- don't call exit() if get_message() fails, simply terminate the thread and
  disable the T tracer
- T_dont_fork disappears, monitor_and_kill() as well, so now it's only 2
  processes: the main (enb/gnb/ue) and the local tracer

Removes phy_procedures_gNB_common_RX() (only used in nr_ulsim) + fixes
in pucchsim

This stops all ongoing threads (using pthread_join()), and marks FIFOs
to not block anymore. In this case, returned messages will be NULL.

A detached thread cannot be joined with pthread_join(). However, this
is crucial for correct resetting of the nr-softmodem. Therefore, do not
create threads in detached state.

- First stop threads then free memory
- Don't call kill_NR_RU_proc() twice (is called in stop_RU())
- Memory allocation optimizations
