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

PDU Length is as per SCF 222.10.02: The total length (in bytes) of the PDU description and PDU data, without the padding bytes. From TX_DATA.request we get 8 (2 bytes PDU_Length + 2 bytes PDU_Index + 4 bytes num_TLV ) and from each TLV we get 4 + value size ( 2 bytes tag + 2 bytes length + value size without pading) Therefore, add function to compute PDU_length() value for TX_Data.request, taking into account how many TLVs there are. compute_PDU_length() does not rely on access to `nfapi_nr_pdu_t`. Put it into nr_mac_common.c to avoid introducing dependencies.

!SIB1 is not correctly filled! This commit does not work with COTS UEs! The next commit fixes this. - Move radio config (e.g., minRXTXTIME, SIB1 TDA, do_SRS, etc) down to MAC. - Some parameters in MAC are redundant: delete them. - Remove call to nr_mac_config_scc() from RRC and simulators, the MAC initialization routine calls it implicitly

This time constant plays a major role in how long a UE has to wait maximally before it might be scheduled. For instance, if a UE had a lot of traffic, the average traffic will be high, pushing the PF coefficient down. If another UE with no traffic in the past becomes active with heavy traffic, the first UE might not be scheduled for an extended period of time. In the AW2S-Amarisoft UE CI test pipeline, we sometimes see that the maximum number of RLC retransmissions was reached. While this might not be the (only) cause, scheduling a UE more often might prevent such situations, and we saw an improved stability.

Different threads (e.g., RRC, DU tasks) might access the scheduler at the same time as the thread that drivers the scheduler itself (ru_thread). To avoid data races, introduce this mutex. Most functions of the scheduler are only used internally and have been marked static in the previous commit. The remaining ones, in this commit, either lock the scheduler mutex sched_lock, or a comment has been added of the assumption of how such function is to be locked (e.g., if it might be called from different places, or if it is called by a function that already locks the scheduler).

To know which functions are used from outside and which are module-local, make many functions static. This will allow us to protect only those functions with a mutex for which it is necessary.

This commit fixes a bug caused by global variables in the gNB_MAC_INST structure used to transfer MAC scheduler's results to the PHY layer. When using several threads in the PHY layer, it may happen that the MAC scheduler is called a second time by the second PHY thread for the next slot before the content of the global variables in the gNB_MAC_INST structure used to store the result of the MAC scheduler for the current slot have been consumed by the first thread, leading to unpredictable results (all of them certainly wrong). The solution is to introduce a small memory management module for the interface between the PHY threads and the MAC scheduler. The MAC scheduler now fills the data structures passed to it, and not a global variable anymore. The PHY layer manages the structures and ensures that no data is overwritten before being fully consumed by the various threads of the PHY layer. Some care has to be taken because several PHY threads will access the same structures at the same time for a given slot (in read mode, so it's okay). A mechanism of reference counting has thus been introduced. Only one CC is supported. This restriction should not be too hard to remove if/when needed. (The code before this commit does not seem to work for more than one CC anyway.)

- reusing old TDA whenever possible helps allocate DL retransmission when TDA chnges - e.g. nrOfSymbols of new TDA > nrOfSymbols old TDA (leading to TBS size mismatching and allocation failure) - This bugifx improves DL throughput stability in a multi-UE operation

- The qsort() function is defined as: void qsort(void *base, size_t nmemb, size_t size, int (*compar)(const void *, const void *)); and sorts an array with nmemb elements of size size. - in the gNB scheduling functions, nmemb and size were swapped - this was causing a stack overflow ending with a SEGFAULT under certain circumstances
