Integration of O-RAN 7.2 FH using OSC xRAN library

• Add new 7.2 FHI library under radio/fhi_72; leverages OSC xRAN lib (fhi_lib, E release)
• Add instructions/tutorial for compilation
• Various fixes to support this library:
  • thread pool threads have maximum priority
  • new config option for enable/disable phase compensation (because we don't have 7.2 M plane, which negotiates where phase compensation happens)
  • modify default timing advance not necessary, default is fine
  • avoid memcpy of txdataF_BF if no precoding to minimize memcpys
  • load transport library load at the beginning of the RU thread, for symmetry with split 8 lib load and for 7.2 interoperability
  • Add some split 7 configuration parameters in openair0_config (split 8 interface) for 7.2 interoperability
  • maximum openair0_config number of antennas at 8
  • minor fixes for logging, asserting, fixes for stopping threads (see commit messages)

Tests:

• LiteOn FlexFi
• Benetel 650
• VVDN

requested review from @Cedric.Roux

mentioned in merge request !2330 (closed)

@defosseu the last commit for CI integration is IMO not relevant anymore, as we don't really need these environment variables. I will provide an update where OAI will download and build the xRAN library itself, then we don't have to do anything except for installing DPDK beforehand.

I still have to incorporate your feedback:

• In Section 3.1 just put a comma before in our environment we are using
• For the fhi_72 section part, little typo mac-addrees. Also I would put some examples on the MAC addresses, from one of the above-mentioned files but it might overload a bit that section. For example the DU one (`du_addr = ("00:11:22:33:44:99", "00:11:22:33:44:99"); ) is a SW version and is kinda hardcoded in the code?
• Last point in the conf file, the fh_config section parameters have to be provided by the RU manufacturor, isn't it? it might be worth mentioning?
• And finally still in this fh_config maybe for you it's obvious, but I would add a definition in comment for each field. And if we could refer to the RU user guide, that would be perfect if we can.
