Abstracted '_fix_link_args()' out of 'link_shared_object()'.
Added 'link_static_lib()' method, and 'archiver' and 'archiver_options' class attributes to support it. Added 'link_executable()' method, and 'ld_exec' instance attribute to support it. 'newer_group()' is now able to handle missing files, so we don't have to kludge it by catching OSError when calling it. 'object_filenames()' and 'shared_object_filename()' now take 'keep_dir' flag parameters. 'library_filename()' and 'shared_library_filename()' now respect a directory component in the library name. Various comment updates/deletions.
