Dan Stoza 5065a55291 libgui: Pass surface damage through BufferQueue
This change adds support for passing surface damage all of the way
down from the EGL interface through the consumer side of the
BufferQueue. Depends on system/core change

Dan Stoza 6fbefbbd8e libui: Clean up Fence and Region flattening
Fence was flattening incorrectly, causing issues with any fields
flattened after it, and Region was relying on being the last object
flattened. This change addresses both.

ywen aef0445c6f Fix a memory corruption issue when vector resize
There is memory corruption in below code

const Rect* prev = &dst[prevIndex];
dst.add(Rect(prev->right, top, right, bottom));

prev points to a memory of vector dst, when dst resize in add()
call, the memory that prev points to will be copy to the new
allocated vector memory and the old memory will become undefined

Avoid pointer in this case, use a local copy instead

Bernhard Rosenkraenzer fe4966d59b Restore Region::set(uint32_t, uint32_t)
The Region::set(uint32_t,uint32_t) ABI is used by the Nexus 10 graphics
driver blobs.
After commit dd883c0b08, Nexus 10 blobs
need a rebuild unless the old ABI is added back

Mathias Agopian e142428a9c Make Flattenable not virtual
Fallout from the Flattenable change, update all its uses.

Additionnaly, fix/tighten size checks when (un)flatten()ing
things.

Removed the assumption by some flattenables (e.g.: Fence)
that the size passed to them would be exact (it can
and will be larger in some cases)

The code in Parcel is a bit complicated so that we don't
have to expose the full implementation (and also to
keep the code smallish).

Mathias Agopian 2ca79399b9 latch transparent region hint only when we get a new frame
since the transparent region hint really depends on the
content of the window containing the SurfaceView
(it's calculated by the view hierarchy based on
overlapping views), it makes sense to latch it only when
the content of the window (the app) changes.

This should help fixing drawing artifacts when changing the
layout of a window containing a SurfaceView.

Chris Craik 3e010f3138 Add createTJunctionFreeRegion
T-junction free regions are useful for rendering regions with various
geometric transformations, and the Region's span-ordered, sorted rect
list supports T-junction free storage without modification.

This approach creates a T-junction free region by splitting each
rectangle that is part of a vertical T-junction. This approach is two
pass (up and down) so that divisions can trickle up/down to other
adjacent spans.

Mathias Agopian 3ab68558fa change how we store Region data internally
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).

Mathias Agopian 4c0a170585 don't generate a new Region when translating by 0,0
since regions are copy-on-write, this prevents to
duplicate the region entirely and offseting by 0,0 is
fairly common.

Mathias Agopian 8683fca395 improve [un]marshalling of non-binder objects
this change introduces a new class LightFlattenable<> which is
a protocol to flatten simple objects that don't require
binders or file descriptors; the benefit of this protocol is that
it doesn't require the objects to have a virtual table and give us
a consitant way of doing this.

we also introduce an implementation of this protocol for
POD structures, LightFlattenablePod<>.

Parcel has been update to handle this protocol automatically.

Sensor, Rect, Point and Region now use this new protocol.

- it returned an empty rect when the region was empty, instead
of returning an empty list of rect.

- also fixed an infinite loop when boolean_operation was given
an empty list of rects

Mathias Agopian d0b55c011a fix [4093196] Device lock up - log spam with SharedBufferStack: waitForCondition(LockCondition) timed out
a memory corruption happned when the buffer pool was resized
(like when playing a video or using camera) and there was
no current active buffer. In this case, the faulty code
would index into an array at position -1 which corrupted
24 bytes of data.

also improved region validation code (ifdef'ed out by default)

Romain Guy b801624dc4 Optimize FBO drawing with regions.
This optimization is currently disabled until Launcher is
modified to take advantage of it. The optimization can be
enabled by turning on RENDER_LAYERS_AS_REGIONS in the
OpenGLRenderer.h file.

Mathias Agopian 0926f50664 update surfaceflinger, libui and libagl to the new gralloc api
- Currently the lock/unlock path is naive and is done for each drawing operation (glDrawElements and glDrawArrays). this should be improved eventually.
- factor all the lock/unlock code in SurfaceBuffer.
- fixed "showupdate" so it works even when we don't have preserving eglSwapBuffers().
- improved the situation with the dirty-region and fixed a problem that caused GL apps to not update.
- make use of LightRefBase() where needed, instead of duplicating its implementation
- add LightRefBase::getStrongCount()
- renamed EGLNativeWindowSurface.cpp to FramebufferNativeWindow.cpp

- disabled copybits test, since it clashes with the new gralloc api

- Camera/Video will be fixed later when we rework the overlay apis
