* archive.cc (Archive::total_archives, Archive::total_members) (Archive::total_members_loaded): New variables. (Archive::setup): Add parameter. Add option to preread archive symbols. (Archive::read_armap): Add counter. (Archive::get_file_and_offset): New function. (Archive::get_elf_object_for_member): New function. (Archive::read_all_symbols): New function. (Archive::read_symbols): New function. (Archive::add_symbols): Add counters. (Archive::include_all_members): Use armap to find members if it's already built. (Archive::include_member): Skip reading symbols if already read. Factored code into Archive::get_file_and_offset and Archive::get_elf_object_for_member. Changed call to Mapfile::report_include_archive_member. (Archive::print_stats): New function. * archive.h: Declare Object and Read_symbols_data classes. (Archive::Archive): Add initializers for new members. (Archive::setup): Add parameter. (Archive::print_stats): New function.
