Merge prefix-redefinition-fix branch.
	
	* normal/autofs.c (read_fs_list): Make function capable of being
	run multiple times, gracefuly replacing the previous data
	structures.
	* normal/dyncmd.c (read_command_list): Likewise.
	* normal/handler.c (read_handler_list): Likewise.
	* normal/main.c (read_lists): New function.  Calls all the
	list reading functions.
	(grub_normal_execute): Use read_lists() instead of calling all
	list reading functions explicitly.  Register read_lists() as a
	variable hook attached to ${prefix}.
