bugfixing for UL. Remaining problems: CCE allocations in subframe 5 lead to occasional illegal DCI allocations (affects UL DCI which is missed by UE). waveform compliance with CQI in ULSCH.

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.

it was at the wrong place
it was also wrong (< instead of <=)

added Timing advance tracing to .vcd output. Increase maximum UL RB count to 45. Measured UL throughput @ 15 Mbit/s (40 PRBs).

changes in BSR handling in eNodeB. UL throughput on 5 MHz is 8 Mbit/s (mcs 19, 20 PRB). MCS 20 is not working for an unknown reason.

in openair2/ENB_APP/enb_config.c
it was tested against 63, it should be tested against 15
no impact on processing whatsoever so no need to test

Make it compile on 15.10 (problem with gcc-xml not resolved, may be do as in openair-cn: disable it, it is only needed for ITTI ANALYZER)

increase maximum users in eNodeB to 16
