add osmo_bcd2str()
Add a standalone bcd-to-string conversion function with generic parameters. Add a regression test in utils_test.c. So far there is no single universal implementation that converts a BCD to a string. I could only find gsm48_mi_to_string(), which also interprets surrounding bytes, MI type and TMSI as non-BCD value. The idea is to use this function from gsm48_mi_to_string() and similar implementations in subsequent commits. Root cause: in osmo-msc, I want to have an alternative MI-to-string function for composing an FSM name, which needs the BCD part of gsm48_mi_to_string() but not the TMSI part.
