RACH received on VNF.  Message 2 created and sent to PNF.  Got Message 2 received on PNF.  Nothing useful done with it yet

Merge from RU-RAU-split and fix of frame/subframe handling.  Was very confused with the counter in the main loop, the incrementing from the USRP read library and the nFAPI frame handling.  RACH seen on wireshark and something happens on VNF

handling of PDCCH order. stoping UE-specific scheduler during RA procedure. checking for DCI format (resource allocation) to not overwrite resource_block_coding for format 1A DCIs.

put 50 PRB back in default enb configuration. added handling of UE release in L1/L2. detection of stale ULSCH configuration

removal of LOG_I put for debugging.

internal use, no documentation, no support.

we can't use &ul_config_pdu->ulsch_harq_pdu.harq_information directly,
because that function is called for 2 cases and the substructure
harq_information is not as the same position in both cases.

Merge from official RU-RAU-split branch.  Tested with san jole and UE - network is seen.  Not tried RACH

switching some LOG_I to LOG_D, fixes for RRU IF4p5. It was broken after changes in configuration procedures. Some configuration file changes.

NFAPI RACH now working.  Gets sent to VNF.  VNF cores currently on receipt.  Probably fixed by merge from main RU-RAU-split which I will do next

- don't use o_flip anymore in ulsch_decoding
- remove dl_cqi from eNB_UE_STATS
- put dl_cqi[NFAPI_CC_MAX] in UE_sched_ctrl
- adapt code for this dl_cqi change (from eNB_UE_STATS to UE_sched_ctrl)
- extract_pusch_csi has been fixed for CQI_ReportModeAperiodic_rm30,
  the others need to be done. Program will exit if one uses them.
  Not sure if setting sched_ctl->dl_cqi[CC_idP]  has to be done in this
  function...

Over write Raymond's copy of the open nfapi diff with the one that I am using - it re-orders the processing of dl_config and tx_req

Network search working again.  Now calling generate_dci_top every subframe, using dummy subframe if no data to transmit. MIB and SIB2/3 coming out.  UE sees cell
