Fixed the issue with synchronization but only for the case o running both eNB (vnf) and UE (pnf) processes in the same machine. Receiving and decoding now all MIBs and SIBs1/2/3.

Testing works up to the reception of SIB1/2/3 from the UE through nfapi, but there is an issue with missing some of the nfapi messages for some frames.

Testing works until the call of callback function pnf_p7_subframe_ind. There, it never satisfies the condition if(tx_subframe_buffer->sfn_sf == sfn_sf_tx) so both sides (vnf and pnf are hanging).

Introduce nfapi_mode variable to differentiate functionality between phy_stub_ue mode (nfapi_mode=3) and normal full stack mode (nfapi_mode!=3).

Crashes around msg4 time, but understand that need to get the ACK for the UE UL of msg3 back to UE within 4ms

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

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

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

remove getopt call in configuration module, it changes the argv order. Fix configuration module bugs (command line arguments sometimes not properly processed

Improve configuration module error management at init time, Fix command line help option processing, remove shotopt field from parameter structure

lte-softmodem -O <config file> will trigger legacy config mode
ltesoftmodem  -O libconfig:<config file> will trigger configuration module usage.

added configuration file for nFAPI PNF (oaiL1) and modifications in startup procedure to initialize L1 only. When executed, it just waits for configuration, which will never come ... Provides and initial framework to integrate NFAPI PNF modules.

addition of MPDCCH format 5. X_u_br sequences for BL/CE UE support and bugfixes in rx_prach0 for eMTC.

fixes for RRU/RAU function after changes for monolithic eNB (some things during init were broken for RRU)

Note: this commit is work in progress. Contains initial integration of NFAPI data structures which are tested for TX path. RX path to follow.

Optimisation of rx_pdcch : save some time by reading one symbol pdcch first and read symbol 2 and 3 if needed
Optimisation of nb of candidate when searching DCI
