BufferQueueInterposer allows a client to tap into a
IGraphicBufferProducer-based buffer queue, and modify buffers as they
pass from producer to consumer. VirtualDisplaySurface uses this to
layer HWC composition on top of GLES composition before passing the
buffer to the virtual display consumer.

DisplayDevice now has a DisplaySurface instead of using
FramebufferSurface directly. FramebufferSurface implements
DisplaySurface, and so does the new VirtualDisplaySurface class.
DisplayDevice now always has a surface, not just for virtual displays.
In this change VirtualDisplaySurface is just a stub; buffers still go
directly from GLES to the final consumer.

None of these should change behavior, except for removing some
incorrect log messages when using a virtual display.
- HWComposer::getAndResetReleaseFenceFd() checks the HWC version, so
no need to do that in the DisplayDevice::onSwapBuffersCompleted().
However, it should check that mFramebufferSurface is not NULL like
it is for virtual displays.
- Comment that FramebufferSurface::dump() overrides the non-virtual
ConsumerBase::dump(), and fix it so the right thing happens
regardless of the static type of the pointer/reference the callee
has. FramebufferSurface::dump() could be removed right now, but I'd
need to bring it back in a later change.
- Use the right enum for validating display type ids.
- Don't try to send hotplug events for virtual displays.
- Mark virtual displays as connected so HWComposer::prepare() doesn't
think something is wrong when it gets a non-NULL layer list.
- Remove unused FramebufferSurface methods.

The functionality of LayerBase and Layer is folded
into Layer. There wasn't a need for this abstraction
anymore.

This change eliminates the uses of a NULL sp<Fence> indicating that no waiting
is required. Instead we use a non-NULL but invalid Fence object for which the
wait methods will return immediately.

This change adds functionality to the HWComposer class to track the retire
fences returned by each hwc set call. It adds the HWComposer::getDisplayFence
method to allow other parts of SurfaceFlinger to get a fence that will signal
when the most recent flip takes effect on a display.

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().

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.

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.

getDisplayInfo() now returns proper information for
HWC managed displays.
hotplug is sitll not supported; so this is not fully correct
as the information returned will be bogus if the HDMI screen
is not plugged in.

connected to a hardware composer).

the problem was that LayerBase::setPerFrameData() was always setting
this flag. in fact there was no reason to do this at that point since
the layer is initialized to a default state in setGeometry().

If SurfaceFlinger needs to refresh the screen but the dirty region is
empty, it won't set the layer acquire fences, and stale file
descriptors will be passed to HWC commit(). Now we make sure to clear
the stale file descriptors for each layer right after commit().

we used to have a visibleRegion object per layer, but now
it's per screen; so at somepoint the code got changed to
calculate the per-screen visible region on the stack and that's
what got passed to HWC.
we're now setting the visibleRegionScreen at each frame and
freeing at after the HWC set() call. We use the underlaying
SharedBuffer so that in most cases we don't have to allocate,
free or copy memory around.

default, which prevented the boot animation from appearing
(unless you got lucky with the hardware composer state).
