leak of Surface tokens when a surface was detached from a UserClient.
We now always detach a surface from its client before attaching to the new one,
this guarantees that its token is freed.

733189d408 [3171580] Fix two typos related to fixed-size buffers
mFixedSize was never set, this bug was introduced during some "cleanup", in
practice this could cause some issues when a fixed-size buffer was used and
the window was resized.

Layer::drawForSreenShot() had a typo that had no effect.

mFixedSize was used to determine if filtering was needed, which was a bit too
conservative and created a dependency between filtering and "fixed size" states
which should exist.

Now we enable filtering based on the size of the buffer vs. the size of the layer.

3b996c96e4 Always create OpenGL accelerated windows in RGBA 8888.
Bug 

The OpenGL renderer in libhwui uses a single EGL context per process and
thus create it with an RGBA 8888 EGL configuration. To ensure that all
windows are compatible with this configuration, this change modifies
the window manager and SurfaceFlinger.

The window manager now checks the window's flags and if the window is
hardware accelerated, it forces the window's pixel format to be
translucent when creating the surface. The window itself is still
marked as opaque if we know that the window will be opaque on screen.
This keeps existing optimizations in place.

Similarly in SurfaceFlinger, a translucent Surface can now be created
with the Surface.OPAQUE flag, indicating SurfaceFlinger that the surface
does not require blending, despite its RGBA 8888 configuration.

208cb07724 fix [2873058] Surface::dequeueBuffer blocks on last buffer, i.e. cannot dequeue all allocated buffers at once.
this situation happened when the last buffer needed to be resized
(or allocated, the first time). the assumption was that the buffer
was in use by SF itself as the current buffer (obviously, this
assumption made no sense when the buffer had never been allocated, btw).

the system would wait until some other buffer became the "front" buffer.

we fix this problem by entirely removing the requirement that the
buffer being resized cannot be the front buffer. instead, we just
allocate a new buffer and replace the front buffer by the new one.

the downside is that this uses more memory (an extra buffer) for a
brief amount of time while the old buffer is being reallocated and
before it has actually been replaced.
