If we switched from HWC to GLES but the dirty region was empty
(could happen if the dirty region is outside of the screen for instance), we
need to force a full screen composition.
In this change we ignore the dirty region for the purpose of
rejecting the whole update and we rely on the fact that it will later
be expanded to the whole screen. This was the least risky fix.

we perform external display clipping only on the GL
side (ie: not done on the h/w composer side, which is
harder and would be too risky). in practice this means
that WFD will be clipped properly, while HDMI *may* or
may not depending on how hwc is used.

with the eSecure flag set. All non-virtual displays are considered secure,
while virtual displays have their secure-ness specified at creation time.

The code that reserves display IDs was only run when a hardware
composer was present. The eventControl() function, which handles
enabling of vsync, was ignoring the request because the primary
display didn't appear in its set of allocated IDs. This moves
reservation of IDs for built-in displays outside the HWC-only block.
Also, added a couple of warnings in eventControl().

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.

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.

When a display is disconnected, removing it from SurfaceFlinger's
display list is non-atomic with removing it from the Display Manager
and any in-flight transactions. So SurfaceFlinger might get a display
state change transaction for a display it has already forgotten about.
Just ignore these.

The display was being removed from SurfaceFlinger's list before we
had a chance to reset HWComposer's layer list, so we were passing
stale data into the hardware composer (which has its own per-display
data). This resulted in "invalid gralloc handle" complaints.
We now clear the layer list immediately after removing the display.
The display was being removed while its EGLSurface was still
"current", resulting in "cancelBuffer: BufferQueue has been
abandoned" complaints. We now call makeCurrent on the primary
display before removing the external display.

This change makes SurfaceFlinger reset the acquire fence fd to -1 after each
call to HWComposer::commit. The HWComposer implementation is resonsible for
closing the fd, so SurfaceFlinger should make sure not to pass it to HWC
multiple times.

Bug: 7234237
Some of the code in latchBuffer was calling invalidateHwcGeometry,
but that didn't cause the SurfaceFlinger visible region code to
re-evaluate the layer's visibility. Set the recomputeVisibleRegions
"out" parameter instead.
Bug 7235797
Change-Id: If6ba33fbd1a594cd64cc5253aebf752d6ceda1c9
The transparent region hint is computed only from view layout
locations, ignoring post-layout translation. If a SurfaceView is layed
out with no other views above it, but a view is moved above it
post-layout, that view's layout bounds would be subtracted from the
window's transparent region instead of its drawing bounds. Prior to
this change, the view would not be visible (except where its layout
bounds and drawing bounds overlap).
With this change, composition uses visible regions computed without
regard to the transparent regions. However, if all of a layer's
visible region is transparent, it will be removed from the list of
layers to composite. This doesn't fix the root problem of incorrect
transparent regions, and doesn't prevent bad composition in all cases.
But it does avoid it for some existing apps, whiel still allowing the
transparent region hint to save power in the important
fullscreen-video-in-a-SurfaceView case.
