Avoid unwanted log messages during startup.

Avoid unwanted log messages during startup.

Regardless of the given loglevel, para_recv currently prints log
messages like these at startup:

	afh_init: initializing mp3 handler
	afh_init: initializing ogg handler
	afh_init: initializing aac handler
	afh_init: initializing wma handler
	afh_init: initializing spx handler
	afh_init: initializing flac handler

That's because recv_init() is called before the command line arguments
are parsed, so the loglevel has not been set at this point. Other
programs have similar problems.

Fix these problems by always setting the loglevel right after a parser
has been called so that the init functions run *after* loglevel has
been set.
