* random.c: replace with Mersenne Twister RNG.
* eval.c (jump_tag_but_local_jump): preserve retval in LocalJumpError exceptions. * parse.y (command): no more check for "super outside of method". * eval.c (rb_mod_define_method): should set last_class and last_func in the block->frame. * eval.c (error_handle): should handle TAG_THROW as well. * parse.y (yylex): new decimal notation '0d4567'. * parse.y (yylex): new octal notation '0o777'. * parse.y (string_content): every string_content node should return string only. use NODE_EVSTR to coercing. * eval.c (rb_eval): NODE_EVSTR support. * re.c (rb_reg_quote): avoid unnecessary string allocation. * string.c (get_pat): quote metachracters before compiling a string into a regex. * string.c (rb_str_split_m): special treatment of strings of size 1, but AWK emulation. now uses get_pat(). * string.c (rb_str_match_m): quote metacharacters. * string.c (rb_str_match2): ditto. * ext/socket/socket.c (sock_addrinfo): make all 3 versions of getaddrinfo happy.
