'qemuBackupJobTerminate' needs the API flags to see whether
VIR_DOMAIN_BACKUP_BEGIN_REUSE_EXTERNAL. Unfortunately when called via
qemuProcessReconnect()->qemuProcessStop() early (e.g. if the qemu
process died while we were reconnecting) the job is cleared temporarily
so that other APIs can be called. This would mean that we couldn't clean
up the files in some cases.
Save the 'apiFlags' inside the backup object and set it from the
'qemuDomainJobObj' 'apiFlags' member when reconnecting to a VM.

This introduces support for the QEMU audio settings that are common to
all audio backends. These are expressed in the QAPI schema as settings
common to all backends, but in reality some backends ignore some of
them. For example, some backends are output only. The parser isn't
attempting to apply restrictions that QEMU itself doesn't apply.

The current <audio> element only allows an "OSS" audio backend, as this
is all that BHyve needed. This is now extended to cover most QEMU audio
backends. These backends all have a variety of attributes they support,
but this initial impl does the bare minimum, relying on built-in
defaults for everything. The only QEMU backend omitted is "dsound" since
the libvirt QEMU driver is not built on Windows platforms.
The SDL audio driver names are based on the SDL 2.0 drivers. It is not
intended to support SDL 1.2 drivers.

The <graphics type="vnc" .... powerControl="yes"/> option instructs the
VNC server to enable an extension that lets the client perform a
graceful shutdown, reboot and hard reset.
This is enabled by default since it cannot be assumed that the VNC
client user has administrator rights over the guest OS. In the case
where the VNC user is a guest administrator though, it is reasonable
to allow direct power control host side too.
