In this PR,
ALL_AT_ONCE(AAO) scheduling algorithm was added, which is reserved specifically for AAH sweep on device.Instead of constantly polling for ready angle sets like AAH, this implementation launch all angle sets at the same time. Receiving upstream data is guarded by waiting for request, whereas reflecting boundary dependency is guarded by latch.
Notable changes:
AAHD_ASynchronousCommunicator,AAHD_AngleSetandAAHDSweepChunk.AAHDSweepChunk::SweepintoAAHD_FLUDS.
