faluco fa351cd285 Rename functions that contain the unsafe word to nolock.
The term "unsafe" does not clearly state that the function is not locking the shared date and it sounds "dangerous", so use a more explicit term.

It also adds a Msg3 unit test.

building on the previous refactor this patch now adds support
for peridoic BSR reporting (using short BSR). It furthermore does
the following changes:

* add BSR packing
* add proc_bsr_nr unit test
* move mac_nr test code into test folder under src (needs to be done with other test code too)

Andre Puschmann 9c4146442a mac,phy: refactor NR MAC/PHY UL data passing interface
inspired by accepted (but not yet merged) PR to include the
(unique_)byte_buffer_t for MAC/PHY interfacing, this patch adds
a few more useful bits to that. Buffer management for UL data is now
done in MAC and only a pointer to the data is passed in the UL action.

* Move Tx softbuffer to MAC (until UL HARQ class is ready)
* Remove temparal data member in cc_worker
* Remove memcpy after packing MAC PDU

Andre Puschmann 8e13f04684 mac_pcap: refactor MAC PCAP and include NR RAT into same object
after adding the thread-safe PCAP writer functionality to the EUTRA
MAC object it became clear that we don't wont to replicate the
same for the NR object.

This patch therefore refactors the class that now supports both EUTRA and
NR rats. The old mac_nr_pcap.[h/cc] has been deleted. All test-cases
and usages now use the new object that needs to pass the RAT type in
the ctor.

this patch addresses the last open point of #2160
