So a bit more testing shows that MS behavior is inconsistent between
HashAlgorithm implementations. Some requires a call to Initialize (e.g. MD5,
SHA1) while others do not (e.g. SHA256|384|512, most HMACs...).

Since Mono shares more code between implementations (all managed) than MS
(mixed managed / native implementation) having different behavior is a bit more
difficult.

The way we have it now is that code working on MS .NET will work, unmodified,
on Mono (a very good thing) - while code working on Mono could, depending on
the HashAlgorithm, break when executed on MS (but changing our behavior could
break existing Mono apps too).
