Clean up caller's name handling. Provide a way for a RADIUS server to set the name to a specific value either on the global level with h323-ivr-in=CNAM:XXX attribute, or on per-route level by using cnam= parameter. The latter takes url-encoded string, while the former - clear coded one. Also get rid of obscure and not very useful logic that kicks in when cli has been set to an empty string and clears up name in this case as well. Require name to be cleared explicitly by either setting CNAM or cnam to an empty string.
