Change 96025 by jb at jb_freebsd2 on 2006/04/24 23:28:05

	Use the new linker_file_list function to iterate over the loaded
	modules.
	
	Change the references to 'struct modctl' to modctl_t which is declared
	in Solaris and is consistent with the rest of their code. They usually
	use the 'foo_t' type defines in preference to 'struct foo'. It's
	easier for us to compatible-ise to foo_t.
