spice_server_set_channel_security() is already mostly doing that. We can
make its code more generic, and introduce a red_channel_get_name()
method. This method will then be used to make debug messages more
readable by showing the actual channel name rather than its type as
an int.

Changes since v1:
- Moved smartcard special-casing to red_channel_name_to_type
- Added some API documentation to the 2 new functions
