osmo_ortp.c:my_ortp_logfn does not add endline char during log
During osmo-bts processing, I found the following lines all over the place without endlines, and all are related to osmo_ortp.c:
osmo_ortp.c:0 Sending RTCP SR compound message on session [0x7ffff1728f20].20181003200335480 DMEAS ... whatever here....
That's log output coming fro ortp itself. In order to feed the information into our log system, we use function "my_ortp_logfn".
I'd strlen(fmt), then check if last char is '\n', and otherwise use a new buffer and copy fmt + append '\n'.
