init_RU_proc() does not start the ru_thread, this is done by
start_RU_proc()

fix tx_resume_ind_fifo messages sending bugs, rename associated function send_slot_ind() to what it actually does send_dl_done_to_tx_thread()

merge two reduntant and incoherent enums for rnti_type_t, make a macro to stringify properly instead of hardcoded side strings array

While testing the OAI 5G RAN in SA mode, it appears that the PDU session
establishment request is using the wrong security header type.

The current used header is: "Integrity protected and ciphered with new
5G NAS security context".

However, according to TS 24.501, Table 9.3.1, this header can only be used
by the "Security mode complete" procedure.

Changes:

 - Hence, the new security header has been changed to "Integrity protected
   and ciphered", which will use the security context generated during the
   "Security mode complete".

 - Sequences numbers and NAS counters have been updated to reflect that
   change.

* !2487 Rework PUCCH codec with c16_t type and functions to make readable code

* !2499 Update L1sim and RFsim documentation
* !2500 Fix FAPI CoreSetType enumeration options after the fix on the description made by SCF
* !2489 NR UE improvements RRCSetup

- update explanation for noS1
- better help for nr-uesoftmodem options
- consistent writing of name "RFsimulator"
- remove LDPC section at end, is already referenced in doc/README.md

- Add TOC
- Better describe what RFsim does
- Remove misleading, wrong, unnecessary information
  * It is futile to mention --phy-test or other modes, RFsim works with
    all
  * Explaining how to ping is not the task of the RFsim documentation
    (that is what tutorials are for)
  * Remove useless/outdated build log information
- Add some more information on which flags to run
- Improve formatting, and minor clarifications

Merge remote-tracking branch 'origin/NR_UE_harmonize_NAS_registration_accept' into integration_2024_w01

improvements in UE detachment, including sending a message from NAS and signaling to MAC and fixing some memory leaks when terminating UE

SCF FAPI 222.10.02 had a bug on the description of CoreSetType:
0: CORESET is configured by the PBCH or SIB1
(subcarrier 0 of CRB0 for DMRS mapping)
1: otherwise (subcarrier 0 of CORESET)

That was fixed in SCF 222.10.04:
0: CORESET is configured by the PBCH or SIB1
(subcarrier 0 of the CORESET)
1: otherwise (subcarrier 0 of CRB0 for DMRS mapping)

That wrong description created a misunderstanding, to overcome it we "wrongly" added a third value. This commit fixes that and aligns the CoreSetType with FAPI 222.10.04

rework PUCCH codec with c16_t type, rewrite large parts of functions to make readable code. Not fixed parts that are using SIMD. No change, the code is still same block by block (variable visibility narrowed, declaration can be shifted)

- Do not list L1sim as a way of running OAI: it is untested, and might
  not work
- Reword the tutorial where necessary, remove outdated/wrong information
  (e.g., we don't test this mode AFAIK)

Implement RA Contention Resolution timer in gNB accordingly with 3GPP TS 38.321 Section 5.1.5 Contention Resolution

The UE will trigger new RA either with MAC CE C-RNTI or with new RRCSetupRequest:
- MAC CE C-RNTI: The ul_failure_timer will be reset
- RRCSetupRequest: New UE will be created and the previous one will be deleted
