- comment to GitLab merge-request does not anymore # as number (misinterpreted as issue number)
  - added local build script w/ generation of HTML result file
Improvements on bash scripts:
  - use of proper option parsing

We need to build the softmodem first, otherwise
compilation of the lib 'config' fails because
of the T tracer.

moved sidlink L1 functions to LTE_UE_TRANSPORT, corrected issue related to "find_dlsch" which is needed to compile UE and creates problem for unitary simulations (moved to lte-ue.c application)

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

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:

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 ...

This is taken from commit 7bc1434733421744ba1ea29316bec199d31c4399
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).
