T tracer was not functional anymore. because init_tpools() was called
before T_Config_Init().

The problem was that init_tpools() creates some threads and T_Config_Init()
does call fork() and the child process (which is the one running the
softmodem, the parent process is used to monitor it, this is the design
of the T tracer, maybe to change at some point, it's too complicated) has
no thread after the fork(). The threads created by init_tpools() are gone.
Game over.

In conclusion: T_Config_Init() has to be called very early in the life of
the softmodem, at least before init_tpools().

MR !1353: L1 Tx threading update 
Removed active waiting loop which could block threads. Instead a separate thread to reorder the finished job is used.

MR !1371: NR UE capabilities
-Capabilities for OAI UE from xml file (for now copy-pasted from a COTS UE, to be modified in the framework of harmonization of RRC configuration at gNB).
-For phy-test and do-ra mode, the gNB directly reads the xml file.

MR !1397: fix issue created from fix int8 overflow (int8 overflox is small)
-ptrs computation was making uint8 overflow, i fixed it, but then, as the overflow is negative, it became a very high positive number (uint8 0-1 is "only" 255)

MR !1390: ci-improvements
-store executables with which core dumps have been created for better analysis 
-do not capture GTP, bloating PCAPs 
-complete + order build_oai help 
-build all libraries in containers (e.g., nrscope, telnet, ...) 
-increase (containerized, 5G) RFsim throughput and tentatively analyze
