Introduce the SM3 cryptographic hash algorithm (GB/T 32905-2016).
SM3 (GB/T 32905-2016) is a cryptographic standard issued by the
Organization of State Commercial Cryptography Administration (OSCCA)
as an authorized cryptographic algorithm for use within China.
Detect the SM3 cryptographic hash algorithm and enable the feature silently
if it is available.

If the user provides a pre-allocated buffer for the hash result,
we must use that rather than re-allocating a new buffer.

The nettle 2.x series declared all the hash functions with 'int' for
the data size. Since we dropped support for anything older than 3.4
we can assume nettle is using 'size_t' and thus avoid the back compat
looping logic.

Implements the new hashing API in the nettle hash driver.
Supports creating/destroying a context, updating the context
with input data and obtaining an output hash.

QAPI's 'prefix' feature can make the connection between enumeration
type and its constants less than obvious. It's best used with
restraint.
QCryptoHashAlgorithm has a 'prefix' that overrides the generated
enumeration constants' prefix to QCRYPTO_HASH_ALG.
We could simply drop 'prefix', but then the prefix becomes
QCRYPTO_HASH_ALGORITHM, which is rather long.
We could additionally rename the type to QCryptoHashAlg, but I think
the abbreviation "alg" is less than clear.
Rename the type to QCryptoHashAlgo instead. The prefix becomes to
QCRYPTO_HASH_ALGO.

Now that we only support modern nettle, we don't need to have local
typedefs to mask the real nettle types.

It has been over two years since RHEL-8 was released, and thus per the
platform build policy, we no longer need to support RHEL-7 as a build
target. This lets us increment the minimum required nettle version and
drop a lot of backwards compatibility code for 2.x series of nettle.
Per repology, current shipping versions are:
RHEL-8: 3.4.1
Debian Buster: 3.4.1
openSUSE Leap 15.2: 3.4.1
Ubuntu LTS 18.04: 3.4
Ubuntu LTS 20.04: 3.5.1
FreeBSD: 3.7.2
Fedora 33: 3.5.1
Fedora 34: 3.7.2
OpenBSD: 3.7.2
macOS HomeBrew: 3.7.2
Ubuntu LTS 18.04 has the oldest version and so 3.4 is the new minimum.

Nettle version 2.7.x used 'unsigned int' instead of 'size_t' for length
parameters in functions. Use a local typedef so that we can build with
the correct signature depending on nettle version, as we already do in
the cipher code.

Currently the internal hash code is using the gnutls hash APIs.
GNUTLS in turn is wrapping either nettle or gcrypt. Not only
were the GNUTLS hash APIs not added until GNUTLS 2.9.10, but
they don't expose support for all the algorithms QEMU needs
to use with LUKS.
Address this by directly wrapping nettle/gcrypt in QEMU and
avoiding GNUTLS's extra layer of indirection. This gives us
support for hash functions on a much wider range of platforms
and opens up ability to support more hash functions. It also
avoids a GNUTLS bug which would not correctly handle hashing
of large data blocks if int != size_t.
