Change in libosmo-gprs[master]: rlcmac: Introduce lower primitive layer API

Attention is currently required from: pespin, fixeria. Hello Jenkins Builder, laforge, fixeria, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmo-gprs/+/31177 to look at the new patch set (#4). Change subject: rlcmac: Introduce lower primitive layer API ...................................................................... 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.
