When a header is changed, all including files need to be recompiled,
too. Thus, including a header needlessly all over the place drives
compile times up without any reason.

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)

  -- cell synchronization was successful on the 1st try (in OAI UE + USRP) test

Remove deprecated build options, now available as config options: noS1, basic_simulator. Remove DISABLE_LOG_X macros, disabling logs now available via disabling the T_TRACER

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

In case of oaisim, dl_phy_sync_success has to be called
by initial_sync, as it used to be.

We introduce an #if OAISIM, this is not elegant, but will
do it for the moment.

Note: this commit is work in progress. Contains initial integration of NFAPI data structures which are tested for TX path. RX path to follow.

- rename UE_NO_LOG to DISABLE_LOG_X
  because the name is misleading. The full software
  is impacted, not only the UE part
- same for compilation option ---ue-no-log
  that becomes --disable-log
- keep LOG_X for the standard case, that is the
  case without DISABLE_LOG_X where printf has been
  put. Two reasons:
  * printf is not realtime friendly
  * keep behavior similar for other users who may
    be troubled by different logs that don't add
    any benefit to previous logs

for DCI format 2. Temporaryly going back to the previous
version of code.
2. Enabling rate adaptation with multiple HARQ rounds.
(no change inside the rounds).
