[gnutls-devel] GnuTLS | Fix gnutls_pkcs11_token_get_info for short output buffers and fix a memleak (!827)

[Development of GNU's TLS library]

Nikos Mavrogiannopoulos commented on a discussion on lib/pkcs11.c:

>  		len = p11_kit_space_strlen(str, str_max);
>  
>  	if (len + 1 > *output_size) {
> -		*output_size = len + 1;

The rule in such functions is to return `full_size+1` when returning the short memory buffer error, and the `full_size` when returning the actual data. Is that missing from the function you mention? Is there something we should improve in the documentation?
