3eb38cb33e SurfaceFlinger now uses the new VSYNC HAL API.
If h/w composer doesn't support vsync (version < 0.3) we
"fake" it with a timer.

478ae5eb5a Improve the VSYNC api a bit.
- 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.

23748668d3 fix a deadlock when removing a DisplayEventConnection
the deadlock would happen when the pipe became invalid and SF
trying to remove the connection from its list.

we know make sure to process events without holding a lock.

d0566bc26f Add support for sending VSYNC events to the framework
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.
