Summary of changes:
- split UE and eNB directories
- nFAPI L2 emulator
- basic simulator
- various bug fixes

The nFAPI L2 emulator is not functional yet. Some code had to be removed
because it made the monolithic eNB non functional.

The unitary simulators (ulsim, dlsim) do not compile anymore. This will
be fixed later.

Remove warnings found while running:
    ./build_oai --UE -c -w USRP

And:
    ./build_oai --basic-simulator -c

Remove warnings popping up on:
    ./build_oai --eNB -w USRP

Maybe not always the best solution.

MAX_MOBILES_PER_ENB cannot be used to compile ue_ip
because it is defined in platform_constants.h and this
cannot be included to compile a kernel module.

Let's use NUMBER_OF_UE_MAX as it was before instead.

The new 'basic simulator' is now functional.
A proper solution is needed to deal with SIB18/19/21
for the D2D functionality.

This is a quick and dirty solution, something better is needed.

- conf2uedata compilation was not properly started
- success/failure of compilation of UE and eNB
  was not handled properly

Conflicts:
	openair1/PHY/LTE_TRANSPORT/prach.c
	targets/RT/USER/lte-ue.c

Conflicts:
	openair1/PHY/defs_eNB.h

Status so far:
- monolithic eNB compiles and is functional with 1 UE in FDD, 5/10/20MHz.
  For 20MHz we don't have a nice TCP downlink (on haswell).
- oaisim does not compile
- UE does not compile
- phy simulators don't compile
- many new warnings

One user had a problem compiling oaisim.
This commit fixes it.

The compilation log was saying:

    targets/RT/USER/lte-ue.c:
    In function UE_thread_rxn_txnp4:

    openair2/UTIL/LOG/log.h:370:3:

Merge remote-tracking branch 'origin/nfapi-L2-emulator-for-develop' into develop_integration_2018_w19

It was not possible to merge the branch directly, because the
history of this branch contains files that cannot be in the
repository, namely wireshark from Cisco work on nFAPI.

As for Cisco work on nFAPI, a special commit containing all the
work is thus created.

Below is the output of the command:
git log --graph 184d51c6..61276d87

184d51c6 is the commit ID of the develop
branch prior to the merge.

61276d87 is the commit ID of the
nfapi-L2-emulator branch prior to the merge.

The commit 61276d87 (and all its
history) will be removed from the main OAI repository. It is
present in the internal OAI repository for those who have access
to it.

There was also some cleanup done on the code.

Some changes were necessary to have the eNB functional. They may have an
impact on the FAPI L2 simulator, which may be non-functional and requires
some work to be functional (and not break other use cases).

The most critical ones are:
- in openair2/RRC/LITE/MESSAGES/asn1_msg.c, in the function do_SIB23:
  SIB 18/18/21 are not included because they make the MAC message to
  big for the SIB scheduler
- in targets/RT/USER/lte-enb.c, in the function eNB_thread_rxtx,
  the following code has not been included because it breaks the
  regular eNB:
     //Panos: NEW ACHECK FOR VNF HERE!
     //if(nfapi_mode!=2){
     if(get_nprocs() >= 8)      wakeup_tx(eNB,eNB->proc.ru_proc);
     else if(get_nprocs() > 4)
     {
       LOG_I(PHY, "Panos-D: In eNB_thread_rxtx() before re-calling phy_procedures_eNB_TX() and wakeup_txfh() \n");
       phy_procedures_eNB_TX(eNB, proc, no_relay, NULL, 1);
       wakeup_txfh(proc,eNB->proc.ru_proc);
     }

It is possible to see the differences between this commit and the commit
61276d87 to get all the differences between
the two. Use: git diff 61276d87 <this commit>

Here is now the output of "git log [...]".

      Definition of the UE MAC interface: IF_Module_UE.h, IF_Module_UE.c, UE_MAC_interface.h and the supporting functions.
------------------------------------------------------------------------------

This is taken from commit 7bc14347
and is necessary for the UE to function properly.

Whenever the value T_BUFFER_MAX changes, the tracers had to
be recompiled. The only reason why it was needed is because we
used some fixed size buffers to read events. This commit removes
this restriction.

Also, with the basic simulator, this value T_BUFFER_MAX now comes
with an #ifdef which would have required some special hackish-level
tricks in the tracers, which is not good.

Let's just allocate memory when needed.

This commit introduces a 'basic simulator'.

This basic simulator is made of:
- the standard eNB code using a special driver that mimics the USRP driver
- the standard UE code using a special driver that mimics the USRP driver
- no channel simulation
- some special code to deal with faster-than-realtime behaviour of this
  basic simulator

It connects one UE to one eNB. It requires an EPC, populated with the
correct configuration for the UE.

This is the initial release and may contain bugs (most probably race
conditions due to the faster-than-realtime behaviour).

To use it, see the documentation at:
    targets/ARCH/tcp_bridge/README.tcp_bridge_oai.

It has been tested with 25, 50 and 100 RBs, FDD mode.
(No check at all has been done to know if it could work in TDD mode.)

That allows to run several programs using this mechanism on the
same computer (say both eNB and UE, to debug).

UE directory splits, creation of UE-specific files, common UE/eNB files and extraction of UE/common components from eNodeB files. renaming of files to minimize common names across directories (i.e. defs.h, vars.h, extern.h)

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.

Note: 2018/04/16, Modified based on Cedric's comment.

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>
