Resolve "OAI-UE, DFT segmentation fault"

Closes #130

See merge request !42

Merge branch '130-oai-ue-dft-segmentation-fault' of https://gitlab.eurecom.fr/oai/openairinterface5g into 130-oai-ue-dft-segmentation-fault

2. Fixed a bug for HARQ rounds for TM1 frequency selective with PCE.

If your configuration file does not contain a parameter
the softmodem only printed "Failed to parse eNB configuration file"
without telling you what parameter was not found.

This quick fix adds a warning in such cases.

It also exists at the first error rather than trying to
parse the rest of the configuration file.

This hotfix does not change the processing at all.
At this point, stat_re == 0, so the behavior is the
same as before. But the code was wrong. There should
have been no test, it's a NACK, period.

Enhancement 16 tm rrc reconfig

This branch contains enhancements regarding signalling of the transmission mode
It also contains fixes for TM2, which now works with commercial phones
TM3 also works, but only with single layer
TM4 needs further improvements in uplink signalling (will be done in another branch)
All tests that pass for develop also pass for this branch (see https://gitlab.eurecom.fr/oai-internal/openairinterface5g/builds/560)

pdcch is now filled with dummy data (like it used to be) to enable better estimation of signal energy (also in unitary sims and oaisim)

Feature 44 dedicated drb



See merge request !33

oaisim parameter -y is now UE rx antennas
minor fixes to unitary sims

Merge branch 'develop' of https://gitlab.eurecom.fr/oai/openairinterface5g into feature-44-dedicated-drb
