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. Change-Id: Id9a5a595a76ba278647aee9470ded213d8464103
