Replace Deprecated Init create_function (php 7.2)

Several plugins still use the deprecated function.

EXAMPLE (SSN)
//deprecated version
add_action('widgets_init', create_function('', 'return register_widget("SimpleSectionNav");'));
//7.2 ready version
function ssn_register_widget() { return register_widget("SimpleSectionNav"); }
add_action( 'widgets_init', 'ssn_register_widget' );

EXAMPLE
//deprecated version
add_filter( 'option_page_capability_' . ot_options_id(), create_function( '$caps', "return '$caps';" ), 999 );
replace with
//7.2 ready version
add_filter( 'option_page_capability_' . ot_options_id(), function($caps) {return $caps;},999);

EXAMPLE (OZH MENU)
//deprecated version
add_action('admin_notices', create_function( '', "echo '$message';" ) );
replace with
//7.2 ready version
add_action( 'admin_notices', function() {echo $message;} );
