laforge has submitted this change and it was merged. ( https://gerrit.osmocom.org/c/libosmocore/+/14478 )

Change subject: cbsp: Introduce osmo_cbsp_errstr
......................................................................

cbsp: Introduce osmo_cbsp_errstr

Rather than having the encoder/decoder library print some log
messages in case of encoding/decoding errors, let's provide something
akin to 'errno', but with a string instead of a numeric error code.

The 'osmo_cbsp_errstr' global variable (if set) contains a
human-readable string describing the most recent encoding/decoding error.

It exists separately for each thread and hence can be used safely in
multi-threaded environments.
