we were holding a reference (ie: pointer) to a sp<DisplayDevice>
while processing the message. Meanwhile the object itself could
go away and we would end up accessing a dead object.

the root cause of the problem is that we are accessing mDisplays[]
in a few places outside of the main thread.

This change adds a transaction flag for WindowManager to indicate that a
transaction is being used to animate windows around the screen.  SurfaceFlinger
will not allow more than one of these transactions to be outstanding at a time
to prevent the animation "frames" from being dropped.

The screenshot is a GL_RGB texture, and the GL_REPLACE texture env
mode uses vertex alpha for GL_RGB textures instead of alpha=1.0.

This change makes BufferQueue::dequeueBuffer release its mutex before
allocating new buffers.  This should alleviate lock contention in
SurfaceFlinger where SF's main thread can get blocked waiting for an allocation
operation to complete.

Two issues:

(1) We were announcing the hotplug event before we were ready to
handle blank/unblank events, so we were losing the initial unblank
that power manager sends us when HDMI is first plugged in.  This
left the display blank until you toggled the device power off/on.

(2) We were retaining fbTargetHandle for HDMI after the display was
disconnected.  The value didn't get updated when HDMI was reconnected
because the display was blank, so we didn't go through that code
path.  So, when HDMI was re-connected, we passed stale data into
the HWC.

this should be handled by the display-manager. we were doing
that in SF because until recently we didn't have enough support
in the HAL. however, this is now causing other problems when
plugging hdmi while the screen is off for instance.

error codes are returned in errno, this caused ::waitForwever()
to only wait for 1 second and return improper error code (-1).

This needs the ConsumerBase mutex locked, but wasn't locking it. Two
of the four places that called it already held the lock so were fine.
Now addReleaseFence() takes the lock itself, and I added
addReleaseFenceLocked() for the two already-locked callers, since in
one of them dropping the lock would be inconvenient.

The CleanSpec is missing parens, which causes $P to be interpreted as a
single variable, and the following printed to the log:

Clean step: rm -rf RODUCT_OUT/obj/SHARED_LIBRARIES/libgui_intermediates

This patch adds parens as needed.
