Find or create a conference.

Parameters:

	confno	The conference name/number
	pin	The regular user pin
	pinadmin	The admin pin
	make	Make the conf if it doesn't exist
	dynamic	Mark the newly created conference as dynamic
	refcount	How many references to mark on the conference
	chan	The asterisk channel

Returns:

A pointer to the conference struct, or NULL if it wasn't found and make or dynamic were not set.
