1. Previous SW configuration for different RRC version relies on whether macro Rel10,
Rel14 defined or not by checking #ifdef Rel14 or #if defined(Rel10) || defined(R14).
Whenever there is a newer RRC version, e.g. Rel15, it will be very a tedious and
error-prone job to add defined(Rel15) in every place.
2. Some RRC messages are defined in release 13 instead of release 14, NB-IoT
feature is one of such example. Our code shall reflect this fact instead of using
an afterward version number in software configuration.
3. Some RRC messages or some fields of certain RRC messages are added in the middle
a release, e.g. SystemInformationBlockType1_v1310_IEs_t defined in RRC 13.1.0
and RRC 9.2.0 made some changes to SIB12 and SIB13 so we have sib12_v920 and
sib13_v920 fields in SIB12 and SIB13's struct.
We need a finer grain of control when using ASN1 from different RRC version.
4. S1AP also has this problem that it use UPDATE_RELEASE_9 and UPDATE_RELEASE_10 to
differentiate between various S1AP version.
This commit propose using MAKE_VERSION(x,y,z) to designate the version number and
modify current conditional compilation accordingly.

Summary of changes:
- some work on better parallel processing of eNB
try the eNB with options: --fepw --codingw
- small changes for multi-UE simulation and simulation accuracy
(UE power levels)
- initial work for the UE to use TUN device instead of ue_ip.ko
only done for oaisim, default bearer, compile with:
./build_oai --ue-nas-use-tun <rest of options>
- fix compilation of dlsim/ulsim/oaisim by defining some needed
global variables
- fix compilation of oaisim: compile coding and params_libconfig
- fix running of if4p5 with low CPU count (oaisim was not working
on the machine 'haswell' because of this)
This work is based on work by NTT.
To use the code, do:
./build_oai --oaisim --ue-nas-use-tun -t ETHERNET -c
This commit only handles oaisim in S1 mode.
We won't handle noS1 mode.
