This is a squash merge of commits introducing the new split Upper Link Layer and Lower Link Layer architecture of the Bluetooth Low Energy controller. This introduces a new, improved Link Layer based on the concept of split responsibilities; The Upper Link Layer (ULL) is in charge of control procedures, inter-event scheduling and overall role management. The code for the ULL is shared among all hardware implementations. The Lower Link Layer (LLL) is responsible for the intra-event scheduling and vendor specific radio hardware access. The communication between ULL and LLL is achieved through a set of FIFOs that contain both control and data packets.
