This makes it possible to reduce the number of cases we have to
consider, because 'sles' declares itself to be like 'suse' and
both 'rhel' and 'centos' declare themselves to be like 'fedora'.
We have to move the check for Ubuntu before the one for Debian,
however, because 'ubuntu' declares itself to be like 'debian'
and it would end up with the wrong defaults otherwise.

An update to meson 0.61.1 meant that it started showing warnings due to the fact
that the default for run_command's 'check' parameter is going to change. It
unveiled the fact that we were even missing that parameter in some calls where
we expected different outcome. To make sure the behaviour does not change
specify the parameter explicitly. In places where we check for the return code
the parameter should be 'false' so that meson does not fail. In all other cases
the parameter should be set to 'true' to make sure possible failure also stops
meson.

While it's true that our virCommand subsystem is happy with
non-absolute paths, the dnsmasq capability code is not. It stores
the path to dnsmasq within and makes it accessible via
dnsmasqCapsGetBinaryPath(). While strictly speaking no caller
necessarily needs canonicalized path, let's find dnsmasq once and
cache the result.
Therefore, when constructing the capabilities structure look up
the binary path. If DNSMASQ already contains an absolute path
then virFindFileInPath() will simply return a copy.
With this code in place, the virFileIsExecutable() check can be
removed from dnsmasqCapsRefreshInternal() because
virFindFileInPath() already made sure the binary is executable.
But introducing virFindFileInPath() means we have to mock it in
test suite because dnsmasqCaps are created in
networkxml2conftest.
Moreover, we don't need to check for dnsmasq in configure.

We need libparted to be available at build time otherwise we

for other commands, we already perform a lookup through the
virCommand API so making sure it's available at build time
is unnecessary.
This doesn't make any difference for platform such as Fedora

have separate packages for the two components and this change

Recently, FreeBSD has got sched_get/setaffinity(3) implementations and
the sched.h header as well [1]. To make these routines visible,
users have to define _WITH_CPU_SET_T.
This breaks current detection. Specifically, meson sees the
sched_getaffinity() symbol and defines WITH_SCHED_GETAFFINITY. This
define unlocks Linux implementation of virProcessSetAffinity() and other
functions, which fails to build on FreeBSD because cpu_set_t is not
visible as _WITH_CPU_SET_T is not defined.
For now, change detection to the following:
- Instead of checking sched_getaffinity(), check if 'cpu_set_t' is
available through sched.h
- Explicitly check the sched.h header instead of assuming its presence
if WITH_SCHED_SETSCHEDULER is defined

There is no guarantee that QEMU and libvirt have been configured
with the same prefix.
In particular, Homebrew on macOS will pass a different, private
prefix for each package version and then use symlinks to make
the files for a specific version appear in the usual locations.
This works perfectly fine as long as one package doesn't try to
go poking around another package's data - which is exactly what
libvirt needs to do in order to read and parse the QEMU interop
data.
qemu_datadir can now be explicitly provided to make this and
other uncommon scenarios work. The common scenario, where QEMU
and libvirt both use the same prefix, is unaffected.

With the traditional libvirtd, the virConnectOpen call will probe active
drivers server side to find which one to use when the URI is NULL/empty.
With the modular daemons though, the remote client does not know which
daemon to connect in the first place, so we can't rely on virConnectOpen
probing. Currently the virtproxyd daemon has code to probe for a
possible driver by looking at which sockets are listening or which
binaries are installed. The remote client can thus connect to virtproxyd
which in turn can connect to a real hypervisor driver.
The virtproxyd probing code though isn't something that needs to live in
virtproxyd. By moving it into the remote client we can get probing
client side in all scenarios and avoid the extra trip via virtproxyd in
the common case.
