Support queries for attribute length and presence.
Calling hal_rpc_pkey_get_attributes() with attribute_buffer_len = 0 now changes the return behavior so that it reports the lengths of attributes listed in the query, with a length of zero for attributes not present at all. This is mostly to support C_GetAttributeValue() in PKCS #11, but we also use it to make the Python interface a bit kinder to the user.
