Description:
------------
PHP 5.3 seems to have missed a few things internally (macro-wise) when it comes to namespaces. When developing an extension for 5.3, I noticed the following:

Zend/zend_API.h:93
#define ZEND_NS_NAMED_FE(ns, zend_name, name, arg_info)

It's blank! I do not see any options to submit patches, therefore, this should be the definition:

#define ZEND_NS_NAMED_FE(ns, zend_name, name, arg_info) \
    ZEND_NS_FENTRY(ns, zend_name, name, arg_info, 0)


In addition, PHP_NS_* aliases are missing for the ZEND_NS_* macros. For example, PHP_FE is an alias to ZEND_FE. Therefore, the following macros should be added:

#define PHP_NS_FE         ZEND_NS_FE
#define PHP_NS_NAMED_FE   ZEND_NS_NAMED_FE
#define PHP_NS_DEP_FE     ZEND_NS_DEP_FE
#define PHP_NS_FALIAS     ZEND_NS_FALIAS
#define PHP_NS_DEP_FALIAS ZEND_NS_DEP_FALIAS

If you could provide me with a means to submit a patch, I would be more than happy to do it myself, as I feel this to be an important (albeit minor) addition for extension developers in order to keep things consistent, and less confusing.

Reproduce code:
---------------
zend_function_entry php_test_functions[] = {
    ZEND_NS_NAMED_FE( "Ns", myfunc, test_myfunc, NULL )
    { NULL, NULL, NULL }
};

---

<?php var_dump( get_extension_funcs('test') ); ?>


Expected result:
----------------
array(1) {
  [0]=>
  string(16) "Ns\myfunc"
}

Actual result:
--------------
array(0) {
}
