Subject: Remove quick_symbol_functions::map_symtabs_matching_filename

This replaces quick_symbol_functions::map_symtabs_matching_filename
with a call to expand_symtabs_matching.  As with the previous patch,
rather than update all callers, the implementation is consolidated in
objfile::map_symtabs_matching_filename.
