Use own function for symbol name matching on Windows (bug #64975). * glob-match.h, glob-match.cc (symbol_match): Add new class that can efficiently match symbol names cross-platform. * call-stack.cc (call_stack::clear_global_variable_pattern), load-save.cc (matches_patterns, load_save_system::save_fields), ls-hdf5.cc (read_hdf5_data), stack-frame.cc (symbol_cleaner::clear_symbols, symbol_info_accumulator::filter), symtab.cc (symbol_table::clear_function_pattern), variables.cc (name_matches_any_pattern): Use new class to match symbol names. * variables.cc (Fclear): Update docstring to point to difference of patterns on Windows.
