SF could end-up in an infinite crash-loop during startup if it
was stopped while the screen was off. This happened because
the thread that manages screen blanking was started before
other important pieces of SF were initialized.

we're seeing UI freezes when window updates and
composition are separated. for now we workaround this
by always doing a composition after window updates on
vsync. triple buffering is reenabled for performance.

In some situations SF would mark a window as "has a pending update"
but would never process that update because the window is not
visible (fully transparent, hidden by another window, etc...), this
window would then be "stuck" until some other window updated.

recent changes in SF introduced a hang where some windows would
stop being refreshed.
This is an attemp to fix that.

with this changes, SF transactions are handled as soon as possible
but do not trigger updates. the update is delayed until the next
vsync.
this allows us to work much better without requiring triple-buffering.

--latency-clear [name]
clears the latency data for the specified layer or for
all layers if none is specified
--list
prints the list of all layers regardless of their visibility

It is now possible to say:
dumpsys SurfaceFlinger --latency
to print latency information about all windows
dumpsys SurfaceFlinger --latency window-name
to print the latency stats of the specified window
for instance: dumpsys SurfaceFlinger --latency SurfaceView
The data consists of one line containing global stats, followed by
128 lines of tab separated timestamps in nanosecond.
The first line currently contains the refresh period in nanosecond.
Each 128 following line contains 3 timestamps, of respectively
the app draw time, the vsync timestamp just prior the call to set and
the timestamp of the call to set.

Several source files privately defined macros LIKELY and UNLIKELY in terms
of __builtin_expect. But <cutils/compiler.h> already has CC_LIKELY and
CC_UNLIKELY which are intended for this purpose. So rename the private
uses to use the standard names.
In addition, AudioFlinger was relying on the macro expanding to extra ( ).

- add the ability to set the vsync delivery rate, when the rate is
set to N>1 (ie: receive every N vsync), SF process' is woken up for
all of vsync, but clients only see the every N events.
- add the concept of one-shot vsync events, with a call-back
to request the next one. currently the call-back is a binder IPC.

Layer::lockPageFlip() and layer::onRemove() could be called on
different threads and race such that lockPageFlip() successfully
called mSurfaceTexture->updateTexImage() but then gets NULL back from
mSurfaceTexture->getCurrentBuffer(), leading to a crash.
This change moves Layer::onRemove() calls to
SurfaceFlinger::commitTransaction() so they happen after the Layer is
done being drawn from and only happen on the main surfaceflinger
thread.

use gui/DisplayEvent to receive the events. Events are
dispatched through a unix pipe, so the API is compatible
with utils/Looper. see gui/DisplayEvent.h for more info.

Note: the system would recover after a 5 second timeout.

The ScreenShot layer is now created hidden. The screenshot itself
is aquired during the transaction when the layer is made visible.
This guarantees the screenshot and the layer happen atomically
with respect to screen updates.

We now have mInvalidateRegion which holds the region to invalidate, it
can be set from any thread as long as mInvalidateLock is held. We use
fine-grained locking here because mInvalidateRegion can be set from anywhere,
in particular frmo HWC callbacks.

A LayerScreenshot is a special type of layer that contains a screenshot of
the screen acquired when its created. It works just like LayerDim.
Make sure to call compositionComplete() after rendering into a FBO.

there was situations where SF's main loop would run (as if there was
an invalidate), but the dirty region was empty (so no new buffers
were retired). In this case we return early and don't swap, which
would cause drawing artifacts.

when taking a screenshot, in particular, we could end up
with stale GL state when drawing LayerDim which resulted
in incortect rendering.

removed a test that could violate this guarantee. note that we
have no proof tha this ever happened, but consequences could be
hard lock-ups.
the code here was intended to track the region to update for displays
that can do partial update. the logic discarded the update entirely
if that region was empty. instead we just redraw the whole thing
(note that we should never be there with an empty region and retired
buffers though).
