[PATCH] Allow get_declared_classes() and get_declared_interfaces() return user/internal class/interface separately

This patch allows get_declared_classes and get_declared_interfaces()
functions to return the information in associative array with "internal"
and "user" keys when passed the optional parameter. And makes them a bit
more consistent with similar functions like get_defined_functions()..

Example:

[jani@localhost php_5_2tst]$ sapi/cli/php -r 'class foobar {}
print_r(get_declared_classes(true));'|less
Array
(
[internal] => Array
(
[0] => stdClass
[1] => Exception
[2] => ErrorException
[3] => __PHP_Incomplete_Class
[4] => php_user_filter
[5] => Directory
[6] => DateTime
[7] => DateTimeZone
)

 [user] => Array
     (
         [0] => foobar
     )

)

Hello Jani,

how about allowing all those functions to return [internal/user], [user],
[internal] or [[internal],[user]] depending on a flag?

best regards
