Chris Forbes a3a09ef6b4 ui: Fix bad size check in Fence::unflatten
Differs slightly from mnc+ patch: GetFlattenedSize was fixed in mnc.

Test: Boot device, run poc from bug, observe no longer crashes

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.

Dan Stoza d318240042 libui: Enable -Weverything and -Werror
Enables -Weverything and -Werror, with just a few exceptions for
warnings we can't (or shouldn't need to) work around.

Colin Cross 288f2ef629 libui: fix passing Fence object over binder
The Fence object was writing a size_t into the binder buffer
in flatten, which changes size if the producer and consumer
are running in a 32-bit and a 64-bit process.  Use a uint32_t
instead.

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 ea74d3b78d make the warning timout of Fence::waitForever() implicit and longer
- timeout is now 3 seconds instead of 1
- simplifies the API a bit
- allows us to change/tweak this timeout globaly

Jamie Gennis 1df8c34585 libgui: disallow NULL Fence pointers
This change eliminates the uses of a NULL sp<Fence> indicating that no waiting
is required.  Instead we use a non-NULL but invalid Fence object for which the
wait methods will return immediately.

Jamie Gennis 82dbc7429f SurfaceFlinger: refactor frame time tracking
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.

Mathias Agopian b5c9dcdf3b Fence didn't manager sync_wait error codes properly
error codes are returned in errno, this caused ::waitForwever()
to only wait for 1 second and return improper error code (-1).

Jesse Hall ef19414bd8 Transfer HWC release fences to BufferQueue
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.
