When we run with the RT scheduler and the address sanitizer in Ubuntu
18.04, pthread_create will hang and never create threads.  This adds
some explanatory text in CMakeLists.txt to explain about this issue.

MR !1490 add support for 15 kHz SCS
MR !1525 Make USRP tune-offset configurable
MR !1550 remove UEid in MAC

To SIB2 and its passing to RRC. Parameter was read but not transfered
before. Basic LTE-M functionality should ok on develop branch with this
fix. Tested with uBlox SARA-R4 (QCOM chipset)

After this commit, only the RNTI is used as an identifier in the MAC.
Further, it removes some module_id, but a lot of them remain (the goal
to remove all is still far from us)
