Fixed in tm, tcpops and tls, probably still to do for db_redis and ims_registrar_scscf.

I checked build logs for 754d57f9, looks resolved all except `db_redis` and
`ims_registrar_scscf`.
Comments about resolved warning is hided as outdated.

I pushed earlier today some patches for db_redis and ims_registrar_scscf. As the code
evolved, if there are similar cases, probably is better to open a new issue.
