In testing, I observed one instance of a call failing due to a signal
sent to the process. This could happen at various times so it's better
to be safe than sorry.

Wait for the early suspend transition to finish to the point where
surfaceflinger would previously have synchronized. This is important
during screen on, to ensure the display early suspend handlers have
completed before surfaceflinger unblanks.

SurfaceFlinger and PowerManagerService manage their synchronization
without the help of early suspend, and SurfaceFlinger no longer unblocks
early suspend. Add a new thread when early suspend is detected that will
immediately unblock early suspend.

libsuspend provides functions autosuspend_enable() and
autosuspend_disable() to trigger suspend on a variety of different
kernels.
