......................................................................

hodec2: log requirements of best candidate, log rxlev in dBm

Instead of logging a hex value for the met requirements, fully expand the "ABC"
flags for both TCH/F and TCH/H.

>From HO_CANDIDATE_FMT/_ARGS, split off into REQUIREMENTS_FMT/_ARGS and use that
when logging the chosen HO candidates.

Also change the RX level to dBm, to match general logging and reduce confusion
between rxlev number variants in the log.
