Test-crypto-hash calls qcrypto_hash_bytesv/digest/base64 with
errp=NULL, this will cause a NULL pointer dereference if afalg_driver
doesn't support requested algos:
ret = qcrypto_hash_afalg_driver.hash_bytesv(alg, iov, niov,
result, resultlen,
errp);
if (ret == 0) {
return ret;
}
error_free(*errp); // <--- here
Because the error message is thrown away immediately, we should
just pass NULL to hash_bytesv(). There is also the same problem in
afalg-backend cipher & hmac, let's fix them together.

Adds afalg-backend hmac support: introduces some private APIs
firstly, and then intergrates them into qcrypto_hmac_afalg_driver.

1) makes the public APIs in hmac-nettle/gcrypt/glib static,
and rename them with "nettle/gcrypt/glib" prefix.
2) introduces hmac framework, including QCryptoHmacDriver
and new public APIs.
