term_nr_ue_signal() frees all memory, except for dfts lib load

Frees all allocated memory, except for library loading related, and ul
reference signal sequences, which are allocated in static variables

- introduce loader_reset() that frees all memory
- resolve memory leak in loader_format_shlibpath()
- correctly handle library reload: check if a function has been
  retrieved already. Don't leak memory (strdup()), and handle multiple
  reloads of different functions from the same SO

- install libasan in physim containers
- run physim containers with SYS_CAP_PTRACE capability
- remove static-libasan: not available in RHEL8:

  The physims are tested in a container environment on top of RHEL8. To
  my knowledge, no package provides the static ASan library there.
  Therefore, remove it here to be able to run these tests.

This merges the following MRs:
- MR !1436 fairRR LTE scheduler fixes: should make the connection more stable, less UL retransmissions
- MR !1386 phy sync improvements: the 5G NR UE should sync better
- MR !1361 FDD support (no traffic): adds FDD support for the scheduler, but heavy traffic has not been tested
- MR !1447 using uid for PUCCH RRC conf: use the RRC UID to decide on PUCCH resources, should in particular avoid the "PUCCH straddles DC carrier" assert
- fix for 5G F1 RFsim test fail

Merge branch 'NR_2port_CSIRS' of https://gitlab.eurecom.fr/oai/openairinterface5g into NR_2port_CSIRS

Overwriting sched_pusch information at that stage would in particular
lose information on the current frame/slot. Overwriting sched_pusch with
the retInfo structure is already done at the end of
allocate_ul_retransmission(), and is therefore not necessary at this
stage.

We compute the preferred DL TDAs when receiving the cellGroup from the
RRC. However, in F1 and the RFsim, it seems that the scheduler tries to
access the preferred DL TDAs before they have been set after receiving
the cellGroup. In this commit, add a simple check to verify the
preferred TDA has been set up.
