The qcrypto_hash_digest_len method was accidentally inside
a CONFIG_GNUTLS_HASH block, even though it doesn't depend
on gnutls. Re-arrange it to be unconditionally defined.

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

The QCryptoHashAlgorithm enum is defined in the crypto/hash.h
header. In the future some QAPI types will want to reference
the hash enums, so move the enum definition into QAPI too.

Add a qcrypto_hash_digest_len() method which allows querying of
the raw digest size for a given hash algorithm.

Introduce a new crypto/ directory that will (eventually) contain
all the cryptographic related code. This initially defines a
wrapper for initializing gnutls and for computing hashes with
gnutls. The former ensures that gnutls is guaranteed to be
initialized exactly once in QEMU regardless of CLI args. The
block quorum code currently fails to initialize gnutls so it
only works by luck, if VNC server TLS is not requested. The
hash APIs avoids the need to litter the rest of the code with
preprocessor checks and simplifies callers by allocating the
correct amount of memory for the requested hash.
