qapi/crypto: Rename QCryptoHashAlgorithm to *Algo, and drop prefix

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.

glib: bump min required glib library version to 2.40

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

glib: bump min required glib library version to 2.40

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
and new public APIs.

crypto: use glib as fallback for hash algorithm

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.
