Bug#1077060: Regression in switch to gnutls: pkcs11 and pkcs12 no longer available

[Sam Hartman]

I try something like
curl --cert 'pkcs11:manufacturer=piv_II'
And I get an error:
curl: (3) URL rejected: Port number was not a decimal number between 0
and 65535

Yet I think that's a valid pkcs11 URL.
