UE_list_t is now used as a separate list. It can be e.g. used in the
scheduler to mark groups of users. The original UE_list_t is renamed to
UE_info_t to reflect that it is a container for information about UEs.

ENABLE_ITTI macro removal, modified telnet server to support all executables, modified record player to finalize switch to run-time option and allow usage with any device

remove RRC_VERSION macros, simplify build-oai and CMakefile.txt accordingly, get rid of remaining compilation warnings (opt module improperly merged and patch asn1c files with tests against max 64 bits integer value)

Functionalities Added:
	- Modify RAR message to use number of repetitions configuration added in last commit
	- Configure msg3 with number of repetitions
	- DCI configuration for repetitions
	- Repeat MAC UL config each SF for the number of repetitions
	- PHY combining of repeated SF

phy_simulators do compile, but dlsim&nr_(ulsch/dlsch/pbch)sims do not pass tests + Raphael's CI patch applied.

For whatever reason most of the files had their permission
changed from 644 to 755, which is not wanted.

Remove a change about MSG2 and MSG4 because this is used not only in L2 FAPI simulator but also in real eNB.

Change not to watch timing in MSG2 and MSG4 procedure in L2 FAPI simulator because it's possible to differ timing(frame, subframe) between eNB and UE.
