Get rid of direct use of gnutls APIs in quorum blockdrv in favour of using the crypto APIs. This avoids the need to do conditional compilation of the quorum driver. It can simply report an error at file open file instead if the required hash algorithm isn't supported by QEMU. Signed-off-by: Daniel P.
