psymtab cleanup patch 3/3

This last patch removes "partial" from the names of
expand_partial_symbol_names and map_partial_symbol_filenames.
It also renames expand_partial_symbol_names to match the
struct quick_symbol_functions "method" that it wraps:
expand_symtabs_matching.

This patch also adds two parameters to expand_symtabs_matching
so that it can fully wrap the underlying quick_symbol_functions method.
This makes it usable in more places.
I thought of having a cover function that still had the same
signature as the old expand_partial_symbol_names function,
but I couldn't think of a good name, and it wasn't clear it was
worth it anyway.

	* symfile.h (expand_symtabs_matching): Renamed from
	expand_partial_symbol_names.  Update prototype.
	(map_symbol_filenames): Renamed from map_partial_symbol_filenames.
	* symfile.c (expand_symtabs_matching): Renamed from
	expand_partial_symbol_names.  New args file_matcher, kind.
	Rename arg fun to symbol_matcher.
	(map_symbol_filenames): Renamed from map_partial_symbol_filenames.
	* ada-lang.c (ada_complete_symbol_matcher): Renamed from
	ada_expand_partial_symbol_name.
	(ada_make_symbol_completion_list): Update to call
	expand_symtabs_matching.
	(ada_add_global_exceptions): Call expand_symtabs_matching.
	* mi/mi-cmd-file.c (mi_cmd_file_list_exec_source_files): Update to
	call map_symbol_filenames.
	* symtab.c (sources_info): Update to call map_symbol_filenames.
	(search_symbols): Call expand_symtabs_matching.
	(symbol_completion_matcher): Renamed from expand_partial_symbol_name.
	(default_make_symbol_completion_list_break_on): Update to call
	expand_symtabs_matching.
	(make_source_files_completion_list): Update to call
	map_symbol_filenames.
