2017-08-04hwc2: Wait for RegisterCallback() from SF before sending events.Ramkumar Radhakrishnan
Surfaceflinger registers callback functions to be called from hwcomposer on specific events like hotplug, vsync and screen refresh. since surfaceflinger and hwcomposer are two different processes that can run asynchronously. This causes hwcomposer to send an event to surfaceflinger before surfaceflinger registers callback and results in undefined behavior. So wait for callbacks to get registered by surfaceflinger and send an event to surfacelinger. Change-Id: I288e4d7dde8179cb4a119cdedad2877344c06dae CRs-Fixed: 2085392
