agl-service-unicens: Rx message event
Bug-AGL: SPEC-1177 Implements /subscriberx function. Control Rx messages will be notified to subscribers. If no subscriber is assigned, then Rx messages are discarded. This avoids Rx stuck issues after receiving multiple messages. Change-Id: Idb71569b8ff6f651833d7d01c37a3eea866daf1d Signed-off-by: Tobias Jahnke <tobias.jahnke@microchip.com>
