(addrinfo_mload): new method. (Init_addrinfo): define the method above. * ext/socket/constants.c (constant_arg): str_to_int's first argument constified. * ext/socket/mkconstants.rb (gen_name_to_int_decl): generated function's first argument constified. (gen_name_to_int_func_in_guard): ditto. (ipproto_to_int): generated. * ext/socket/rubysocket.h (IS_IP_FAMILY): moved from raddrinfo.c. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@21643 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
