If available, surfaceflinger will use the hwc setCursorPositionAsync()
api to change the position of supported cursor layers outside of
the usual prepare/set loop.

The gralloc API now provides a way for using lock/unlock with the Android
explicit synchronisation concept. This changes updates the GraphicBuffer class
to also expose this functionality, and updates the Surface class to make use of
in line with the dequeueBuffer/queueBuffer mechanism.
This new behaviour is dependent on GRALLOC_MODULE_API_VERSION_0_3. If the local
gralloc module does not support this then the existing synchronous lock/unlock
mechanism will be used.

Add SRGBTest.RenderToSRGBSurface, which validates that passing the

results in an SRGB surface by comparing the output values to those
of a standard RGB surface.

- this implements vec2, vec3, vec4, which are float vectors
of size 2, 3 and 4 respectively.
the code allows easy instantiation of vectors of a different
type via the tvec{2|3|4}<T> template classes.
- this also implements mat4 which is a float 4x4 matrix. the
tmat44<T> template class allows easy instantiation of a
4x4 matrix of a different value_type.
The vector types have some minimal support for the
glsl style swizzled access; for instance:
vec4 u;
vec3 v = u.xyz;
only .x, .xy, .xyz and their .stpq / .rgba equivalent are
supported.
most operators are supported on both vector and matrices:
arithmetic, unary, compound assignment and comparison
(bit-wise operators NOT supported).
- operations available on vectors include:
dot, length, distance, normalize and cross
- operations available on matrices include:
transpose, inverse, trace
- and a few utilities to create matrices:
ortho, frustum, lookAt

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).

until now it was only used to discard a layer entirely.
we're now reducing the size of the layer if it is still
visible, if possible.
this works for instance when a surfaceView is used and
only the menu bar is displayed over it.

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.

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.

This change moves the frame time history tracking code out of Layer and into a
new class called FrameTracker. It also changes the tracking to use signal
timestamps from fences when available for more accurate results.

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).

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.

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.
