FramebufferSurface no longer speaks directly to the FB HAL. Now
everything goes through HWComposer (which may or may not be
connected to a hardware composer).
Added display index arg to some query methods.

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.

HWComposer can now create IDs representing a display
it can deal with. IDs MAIN and HDMI are reserved.
SurfaceFlinger associate HWComposer IDs with a
DisplayDevice and uses that when it talks to HWComposer.
A DisplayDevice doesn't have to have a HWComposer ID,
in that case it just can't use h/w composer composition.

- also replace C casts with C++ casts
- only the interface is changed, HWComposer still doesn't
fully handle multiple displays

This change refactors the FramebufferSurface class to inherit from the new
ConsumerBase class.

- 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.

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.

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 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.

we need to clear the whole framebuffer in that situation because
we can't trust the content of the FB when partial (fb preserving)
updates are used.

this happened when the overlays were in use, since the animation
is rendered in the FB and the FB is not used.
we now have a way to turn hwc off temporarily.

This is useful in various situations, for instance if the HAL
wants to change its compositing strategy.

Change-Id: I5afc14e5917c6db7926d7417d48677d5aba50caa
- we now clear the framebuffer upon request from the HAL
- the HAL list size could get out of sync with reality
- there was also an issue where sometime we could run past the list
