onInitializeDisplays() was posting a transaction with changes
to the display projection. Unfortunately, it only set the
display orientation field and left viewport and frame
uninitialized.
The uninitialized values flowed downstream and found themselves
baked into a bogus DisplayDevice mGlobalTransform. That transform
was then applied to some Rects which were turned into Regions
that were them combined with other Regions.
Under certain situations, the uninitialized data might have
a largish value, resulting in the creation of Regions with
components in excess of the Region max-value limit of 0x7ffffff
(note that this is not INT_MAX). Later when performing a
binary operation using the Region, the Spanner would loop
indefinitely trying to figure out how to stuff a humongous
region inside of a max-value region. Not content to try
just once, the Spanner would continue trying again and
again, pegging the CPU and hanging surface flinger during boot.
Insanity soon followed.

The ComposerService object wasn't watching for SurfaceFlinger
restarts, which doesn't usually matter because the app framework
restarts when SurfaceFlinger dies. However, mediaserver continues
to run, which means its ComposerService object was trying to use
a dead handle, and playback of DRM movies was failing.
This adds a DeathRecipient listener and some logic to re-establish
the SurfaceFlinger connection.

This change moves some common fence handling code into the base class for
BufferQueue consumer classes. It also makes the ConsumerBase class initialize
a buffer slot's fence with the acquire fence every time a buffer is acquired.

This change adds support for the EGL_ANDROID_native_fence_sync extension to the
Android EGL layer. It also fixes a couple minor issues with the extension spec.

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().

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().

This change updates the extension spec to refer to generic "native fence sync
objects" rather than "Android fence sync objects."

- the library is dlopened from libsurfaceflinger
- the library built only when libnativehelper exists

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.

We used to keep the bounds of the region as a
separate rectangle. Instead we now store it as the last
element of the Vector<> of Rects.
This has the benefit of being slightly more efficient when
copying regions and reduces the overhead of small regions,
but more importantly will allow us to export the underlaying
SharedBuffer (eventually).

since regions are copy-on-write, this prevents to
duplicate the region entirely and offseting by 0,0 is
fairly common.

This change adds some infrastructure for testing the BufferQueue class. It
also includes a test that tests the new check in BufferQueue::acquireBuffer
that prevents the consumer from acquiring more than one buffer beyond the max
acquired buffer count that was set.

This change disables the CpuConsumer tests because they require a Gralloc
format that is not supported on all devices.

This change adds an error check to ensure that consumers don't acquire more
buffers than the maximum that they set.
Change-Id: I026643564bde52732e4ee6146972b207ddbbba77
This change makes BufferQueue derive the min undequeued buffer count from a max
acquired buffer count that is set by the consumer. This value may be set at
any time that a producer is not connected to the BufferQueue rather than at
BufferQueue construction time.
