11c48fe6eb conf: convert VIR_FREE to g_free in other functions that free their arg
Previous patches have converted VIR_FREE to g_free in functions with
names ending in Free() and Dispose(), but there are a few similar
functions with names that don't fit that pattern, but server the same
purpose (and thus can survive the same conversion). in particular
*Free*(), and *Unref().

e5339e38ca esx: replace VIR_FREE with g_free in any ESX_VI__TEMPLATE__FREE
Invocations of the macro ESX_VI__TEMPLATE__FREE() will free the main
object (referenced as "item") that's pointing to all the things being
VIR_FREEd in the body, so it is safe for all the pointers in item to
just be g_freed rather that VIR_FREEd.

859f7e2072 qemu_shim: URI escape root directory
The root directory can be provided by user (or a temporary one is
generated) and is always formatted into connection URI for both
secret driver and QEMU driver, like this:

  qemu:///embed?root=$root

But if it so happens that there is an URI unfriendly character in
root directory or path to it (say a space) then invalid URI is
formatted which results in unexpected results. We can trust
g_dir_make_tmp() to generate valid URI but we can't trust user.
Escape user provided root directory. Always.

f28a652a32 ci: Makefile: Expose the CI_USER_LOGIN variable for users to use
More often than not I find myself debugging in the containers which
means that I need to have root inside, but without manually tweaking
the Makefile each time the execution would simply fail thanks to the
uid/gid mapping we do. What if we expose the CI_USER_LOGIN variable, so
that when needed, the root can be simply passed with this variable and
voila - you have a root shell inside the container with CWD=~root.

321293e2a3 ci: Drop the prepare.sh script
The purpose of this script was to prepare a customized environment in
the container, but was actually never used and it required the usage of
sudo to switch the environment from root's context to a regular user's
one.
The thing is that once someone needs a custom script they would very
likely to debug something and would also benefit from root privileges
in general, so the usage of 'sudo' in such case was a bit cumbersome.

ee07bffacc ci: Run podman command directly without wrapping it with prepare.sh
The prepare.sh script isn't currently used and forces us to make use
of sudo to switch the user inside the container from root to $USER
which created a problem on our Debian Slim-based containers which don't
have the 'sudo' package installed.
This patch removes the sudo invocation and instead runs the CMD
directly with podman.

Summary of the changes:
- move the corresponding env variables which we need to be set in the
  environment from the sudo invocation to the podman invocation
- pass --workdir to podman to retain the original behaviour we had with
  sudo spawning a login shell.
- MESON_OPTS env variable doesn't need to propagated to the execution
  environment anymore (like we had to do with sudo), because it's
  defined in the Dockerfile

c80911f2de src: define virDomainGetMessages API
This API allows fetching a list of informational messages recorded
against the domain. This provides a way to give information about
tainting of the guest due to undesirable actions/configs, as well
as provide details of deprecated features.

The output of this API is explicitly targetted at humans, not
machines, so it is inappropriate to attempt to pattern match on
the strings and take action off them, not least because the messages
are marked for translation.

Should there be a demand for machine targetted information, this
would have to be addressed via a new API, and is not planned at
this point in time.

db64acfbda conf: parse/format <teaming> element in plain <hostdev>
The <teaming> element in <interface> allows pairing two interfaces
together as a simple "failover bond" network device in a guest. One of
the devices is the "transient" interface - it will be preferred for
all network traffic when it is present, but may be removed when
necessary, in particular during migration, when traffic will instead
go through the other interface of the pair - the "persistent"
interface. As it happens, in the QEMU implementation of this teaming
pair (called "virtio failover" in QEMU) the transient interface is
always a host network device assigned to the guest using VFIO (aka
"hostdev"); the persistent interface is always an emulated virtio NIC.

When support was initially added for <teaming>, it was written to
require that the transient/hostdev device be defined using <interface
type='hostdev'>; this was done because the virtio failover
implementation in QEMU and the virtio guest driver demands that the
two interfaces in the pair have matching MAC addresses, and the only
way libvirt can guarantee the MAC address of a hostdev network device
is to use <interface type='hostdev'>, whose main purpose is to
configure the device's MAC address before handing the device to
QEMU. (note that <interface type='hostdev'> in turn requires that the
network device be an SRIOV VF (Virtual Function), as that is the only
type of network device whose MAC address we can set in a way that will
survive the device's driver init in the guest).

It has recently come up that some users are unable to use <teaming>
because they are running in a container environment where libvirt
doesn't have the necessary privileges or resources to set the VF's MAC
address (because setting the VF MAC is done via the same device's PF
(Physical Function), and the PF is not exposed to libvirt's container).

At the same time, these users *are* able to set the VF's MAC address
themselves in advance of staring up libvirt in the container. So they
could theoretically use the <teaming> feature if libvirt just skipped
the "setting the MAC address" part.

Fortunately, that is *exactly* the difference between <interface
type='hostdev'> (which must be a "hostdev VF") and <hostdev> (a "plain
hostdev" - it could be *any* PCI device; libvirt doesn't know what type
of PCI device it is, and doesn't care).

But what is still needed is for libvirt to provide a small bit of
information on the QEMU commandline argument for the hostdev, telling
QEMU that this device will be part of a team ("failover pair"), and
the id of the other device in the pair.

To make both of those goals simultaneously possible, this patch adds
support for the <teaming> element to plain <hostdev> - libvirt doesn't
try to set any MAC addresses, and QEMU gets the extra commandline
argument it needs)

(actually, this patch adds only the parsing/formatting of the
<teaming> element in <hostdev>. The next patch will actually wire that
into the qemu driver.)

7cf60006ce qemu: Fix swtpm device with aarch64
Starting a VM with swtpm device fails with qemu-system-aarch64.
E.g. with TPM device config

     <tpm model='tpm-tis'>
       <backend type='emulator' version='2.0'/>
      </tpm>

QEMU reports the following error

error: internal error: process exited while connecting to monitor:

tpm-tis,tpmdev=tpm-tpm0,id=tpm0: 'tpm-tis' is not a valid device model name

Indeed the TPM device name is 'tpm-tis-device' [1][2] for aarch64,
versus the shorter 'tpm-tis' for x86. The devices are the same from
a functional POV, i.e. they both emulate a TPM device conforming to
the TIS specification. Account for the unfortunate name difference
when building the TPM device option in qemuBuildTPMDevStr(). Also
include a test case for 'tpm-tis-device'.
