Fix the problem that duplicate type names exist in OPEN TYPE.

The following excerpt of ASN.1 of X2AP is one example.

  HandoverRequestAcknowledge-IEs X2AP-PROTOCOL-IES ::= {
    { ID id-Old-eNB-UE-X2AP-ID  CRITICALITY ignore  TYPE UE-X2AP-ID  PRESENCE mandatory}|
    { ID id-New-eNB-UE-X2AP-ID  CRITICALITY ignore  TYPE UE-X2AP-ID  PRESENCE mandatory}|
    ...
  }

this is the one that also works with the n310

1. Fix the problem of compiling NR_RangeToBestCell.c of NR-RRC 15.3.0
2. Fix the problem that default OCTET/BIT STRING value not used in APER
3. Add support of extension group inside CHOICE type used in LTE-RRC 15.3.0
4. Fix the problem that NGAP 15.0.0 ASN.1 can not generate C files

- install package 'vim-common' to have 'xxd' needed by the compilation
  process of the T tracer
- change the way xxd is called so that no file is created in case
  of error

- use OAI location to retrieve asn1c
- use a specific commit instead of a branch name

This was used for the ITTI analyzer.

The ITTI analyzer is now to be considered obsolete.
The source code will be removed at some point.

Add `autoreconf -iv` in build_helper to create configure file for asn1c.

1. It's no need to modify LTE-RRC's ASN.1 file for enabling option group
   feature in generate_asn1.
2. It's no need to patch the C header files generated from
   LTE-RRC/S1AP/X2AP's ASN.1 in fix_asn1.
3. It's no need to pre-process S1AP/X2AP's ASN.1 for enabling information
   object class feature by asn1tostruct.py.

This commit requires an un-official version of asn1c which are
collaboration of asn1c community members and `build_helper` is modified
in this commit accordingly :

  https://github.com/brchiu/asn1c/tree/velichkov_s1ap_plus_option_group

This asn1c can also convert ASN.1 of 5G NR RRC (38.331, v15.1.0) and
generate C files with -findirect-choice command line option without
tweaking ASN.1 file.

Examples for how to use this asn1c for S1AP are in S1AP files, e.g.
s1ap_eNB_nas_procedures.c and s1ap_eNB_handler.c.

There is an modified openair-cn (based on tag 0.5.0) with this new asn1c at :

  https://github.com/brchiu/openair-cn/tree/new-asn1c

Basic S1AP interaction and data transfer operation between OAI eNB and
this modified openair-cn has been tested.

Note: Community version of asn1c is keeping evolved to provide better usage.

  -- Stability issues when installing packages for USRP variants on new VM
     It sometimes timed-out
     Added loop up to 5 tries to add apt-repository
  -- Temporary merge during MergeRequest processing now returns an
     error when there are any conflicts
     Will stop the whole build
  -- Physical simulator now has a XLST for the XML result

The following was not working properly:

    ./build_oai -I -w USRP

After this commit it works.

And so does:

  ./build_oai --eNB -w USRP

It has been chosen to not include the full history of commits
from David. He included a binary version of wireshark, probably
a modified one that understands NFAPI. Wireshark is released under
the GPL license, we cannot include it in the repository. We could
have done a next commit to remove this binary. But then it would
still be present in the history of commits, which may not be allowed.
And it would take space on disk. We could edit the history to remove
wireshark entirely. But this operation is too complicated.

There was also a pcap capture file, which has nothing to do in
the history of commits and would take space on disk. There again,
it's too difficult to edit the history to remove it.

There was a file .gitignore that was also removed.

The original history can be found on David's repository:
https://gitlab.eurecom.fr/daveprice/openairinterface5g/
The branch is: nfapi-ru-rau-split.

A copy of that branch has been included in the internal OAI
repository, for those who have access to it.
The branch is the same. The last commit ID is
9106438239e0bc626ff1fa1d97d911caadd0fbb9.

You can compare the current commit with the commit 9106...
to see what differs.

The current commit has to be considered non-working.
The commit following the current commit will fix problems with
the work in the current commit.

If you use git bisect, don't spend time analyzing the current
commit.

Basically, build_helper has been adapted so that:
  ./buil_oai -I -w USRP
works for Ubuntu 17.04 and 17.10.

Concerning those systems:
- compilation with "--eNB --UE -w USRP" works
- the enb softmodem runs on 17.04 (not tested on 17.10)
- nothing else has been tested.

Users should report any problem.

These steps take time and are not necessary.

protobuf-c does not compile anymore.

Let's handle this a bit better.

We now install protobuf and protobuf-c only for the
flexran agent. That is, if you want to use the flexran
agent, you need to install protobuf/protobuf-c and
you do it this way:

  ./build_oai -I -a

(you add -a)

Other targets don't need protobuf nor protobuf-c, so
it's not installed by the -I command of build_oai,
unless you pass -a with -I.

Also, we now use protobuf 3.3.0, not 2.6.1. The code
has been adapted, a quick test seems to indicate that
the system works, but it has not been intensively tested.

Discovered and fix problems in shared lib build for usrp,bladerf and lime

Let the user see how many warnings a compilation generates.
The goal is to have 0 warning, for any compiled component
of openair.

- build script has ability to indicate location for downloading uhd images
- one simple wrapper to set environment variables and initiate another program (supposed to be lte-softmodem)
