	Code cleanup.
	* breakpoint.c (clear_command): Remove variable sal_name_len and its
	initialization, remove it from the compare_filenames_for_search call.
	* dwarf2read.c (dw2_map_symtabs_matching_filename): Remove variable
	name_len and its initialization, remove it from the
	compare_filenames_for_search calls.
	* psymtab.c (partial_map_symtabs_matching_filename): Likewise.
	* symtab.c (compare_filenames_for_search): Remove the search_len
	parameter, update the function comment, new variable search_len
	initialized from SEARCH_NAME.
	(iterate_over_some_symtabs): Remove variable name_len and its
	initialization, remove it from the compare_filenames_for_search calls.
	* symtab.h (compare_filenames_for_search): Remove the search_len
	parameter,
