This change makes the Layer::onRemoved method call
SurfaceTextures::abandon on the layer's SurfaceTexture. This will cause
all client-initiated operations on the SurfaceTexture to fail. In
particular, this will result in an error on the client side, rather than
a deadlock when removing a layer that used a SurfaceTexture in
synchronous mode.

Bug: 5020874
This change fixes a bug where the window visibility would be computed
before any buffers were available, causing the window to be treated as
non-opaque. When the first buffer arrived, if both mCurrentOpacity and
the opacity determined by the buffer's format were 'opaque', a
recomputation of the opacity would not be done, and the window would
continue to be treated as non-opaque. SurfaceFlinger could then
unnecessarily draw fully occluded layers.

this will allow implementations who don't support the exact formats
defined in the HAL to work properly.

This change alters the conditions under which the onFrameAvailable
callback gets called by the C++ SurfaceTexture class. The new behavior
is to call the callback whenever a frame gets queued that will be
visible to the buffer consumer. This means that buffers queued in
synchronous mode always trigger the callback, as those buffers will
remain pending until they are consumed. Buffers queued in asynchronous
mode will only trigger the callback if there was not previously an
unconsumed buffer pending.
The new behavior means that a consumer should perform a draw operation
exactly once for every onFrameAvailable call that it recieves. This
change also modifies SurfaceFlinger and the SurfaceTexture JNI to
support of the new behavior.

The transaction flags were atomically read-and-cleared to determine if
a transaction was needed, in the later case, mStateLock was taken to
keep the current state still during the transaction. This left a small
window open, where a layer could be removed after the transaction flags
were checked but before the transaction was started holding the lock.
In that situation eTraversalNeeded would be set but only seen during the
next transaction cycle; however, because we're handling this transaction
(because of another flag) it will be commited, "loosing" the information
about the layer being removed -- so when the next transaction cycle due
to eTraversalNeeded starts, it won't notice that layers have been removed
and won't populated the ditchedLayers array.

Client::mLayers could be accessed from different threads.
On one side from Client::attachLayer() which is currently
called from a binder thread; on the other side from
Client::detachLayer() which is always called from the main
thread.
This could lead to a corruption of Client::mLayers.
We fix this issue by adding an internal lock to Client.

Without that lock, there is a chance of race condition
where while composing a specific index, requestBuf with
the same index can be executed and touch the
same data that is being used in initEglImage.
(e.g. dirty flag in texture)
This leak was intentional, it was there to deal with the fact that
some gralloc implementations don't track buffer handles with
file-descriptors so buffers needed to stay alive until there were
registered, which is not guaranteed by binder transactions.
In this new implementation, we use a small BBinder holding a
reference to the buffer, which with tuck into the parcel. This forces
the reference to stay alive until the parcel is destroyed, which
is guaranteed (by construction) to happen after the buffer is
registered.
this allows the public facing API to not expose the previous hack.

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.

Generally we never want to lock a buffer for write access if it is at
the "head" on the surfaceflinger side. The only exception (1) is when
the buffer is not currently in use AND there is at least one queued
buffer -- in which case, SurfaceFlinger will never use said buffer
anymore, because on the next composition around, it will be able to
retire the first queued buffer.
The logic above relies on SurfaceFlinger always retiring
and locking a buffer before composition -- unfortunately this
didn't happen during a screenshot.
This could leave us in a situation where a buffer is locked by the
application for write, and used by SurfaceFlinger for texturing,
causing a hang.
Here, we fix this issue by never assuming the exception (1), it was
intended as an optimization allowing ANativeWindow::lockBuffer() to
return sooner and was justified when most of SF composition was
done in software. The actual buffer locking is now ensured by
gralloc. We could have handled screenshots in a similar way to
a regular composition, but it could have caused glitches on screen,
essentially, taking a screenshot could cause to skip a frame.
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.
also improve SurfaceFlinger 'dumpsys' log
list the purgatory, which shows windows that have been closed,
but for which the client still has references.
we were not clearing the screen entirely, which caused garbage when
the screen wasn't entirely covered by windows.
