This introduces the build logic needed to decide whether we can
use gnutls as a crypto driver backend. The actual implementations
will be introduced in following patches. We only wish to use
gnutls if it has version 3.6.14 or newer, because that is what
finally brings HW accelerated AES-XTS mode for x86_64.

The built-in AES+XTS implementation is used for the LUKS encryption
When building system emulators it is reasonable to expect that an
external crypto library is being used instead. The performance of the
builtin XTS implementation is terrible as it has no CPU acceleration
support. It is thus not worth keeping a home grown XTS implementation
for the built-in cipher backend.

The built-in DES implementation is used for the VNC server password
authentication scheme. When building system emulators it is reasonable
to expect that an external crypto library is being used. It is thus
not worth keeping a home grown DES implementation in tree.

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 gcrypt version and
assume that HMAC is always supported
Per repology, current shipping versions are:
RHEL-8: 1.8.5
Debian Buster: 1.8.4
openSUSE Leap 15.2: 1.8.2
Ubuntu LTS 18.04: 1.8.1
Ubuntu LTS 20.04: 1.8.5
FreeBSD: 1.9.2
Fedora 33: 1.8.6
Fedora 34: 1.9.3
OpenBSD: 1.9.3
macOS HomeBrew: 1.9.3
Ubuntu LTS 18.04 has the oldest version and so 1.8.0 is the new minimum.

If nettle is disabled and gcrypt enabled, the compiler and linker flags
needed for gcrypt are not passed.
Gnutls was also not added as a dependancy when gcrypt is enabled.
Attempting to add the library dependencies at the same time as the
source dependencies is error prone, as there are alot of different
rules for picking which sources to use, and some of the source files
use code level conditionals intead. It is thus clearer to add the
library dependencies separately.

This shows how to do some "computations" in meson.build using its array
and dictionary data structures, and also a basic usage of the sourceset
module for conditional compilation.
Notice the new "if have_system" part of util/meson.build, which fixes
a bug in the old build system was buggy: util/dbus.c was built even for
non-softmmu builds, but the dependency on -lgio was lost when the linking
was done through libqemuutil.a. Because all of its users required gio
otherwise, the bug was hidden. Meson instead propagates libqemuutil's
dependencies down to its users, and shows the problem.
