SIB19 utilization on UE
Following SIB19 initialization and scheduling on gNB (!2899 - merged)
and Receive SIB19 on nrUE (!2920 - merged), this merge request aims to
introduce the actual use of the SIB19 provided parameters by gNB in UE.
Changes needed for utilization include: initialization of position
coordinates parameters for UE (which are needed to calculate propagation
delay between UE and SAT), propagation delay calculations and timing
advance adjusts. Moreover, this change removes the now unused arguments
for ntn_koffset, ntn_ta_common and ntn_ta_commondrift
GTP: use direct call instead of ITTI
Using ITTI calls for user plane implies (1) a memory allocation, (2)
mutexes, and (3) queueing messages for each user plane packet, which is
heavy. Use a direct API call instead to reduce overhead.
- Removed ntn_koffset, ntn_ta_common, ntn_ta_commondrift arguments in order to be used directly from SIB19
- Removed global NTN_UE_Koffset variable and it's use
- Introduced getter functions for ntn related parameters

mutexes, and (3) queueing messages for each user plane packet, which is

- Added new structure to hold timing advance parameters
- Made SIB19 related calculation to save to this struct
- Modified in ra to get ta struct values
remove un-necessary global variables
Remove global variables that can be removed by a trivial way:
- simply dead globals
- or reference is a single source, so can be static
setting them static reduces the scope, that is a progress, but of course as
for all static variables, the code is still not re-entrant
T tracer: add macpdu traces for the NR UE
MIB, SIB1, random access and regular scheduling are traced.
At the beginning of a connection (rrc setup request and rrc setup), the
RNTI is reported as 0. Might be fixed, somehow, if absolutely needed (not
sure).
- removed some whitespace noise.
- cleaned up CMakeLists.txt
- reintegrated task_manager.c into thread-pool.c
- cleaned up some unnecessary code

FAPI P7 Refactoring and unitary test creation
This MR is a follow-up to the work done in !2714 this time separating
the P7 FAPI messages into its own library (nr_fapi_p7).
In the same way, utility functions to copy, free and compare have been
added for each message, as well as an addition function to get the
allocated size for a message, which is used for the messages that can be
too big to fit in a buffer that's allocated in the stack.
Unitary tests have been added for each of the messages, testing
pack/unpack and the utility functions added.
Renames nfapi_nr_srs_reported_symbol_t prgs into *reported_symbol_list for two reasons:
So that the name is more representative of what the parameter represents.
For it to actually be a list, and not assume only 1 reported symbol is used.
Allocate reported_symbol_list in unpack_nr_srs_beamforming_report.
Updated all references to prior prgs to point to the first position of reported_symbol_list, still only effectively using the first reported_symbol.
Rename fill_srs_reported_symbol_list into fill_srs_reported_symbol and update input parameter name, since it only fills the information related to one reported symbol
Update NR P5 and P7 nFAPI headers to have 32-bit message_length
In the NR functions, this causes the header parameters following message_length to have their position shifted by 2 bytes, due to the increase in message_length size.
Change needed to accommodate SCF222.10.02 Table 3-3
Separates nfapi_p4_p5_message_header_t and nfapi_nr_p4_p5_message_header_t
Change the callbacks signature to accept/return void* intead of expecting a particular header type, being the NR/LTE distinction done inside the callback functions.
Create NR related functions for nFAPI transmit timestamp and checksum calculation.
Move nfapi_p7_codec_config_t and nfapi_p4_p5_codec_config_t to separate header to be shared between LTE and NR VNF/PNF
Move nfapi_nr_timing_info_t into NR header.
Move NR specific function declarations to NR header.
NR UE RRC T304 in phy-test mode
RRC timer T304 is stopped upon completion of the associated RA handover
procedure. There is no RA procedure in phy-test mode so T304 should not
be started to avoid unwanted expiration.
NR MSG3 scheduling improvements
- fix wrong condition on MSG3 allocation assertion message
- remove assertion altogether and handle properly the case where MSG3
can't be allocated
* tac is optional IE, and it was assumed as always present
* is now allocated in DU container by copy_f1ap_served_cell_info
when present in the updated cell info and missing in the
DU container
