audiod: Deprecate the --no_default_filters option.

This option does not make much sense anymore these days as we have
sane defaults in case no filter was given. We prefer deprecation over
removal because this allows to switch between old and new versions
without having to edit the config file.

The option will be removed after the next release.

        This option may be given multiple times. The \"filter_spec\"
        consists of an audio format specifier (see above), the name
        of the filter, and any options for that filter. Note that
        order matters.
 
+       The compiled-in defaults apply to all audio formats for which
+       no --filter option was given. These defaults depend on the
+       receiver being used.
+
+       For HTTP streams, only the decoder for the current audio
+       format is activated. UDP and DCCP streams, on the other
+       hand, are sent FEC-encoded by para_server. In order to play
+       such streams, the receiver output must be FEC-decoded first,
+       i.e. fed to the fecdec filter. Therefore the default for UDP
+       and DCCP streams is to activate the fecdec filter, followed
+       by the decoding filter for the audio format.

        Examples:
 
                --filter 'mp3:mp3dec'
