	* maint.c (maintenance_info_sections): Pass string argument to
	print_section_table, so that it can be used to select sections.
	(print_section_table): Change PTR to void *.  Look at string arg
	to select sections by name and by flag attributes.
	(match_bfd_flags): New function.
	(print_bfd_flags): New function.
