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.

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.

- don't advertise extensions that are not supported
by any implementation
- remove EGL_ANDROID_swap_rectangle which is not
implemented by anybody and confuses people
- add some comments about mandatory extensions

this would happen when toggling on/off/on very fast, the screen
could stay black (while the panel is on).

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.

- renderscript now calls EGL directly instead of relying on this function
- surfaceflinger also does its own EGLConfig selection
- selectConfigForPixelFormat stays for legacy reason (many tests use it) but
it now only tries to match the alpha channel of the format rather than the
format itself.
this will allow implementations who don't support the exact formats
defined in the HAL to work properly.

There are 16 events logged in the event log:
SF_APP_DEQUEUE_BEFORE
SF_APP_DEQUEUE_AFTER
SF_APP_LOCK_BEFORE
SF_APP_LOCK_AFTER
SF_APP_QUEUE
SF_REPAINT
SF_COMPOSITION_COMPLETE
SF_UNLOCK_CLIENTS
SF_SWAP_BUFFERS
SF_REPAINT_DONE
SF_FB_POST_BEFORE
SF_FB_POST_AFTER
SF_FB_DEQUEUE_BEFORE
SF_FB_DEQUEUE_AFTER
SF_FB_LOCK_BEFORE
SF_FB_LOCK_AFTER
all events log the buffer conserned and a timestamp in microseconds.
by default the logging is not enabled, to turn it on:
adb shell service call SurfaceFlinger 1006 i31 1
adb shell setprop debug.graphic_log 1
The effect is immediate in SurfaceFlinger, but applications need to be
restarted.

- 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

moved surfaceflinger, audioflinger, cameraservice
all native services should now reside in this location.
