[PATCH v2 18/19] qapi/cryptodev: Rename QCryptodevBackendAlgType to *Algo, and drop prefix

Markus Armbruster
2024-09-04T11:18:56Z

QAPI's 'prefix' feature can make the connection between enumeration
type and its constants less than obvious. It's best used with
restraint.

QCryptodevBackendAlgType has a 'prefix' that overrides the generated
enumeration constants' prefix to QCRYPTODEV_BACKEND_ALG.

We could simply drop 'prefix', but I think the abbreviation "alg" is
less than clear.

Additionally rename the type to QCryptodevBackendAlgoType. The prefix
becomes QCRYPTODEV_BACKEND_ALGO_TYPE.
