0046e0b1c2 qemuxml2argvtest: Use internal wrapping of command line arguments
virCommandToString has the possibility to return an already wrapped
string with better format than what we get from the test wrapper script.

The main advantage is that arguments for an option are always on the
same line which makes it more easy to see what changed in a diff and
prevents re-wrapping of the line if a wrapping point moves over the
threshold.

Additionally the used output is the same we have in the VM log file when
a VM is starting.

43c9c0859f qemu: use long on|off syntax for -chardev boolean option values
The preferred syntax for boolean options is to set the value "on" or
"off". QEMU 7.1.0 will deprecate the short format we currently use.

The long format has been supported with -chardev since at least 1.5.3,
so we don't need to check for it.

0279a51b83 tests: fix name of 32-bit x86 QEMU binary
The 32-bit x86 binary is called qemu-system-i386, not
qemu-system-i686. This mistake across many test XML files was
not noticed because the mistake was also made in testutilsqemu.c
when mocking the capabilities.

9b3df94ac4 qemuxml2argvtest: Switch to modern vfio backend
The pci-assign device is so old school that no one uses it. All
modern systems have adapted VFIO. Switch our xml2argv test too.

1737d11e1b qemuBuildPCIHostdevDevStr: Always format PCI domain onto cmd line
While it's true that older QEMUs were not able to deal with PCI
domains, we don't support those versions anymore (see
4a42ece13a). Therefore it is safe to always format fully
expanded PCI address. Format PCI domain always as it will
simplify next commits.

a08c4b3741 qemu: Always assume QEMU_CAPS_REALTIME_MLOCK
The '-realtime mlock' cmd line argument was introduced in QEMU
commit v1.5.0-rc0~190 which matches minimal QEMU version we
require. Therefore, the capability will always be present.

Apparently, nearly none of our xml2argv test cases had the
capability hence slightly bigger change under qemuxml2argvdata/.

75a9169881 qemu: command: Override HOME variable for system QEMU
By default, qemu user's home dir points to '/' which shouldn't be used
at all. We therefore pass the HOME variable from the current variable
iff not running as SUID, which means that for systemd we never set it.
This patch makes sure, that for system QEMU this is always set to
libDir/<driver>, session mode is left untouched.

7e73137495 qemu: command: Enforce setting XDG variables for system QEMU
For session mode, only XDG_CACHE_HOME is set, because we want to remain
integrating with services in user session, but for system mode, this
would have become reading/writing to '/' which carries the obvious issue
with permissions (also, '/' is the wrong location in 99.9% cases anyway).

1dcba456fa qemu: caps: Always assume presence of 'ide-hd' and 'ide-cd' devices
The split of ide-disk into the two separate devices was introduced by
qemu commit 1f56e32a7f4b3 released in qemu v0.15.

Note that when compared to the previous commit which made sure that no
disk related tests were touched, in this case it's not as careful.

7ea7342996 conf: correct false boot order error during domain parse
virDomainDefCollectBootOrder() is called for every item on the list
for each type of device. One of the checks it makes is to gather the
order attributes from the <boot> element of all devices, and assure
that no two devices have been given the same order.

Since (internally to libvirt, *not* in the domain XML) an <interface
type='hostdev'> is on both the list of hostdev devices and the list of
network devices, it will be counted twice, and the code that checks
for multiple devices with the same boot order will give a false
positive.

To remedy this, we make sure to return early for hostdev devices that
have a parent.type != NONE.

This was introduced in commit 5b75a4, which was first in libvirt-4.4.0.
