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

Implements the new hashing API in the GLib 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.

QEMU requires minimum glib version 2.66.0 as per the root meson.build
file and per glib documentation[1] G_CHECKSUM_SHA384 is available since
2.51.

It's either "GNU *Library* General Public License version 2" or "GNU
Lesser General Public License version *2.1*", but there was no "version
2.0" of the "Lesser" license. So assume that version 2.1 is meant here.

Per supported platforms doc[1], the various min glib on relevant distros is:
RHEL-7: 2.50.3
Debian (Stretch): 2.50.3
Debian (Jessie): 2.42.1
OpenBSD (Ports): 2.54.3
FreeBSD (Ports): 2.50.3
OpenSUSE Leap 15: 2.54.3
SLE12-SP2: 2.48.2
Ubuntu (Xenial): 2.48.0
macOS (Homebrew): 2.56.0
This suggests that a minimum glib of 2.42 is a reasonable target.
The GLibC compile farm, however, uses Ubuntu 14.04 (Trusty) which only
has glib 2.40.0, and this is needed for testing during merge. Thus an
exception is made to the documented platform support policy to allow for
all three current LTS releases to be supported.
Docker jobs that not longer satisfy this new min version are removed.

and rename them with "nettle/gcrypt/glib" prefix.
2) introduces hash framework, including QCryptoHashDriver

GLib >= 2.16 provides GChecksum API which is good enough
for md5, sha1, sha256 and sha512. Use this as a final
fallback if neither nettle or gcrypt are available. This
lets us remove the stub hash impl, and so callers can
be sure those 4 algs are always available at compile
time. They may still be disabled at runtime, so a check
for qcrypto_hash_supports() is still best practice to
report good error messages.
