it's safer this way because this object owns an
EGLSurface which cannot be easily reference-counted.
it also gives us the ability to sub-class it, which
we might want to do soon.

- fix typo drawForSreenshot misspelled
- get rid of DisplayDeviceBase
- removed unused or unneeded code
- always pass a DisplayDevice to Layer methods that are called
on a per-display basis (to make it clear that this could be
called more than once per composition).

Commit 8630320 moved the eglSwapBuffers fallback (for devices with no
HWC implementation) from DisplayHardware to HWComposer. But HWComposer
only knows about the framebuffer EGL display and surface handles if
there is a HWC, so it was always passing bogus handles.
This change moves the eglSwapBuffers fallback up to SurfaceFlinger,
which has access to the framebuffer EGL handles.

we will only ever have a single instance of HWComposer, so
it's now an attribute of SurfaceFlinger, instead of being part
of DisplayHardware.
DisplayHardware now just represents a "display" (it should be renamed).

this attribute can be set through a regular transaction using
SurfaceComposerClient (just like any other attribute, eg: position or size)

no change of functionality -- the old behavior is implemented
on top of this new protocol.
this new protocol will allow, eventually, to pass informations
about displays and layer stacks.

mostly refactored SurfaceFlinger.h, but also removed dead code.
cleaned-up a few includes as well.

Call into the new HWC blank operation to blank or unblank the screen.
Legacy systems may have already blanked the screen via early suspend,
and can choose to not implement the blank operation in their hardware
composer implementation.

- remove dependency on cached state in validateVisibility
- get rid of mVertices and mTransformedBounds
- get rid of validateVisibility
- get rid of unlockPageFlip
- handleTransaction now returns a dirty region
- computevisibileregion now uses window-manager space
both API and implementation will change, this is just a prototype
intended to show feasability.
SurfaceFlinger is passed an ISurfaceTexture through a new
callback, it is in turn used to create an EGLSurface which
surfaceflinger will draw into in addition to the main screen.

After a HWC set, each SurfaceFlinger Layer retrieves the release fence
HWC returned and gives it to the layer's SurfaceTexture. The
SurfaceTexture accumulates the fences into a merged fence until the
next updateTexImage, then passes the merged fence to the BufferQueue
in releaseBuffer.
In a follow-on change, BufferQueue will return the fence along with
the buffer slot in dequeueBuffer. For now, dequeueBuffer waits for the
fence to signal before returning.
The releaseFence default value for BufferQueue::releaseBuffer() is
temporary to avoid transient build breaks with a multi-project
checkin. It'll disappear in the next change.

The desc.txt file can now mark parts as 'must finish cleanly' by using
'c' as the part line prefix rather than 'p'. If so indicated, if the
bootanimation is asked to quit it will do so only after waiting to
finish that part.
I considered either making init.c service killing smarter or promoting
bootanim to be a bindable service with a requestExit method. However,
these changes are probably too big/risky given our ship date. So
I used a property as a mailbox between SurfaceFlinger and bootanim.

When turning the screen off we could have 2 waiters on the
vsync condition: The main vsync waiter as well as one in
onScreenReleased(). We were only signaling the condition though,
so it it would be possible to wake onScreenReleased() without waking
the main vsync thread which would then be stuck in .wait().
We fix this by just using broadcast() when receiving a vsync event.
We also add a broadcast() to signal when the state of
mUseSoftwareVSync changes. This is important particularly for
the transition from hardware to software vsync because the main
vsync waiter might have observed mUseSoftwareVSync == false
and decided to block indefinitely pending a hardware vsync
signal that will never arrive.
Removed a potentially deadlocking wait for a signal in
onScreenReleased(). The function was trying to wait for the last
vsync event from the hardware to be delivered to clients but there
was no guarantee that another thread would signal it to wake up
again afterwards. (As far as I can tell, the only other other
thread that might wake it up at this point would be a client
application issuing a vsync request.) We don't really need to wait
here anyhow. It's enough to set the mUseSoftwareVSync flag,
wake up the thread loop and go. If there was a pending vsync
timestamp from the hardware, then the thread loop will grab
it and use it then start software vsync on the next iteration.

The acquire and release fences aren't yet used; this is just support
for the new version and temporary backwards compatibility for older
versions.

HWComposer must abstract the HWC HAL entirely, so that the
HAL can continue to evolve (and break binary compatibility)
without breaking SurfaceFlinger. The HWC data structure had
leaked outside of HWComposer, this is now fixed.
We now have an abstract interface that provide all the
needed functionality, HWCompose provides concrete
implementations of it based on the the HWC version.

SF now has its own implementation of ANW for the
framebuffer and it uses BufferQueue. FramebufferNativeWindow
is now only used by stand-alone apps.

this would happen when a resize was pending (ie: we have received
and processed a resize transaction but have not received a buffer
with the right size) and a new transaction came in that didn't
involve a resize, for instance a translate-only transaction.
in this case, we would incorrectly update the drawing state
with the pending size, eventhough we still don't have a buffer
for it.
the solution is quite simple, we never allow the size to propagate
from current to drawing state during the regular transaction processing
(unless we are in fixed-size mode -- meaning we don't need to have
a matching size buffer), this propagation happens later once we
receive the buffer.

SurfaceFlinger will no longer directly synchronize with early suspend.
Instead, PowerManagerService will synchronize with SurfaceFlinger to
ensure that a black frame has been drawn on the display, and then
trigger all early suspend handlers.
