Commit 88957116c9 switched to use
memory-backend-* for regular VM memory as well. That change indirectly
started using 'host-nodes' for system memory which results in QEMU
calling mbind() to bind the system memory to specific NUMA node if the
VM XML contains the configuration similar to this:
...
<numatune>
<memory mode='strict' nodeset='0'/>
</numatune>
...
Once the VM was started with that configuration it was no longer
possible to change the memory NUMA nodeset.

openssh supports environment variable expansion in its ssh_config
file[1]. These two environment variables can be used to
expand paths for ssh sockets and other files.
Ex.
```
Host *
ControlMaster auto
ControlPath ${XDG_RUNTIME_DIR}/ssh-%C.ctl
IdentityAgent ${XDG_RUNTIME_DIR}/ssh-agent.socket
```

If there is no tcp_min_ssf value set in daemon config we still
compare it against the default (56 which corresponds to DES) and
if the value is below our expected minimum (112 which corresponds
to 3DES) an error is reported and the daemon refuses to start.
This is not what we want. What we want is to check the value iff
the value was specified in the config file.

Extend the TPM backend XML with a node 'active_pcr_banks' that allows a
user to specify the PCR banks to activate before starting a VM. Valid
choices for PCR banks are sha1, sha256, sha384 and sha512. When the XML
node is provided, the set of active PCR banks is 'enforced' by running
swtpm_setup before every start of the VM. The activation requires that
swtpm_setup v0.7 or later is installed and may not have any effect
otherwise.

At this point, we're no longer using the availability of the
ZFS programs at build time to decide whether to enable ZFS
support, so the only purpose of these find_program() calls is
to record their absolute paths.
However, the virCommand facilities that we're ultimately using
to run them are already capable of performing this lookup at
runtime, and in fact that's exactly what we already do in the
case of, for example, vstorage.
Drop the build time lookups and always perform them at runtime.

Commit 73a2ff3616 already improved the situation a lot. This
pushes things even further.
If the user or, more likely, the distro packager explicitly
asked for ZFS support to be enabled, then we should comply with
that request regardless of whether the necessary programs are
available at build time.
This is particularly important in the context of Debian, where
ZFS cannot be a build dependency of libvirt due to licensing
issues but it can still be an optional runtime dependency.
