Add Fedora 41, build_oai cleanup
- Add Fedora 41 to list of supported distributions
- Remove some dependencies in RHEL that are not necessary
- Cleanup some build_oai documentation of non-supported options
Simplify logs in gNB&UE
- reduce the amount of printf() that outputs useless info
- in MAC, PHY, NGAP, RRC, mark some "important" UE events with LOG_A for
better visibility -> can put log_config.global_log_level analysis to
only see important stuff
- in RRC, use some macro to consistently print logs
- track the cellID of a UE in RRC
small fix for 3 digit mnc usage in sib1
When 3 digit MNC is used in PLMN, during preparation of SIB1, first
digit of MNC was not taking into account. UE derives Serving Network
Name (SNN) using PLMN info from sib1. Because of 5GCore and UE has
different SNNs, this leads to XRES*, RES* mismatch during Authentication
Procedure between 5GCore and UE. (SNN is used for derivation of these
keys)
Add functional DFT test
- clean up code on (i)dft calls
- add DFT test for some DFT sizes against trivial implementation: it
tests a simple square signal in only real values
- correctly scale DFT-16
Moved some functions around so that instead of a function pointer a function
call is used. This enables inlining of functions which reduces number of function calls.
During preparation of SIB1, first digit of MNC was not taking into account.
This leads to XRES*, RES* mismatch during Authentication Procedure between 5GCore and UE because of derived serving network names.
This commit removes many logs that just show memory addresses, indices,
etc., which, I presume, do not mean anything to the "average user" and
developers alike.

This MR removes limitations on BWP scheduler operation for which only
the information from the first UE of the list was taken into account. To
do so, I moved the VRB map check for DL and UL scheduler out of the
preprocessor and in the scheduler itself.
Closes: #769
Update yaml-cpp dependency handling
- Added CPM fallback in case package is not found automatically.
- Using yaml-cpp::yaml-cpp target instead of yaml-cpp to silence
deprecation warnings on newer cmake versions.
By omitting the variable CPM_SOURCE_CACHE as CACHE'd, it is actually
given to CPM, but does not appear when viewing it's content, e.g.,
through ccmake. Mark is as CACHE so that it will also appear.

warnings on newer cmake versions.
Add F1 Handover procedures
- Clean up at RRC and MAC
- Add DU handover procedures, completely handle CellGroupConfig at DU
- Add CU handover procedures
- Maintain reestablishment working between/after handover
- Changes at UE to resync on different frequency DUs
