The Parrot_call_sub function had been deprecated and removed. All uses
of it should be replaced with Parrot_ext_call, which is tested. The
primary difference between the two functions is the signature string
format. Parrot_ext_call uses the new PCC-style signature strings,
while Parrot_call_sub used an older style.

If you need any help with the conversion, let me know.
