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.

with this change DimLayers will behave just like any other layer,
in particular they'll respect the layer transformations.

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.

This changes the ANativeWindow API and the two implementations to reset
the window's crop rectangle to be uncropped when the window's buffer
geometry is changed.

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.

We used to guarantee that a layer in SurfaceFlinger would never be
destroyed before all references (to its ISurface) on the client
side would be released. At some point, this guarantee got
relaxed to allow to free gralloc resources sooner. This last
change was incorrect, because:
- in implementations with reference-counting the gralloc resources
wouldn't be released anyways, until all the mapping were gone
- in implementations without ref counting, the client side
would most likely crash or do something bad
- it also caused the SharedBufferStack slot to be reallocated
to another surface, which could be problematic if the client
continued to use the surface after the window manager destroyed it.
So, we essentially reinstate the guarantee that layers won't be
destroyed until after all references to their ISurface are
released.
NOTE: This doesn't entirely fix 3306150 because there is another
problem there where the Browser continues to use a surface after it
has been destroyed.

the crop as well as buffer orientation can change at every frame, when that happens
we need to reset the hwc HAL (ie: set the GEOMETRY_CHANGED flag).
currently we achieve this by taking the same code path than an actual geometry change
which is a bit more heavy than necessary.

This change fixes a horrible hack that I did to allow application
processes to create GraphicBuffer objects by making a binder call to
SurfaceFlinger. This change introduces a new binder interface
specifically for doing this, and does it in such a way that
SurfaceFlinger will maintain a reference to the buffers until the app is
done with them.

This change adds a new binder method to the ISurfaceComposer interface.
This IPC is intended to allow SurfaceFlinger clients to allocate gralloc
buffers using SurfaceFlinger as a proxy to gralloc.

while we're waiting for the real fix in the gralloc/gpu driver,
this workaround should resolve the issue.
we make sure to call compositionComplete after everytime we do
composition with the GPU (even for the screenshot case), which is
where the buffer locks are released.

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.

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.

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.

For multiple reason, this effect is not maintainable and was never
used due to its abysmal performance. it'll be resurected when it can be
implemented efficiently.

[3253328, 3171580] Treat GONE and INVISIBLE views the same when calculating transparent regions
[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.

This change removes an optimization from SurfaceFlinger that skipped
composition when it got window updates that had an empty dirty region.
This optimization caused problems because it would skip the hwcomposer
set call, which could leave the window's previous frame buffer bound to
an overlay plane. When the application subsequently dequeued and tried
to lock its next buffer (which would be the buffer currently bound to
the overlay), the lock call would block until the next hwcomposer set
call (which may never happen).
