Fronthaul xran library F release support

Browse Source 
Major improvements:
  1) bbu_offload - enable packet handling on BBU cores
  2) dlCpProcBurst - DL CP processing on one or more symbols
  3) SRS CP processing - depends on the RU capabilities that can be
    retreived via M-plane (if RU is CAT B)
  4) nSecDesc - the number of section descriptors per symbol; it was hardcoded to 0 in E release;
    depends on the RU capabilities that can be retreived via M-plane
  5) RunSlotPrbMapBySymbolEnable - enable PRB mapping by symbol with multisection;
    depends on the RU capabilities that can be retreived via M-plane
  6) DSS (Dynamic Spectrum Sharing) support - depends on the RU capabilities that can be retreived via M-plane

Minor fixes in F that exist in E:
  1) prach_config->nPrachFilterIdx - explained in commit ID f3045396
  2) T1a_min_cp_dl - explained in the commit under title "Clarification on DU delay profile"
  3) fh_config->nULRBs - explained in commit under title "Further clarification on xran E release parameters"

Removed const for prb_conf argument in oran_allocate_cplane_buffers()
function, as F release requires the not const struct for
xran_init_PrbMap_by_symbol_from_cfg() and xran_init_PrbMap_from_cfg()
even though the struct is not modified inside of these functions.
