New QEMU supports a harsh, but hard to ignore way to notify that the
QMP user used a deprecated command. This is useful e.g. for developers
to see that something needs to be fixed.
This patch introduces a qemu.conf option to enable the setting in cases
when qemu supports it so that developers and continiuous integration
efforts are notified about use of deprecated fields before it's too
late.
The option is deliberately stored as string and not validated to prevent
failures when downgrading qemu or libvirt versions. While we don't
support this, the knob isn't meant for public consumption anyways.

To support domUs with more than 4TB memory it is required to use
LIBXL_API_VERSION >= 0x040800, which uses uint64_t for certained guest
memory related quantities.
Unfortunately this change is not straight forward. While most of the
code in libxl.h handles the various LIBXL_API_VERSION variants
correctly, the check for valid a LIBXL_API_VERSION at the beginning of
the file was broken between Xen 4.7 and 4.13 - it did not cover for
API changes introduced in Xen 4.7 and 4.8. This was fixed with
xen-project/xen@c3999835df, which for libvirt means in practice either
the libxl API from Xen 4.5 or 4.13+ can be used.
This change uses pkgconfig to decide which API can be safely selected.
Xen provides a pkgconfig file since Xen 4.6, which is also the lowest
version expected by libvirt.

types. It was originally mistakenly added to the "scsi-block"
device type too, but later removed. This doesn't affect libvirt
since we restrict usage to device=disk.
When this property is not set then QEMU's default behaviour
is to not report any rotation rate information, which
causes most guest OS to assume rotational storage.

macOS is similar to FreeBSD in that it ships non-GNU versions
of several utilities that we need in the base system.
macOS actually includes GNU make already, but unfortunately due
to licensing reasons the tool is permanently stuck in 2006, so
even in that case users are better off installing a recent
version from Homebrew along with the dozens of other libvirt
dependencies that already need to be obtained that way.
Note that, unlike FreeBSD ports, Homebrew is fully consistent
in adding the 'g' prefix to the name of the GNU tools, so we
can detect GNU grep without additional hacks.

equally wrong.
Therefore, fill in missing bridge names (according to the documentation

When testing locally built daemons on a systemd host there can be quite
a few systemd units that need temporarily stopping, and ideally
restarting after the test is complete. This becomes a massive burden
when modular daemons are running and you want to test libvirtd, as a
huge number of units need stopping.
The run script can facilitate this usage by looking at what units are
running and automatically stopping any that are known to conflict with
the daemon that is about to be run. This is only done when running as
root, since non-root libvirtd does not (currently) use systemd.
