Merge branch 'bugfix-48-L1L2signaling' of https://gitlab.eurecom.fr/oai/openairinterface5g into bugfix-48-L1L2signaling

added hotfix for DCCH bad size limitation (to be checked after merge with develop).  Changed UL idle scheduling to improve 5MHz performance, changed DCI aggregation for ue-specific DCIs (reduces contention with SI and RA in subframe 5 for 5 MHz). Added RRC timer for UE release which cleans L1.  Still issues in 10 MHz throughput with TCP. 5 MHz seems almost fine.
