 When a widget is output through a registered sidebar it passes through the
 'widget_display_callback' filter (see 'display_callback' in 'wp-
 includes/widgets.php', allowing for short-circuiting.  This is not the
 case when 'the_widget' is called, however.  This patch simply adds the
 same feature to that function.

 The reason I came across this is because I am using the
 [https://wordpress.org/plugins/display-widgets/ Display Widgets] plugin to
 hide widgets under certain circumstances.  It hooks into
 'widget_display_callback', runs some logic, and returns false if it should
 not appear.  Using 'the_widget' in a template file, I noticed that the
 widget still appeared.

 It seems logical to me that any time a widget is displayed, it should go
 through this filter.
