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).

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.)

Creates function that have nr_pdcp_ prepended to their name, and change the signature of some functions for the 5G PDCP: - nr_pdcp_layer_init() - nr_pdcp_data_req() - nr_pdcp_remove_UE() - nr_pdcp_config_set_security() - nr_pdcp_remove_UE() - Make separate functions for nr_pdcp_data_req_srb/drb()

After this commit, only the RNTI is used as an identifier in the MAC. Further, it removes some module_id, but a lot of them remain (the goal to remove all is still far from us)

in fact it syncs the USRP time to GPS time when available and then derives the SFN from the USRP time. a side effect is that now SFN does not necessarily start at 0 and this also required other changes - initialization of the future_ul_tti_request. - fixing a bug in get_samples_per_slot
