Package:          XML related
Bug Type:         Feature/Change Request
Bug description:Add xml_set_entity_decl_handler function

Description:
------------
When parsing XML, PHP has no way to set a handler for general entities,
though a 
handler can be set for unparsed entities.

Expat has deprecated the XML_SetUnparsedEntityDeclHandler in favor of 
XML_SetEntityDeclHandler, which is called for all entity types (including
general 
and unparsed).

http://expat.cvs.sourceforge.net/viewvc/expat/expat/lib/expat.h?
revision=1.80&view=markup#l_311

PHP should add the xml_set_entity_decl_handler function to allow handling
of all 
entity declarations.


Test script:
---------------
$data = '<!DOCTYPE test [<!ENTITY generalEntity "General
Entity">]><test>&generalEntity;</test>';

function
h_entity_decl($parser,$entity_name,$is_parameter_entity,$value,$base,$system_id,$public_id,$notation_name)
{
	echo "$entity_name - $is_parameter_entity - $value";
};

$parser = xml_parser_create();
xml_set_entity_decl_handler($parser, 'h_entity_decl');

xml_parse($parser,$data,false) or 
    die (sprintf("XML Error: %s at line %d<br>\n", 
				 xml_error_string(xml_get_error_code($parser)),
				 xml_get_current_line_number($parser)));
xml_parser_free($parser);


Expected result:
----------------
It should run with the following output:

generalEntity - 0 - General Entity


Actual result:
--------------
Fatal Error: Call to undefined function xml_set_entity_decl_handler()
