the variables are not declared in the function header,Inconsistent with the overall style,

这个不算什么问题，在 src / ngx_http_lua_util.c 文件的 227行， 如下

lua_State *cr = lua_tothread(L, -1);

变量 cr 没有申明在函数的头部， 与总体风格不一致，此外在c90编译器中报错。

I've been working hard to eliminate things like this. I definitely missed this one in my last code review ;) Already fixed in git master HEAD. Thanks for the catch!
