Description:
------------
When registering a function with xml_set_end_namespace_decl_handler this function is never called. This is very similar to Bug #30061 "xml_set_start_namespace_decl_handler not called" which is now closed.

Reproduce code:
---------------
<?php

$xml = '<addressbook xmlns:ab="http://www.somewhere.com/addressbook/" />';

$parser =& xml_parser_create_ns();
xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);

xml_set_start_namespace_decl_handler($parser, "NSStartHandler");
xml_set_end_namespace_decl_handler($parser, "NSEndHandler");

xml_set_element_handler($parser, 'StartHandler', 'EndHandler');
xml_parse($parser, $xml, true);
xml_parser_free($parser);

function StartHandler($parser, $name, $attrs) {print("StartHandler Called\n");}
function EndHandler($parser, $name) {print("EndHandler Called\n");}
function NSStartHandler($parser, $prefix, $uri) {print("NSStartHandler Called\n");}
function NSEndHandler($parser, $prefix) {print("NSEndHandler Called\n");}

?>


Expected result:
----------------
NSStartHandler Called
StartHandler Called
EndHandler Called
NSEndHandler Called

Actual result:
--------------
NSStartHandler Called
StartHandler Called
EndHandler Called
