This work was done by Laurent Thomas.

This reverts commit d31634c3.

Laurent Thomas had a problem on one machine with the build_oai
way of checking for nettle.

The problem with the alternative solution of including nettle/bignum.h
is that it is very unclear.

The problem with nettle is that the file nettle/config.h does not
exist for version 2. It was introduced in version 3.

We want to support both versions, but there is an API incompatibility.
So we need an #if #else mechanism.

The file nettle/bignum.h is present in both versions 2 and 3 and it
includes nettle/version.h in the version 3.

So by including this file, we can check for the existence of
NETTLE_VERSION_MAJOR (that comes from nettle/config.h) in the
code.

But as you can see, the reasoning is way too complex.

So it's better to keep the check in cmake_targets/CMakeLists.txt.

As long as we support version 2 this will be the way to go.

It is possible to force a given version in specific non-generic
customized environments.

when testing on haswell, using apt-get to install LimeSDR
libraries and includes, it put it in /usr/include, not
/usr/local/include

As reported on the mailing list, there was a problem
for some users. The link phase of building the simulators
was giving the error "undefined reference to ATL_scopy".

Another way to set those two variables has to be used for the
specific UE case (use a sub CMakeLists.txt, see in build_oai).

debugging information in lte-enb, addition of external reference option in lte-softmodem and usrp_lib.cpp

- add progess bar report
- reduce ssh max_tries to 10
- cleanOldPrograms -> change kill cmd line to be able to run autotest on same machine than lte-softmodem (thanks Rohit & Gabriel)
- Cleanning output prints
- add --skip-machine-preparation on cmd line
- add --skip-sanity-check on cmd line
- add HTML REPORT (no-S1 only)
- add XML detailled report (no-S1 only)
