#41196: add _doing_it_wrong to get_query_var and prevent fatal errors

 The following scenario will throw a fatal error:

 {{{#!php
 <?php
 function parse_query_fail_test(){
         get_query_var('some_var_name', false);
 }
 add_action('parse_query', 'parse_query_fail_test');

 function parse_query_fail_trigger(){
         get_posts();
 }
 add_action('plugins_loaded', 'parse_query_fail_trigger');
 }}}

 this could easily be avoided with a check and _doing_it_wrong function,
 similar to functions further down such as is_tax();

 I would argue that the same could be done for get_queried_object(),
 get_queried_object_id() and set_query_var()
