rlcmac: Introduce lower primitive layer API
This primitive API allows the application to drive the RLCMAC layer based on a lower L1CTL interface.
* RACH req are requested to the lower layers by the RLCMAC through the RACH.req primitive. * Received ImmAss, SI are fed to the RLC/MAC layer through CCCH_DATA.ind * The RLCMAC registers DL and UL TBFs in the lower part (firwmare, L1CTL): ** The lower part will trigger PDCH_RTS.ind in every TS in the "(dl_slotmask|ul_slotmask)" superset, with the received USF. This allows UL uplink to transmit blocks when requested by USF, or UL/DL TBF to answer polls from PCU at a specific N+X FN (RRBP). This also allows the RLCMAC layer to update its GSM clock and trigger internall timeouts. ** The lower part will trigger PDCH_DATA.ind in every TS in the dl_slotmask if either a CTRL block is received or a data block matching the configured dl_tfi is received. ** Upon receival of PDCH_DATA.ind, the RLCMAC layer updates its FN clock and submits PDCH_DATA.req based on USF.
This commit only adds the primitive set and API to submit/receive them, but doesn't really implement them yet internally.
