Fix number of required arguments in arginfo

* pack() only requires one argument
* stream_context_set_option() only requires two arguments
* ReflectionMethod::getClosure() accepts no args for static methods
* DOMDocument::createProcessingInstruction() only requires one arg
* DOMImplementation::createDocument() only requires two arguments
* DOMDocument::importNode() only requires one arg
* mysql_get_client_version() doesn't accept any args,
  despite what the docs say...
