10125f00a5 Fix deadlock in SF.
problem was that we were acquiring a strong reference
on Connection object with a lock held, when those
got out of scope (lock still held) their dtor
could be called if all other refs had dropped,
the dtor would acquire the lock again to
remove the Connection from the main list. boom.

we rearange the code so this doesn't happen.

8630320433 split HWComposer out of DisplayHardware
we will only ever have a single instance of HWComposer, so
it's now an attribute of SurfaceFlinger, instead of being part
of DisplayHardware.

DisplayHardware now just represents a "display" (it should be renamed).

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.
