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

- 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...

- remove old unused code
- check dlsch0 the right way

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

fixed various bugs in NFAPI interface and DCI CCE allocations (eNB_scheduler_primitives.c:allocate_CCEs())

fixed coherency issue across slots for PUCCH 1A/B detection (energy detection component). Introduced a variable scaling for channel matched filter in PUCCH1A/B detector. Current version goes as far on simulator as RU-RAU-split prior to merge with develop
