-- in python: detection of a build failure, the tab should close nicely
  -- L2-nFAPi simulator: adding the num-ue-thread option
  -- Moved the VM destroy stage into the "VM-based test" branch.
  -- On "slave" job pipeline, moved the XML parsing after the git merge step so new test-cases are nicely taken care of.

* Instead of partly initializing in read_config_and_init(), everything of
  PDCP is initialized in main() of lte-softmodem
* Omit RC.rrc access in RRU through checking of RC.nb_inst > 0
* Includes FlexRAN, i.e. do not start FlexRAN in RRU
* Function pointers to PDCP functions have to be set explicitly (avoid
  confusion of multiply setting function pointers)
