2021-07-14crypto: add gnutls cipher providerDaniel P. Berrangé
Add an implementation of the QEMU cipher APIs to the gnutls crypto backend. XTS support is only available for gnutls version >= 3.6.8. Since ECB mode is not exposed by gnutls APIs, we can't use the private XTS code for compatibility. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
