99ce5cdeb3 separate transactions from updates
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.

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.

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.
