The libvirt_recover_xattrs.sh tool hangs when run. When no flags
are provided OPTIND is 1, so the loop expands to 'shift 0' which
has not effect. Rewrite to just loop over $@ instead which involves
less cleverness.

In the dissect_xdr_bytes() there's a comment that the string
allocated by xdr_bytes() can't be freed using xdr_free(). Well,
that is expected because xdr_bytes() used plain calloc() AND the
string is not an XDR struct but plain 'char *' type. Passing it
to xdr_free() must result in weird things happening.

When the dissector sees a byte sequence that is either an opaque
data (xdr_opaque) or a byte sequence (xdr_bytes) it formats the
bytes as a hex numbers using our own implementation. But
wireshark already provides a function for it: tvb_bytes_to_str().
NB, the reason why it returns a const string is so that callers
don't try to free it - the string is allocated using an allocator
which will decide when to free it.
The wireshark formatter was introduced in wireshark commit of
v1.99.2~479 and thus is present in the version we require at
least (2.6.0).

Trying to connect once without a polkit agent will generate an error on the
server side which seems too rough given it only serves the purpose of the client
(virsh in this case) to figure out that an agent is needed. Thankfully we can
just try running the agent. It does not break anything as we are running it
with `--fallback`, which makes sure it does not replace an existing agent in
case there is one already registered.
The second piece of code trying to start the polkit text agent is kept in order
to _really_ try out starting the agent (and error out when failing to do so)
just in case the agent was not available the first time it was ran. Even though
it should not happen it avoids a very rare race condition and really does not
add much complexity.

In a few cases we call a public API, wrapped in an if() statement
with both branches written out explicitly. The error branch jumps
onto cleanup label, while the successful prints out a message.
Right after these ifs there's 'ret = true;' and the cleanup
label. The code is a bit more readable if only the error branch
is kept and printing happens at the same level as setting the ret
variable.

When you set metadata with type element like the following:

Then for `virsh event --all`, then it will output this message:
event 'metadata-change' for domain 'rhel9': element HAHAH
The message is ambiguous since it looks like the params for
metadata-change event is the element HAHAH. Actually that means the type is
element while the url is HAHAH. Let's make it more clear.

Issuing simple QMP commands is pain as they need to be wrapped by the
JSON wrapper:
{ "execute": "COMMAND" }
and optionally also:
{ "execute": "COMMAND", "arguments":...}
For simple commands without arguments we can add syntax sugar to virsh
which allows simple usage of QMP and additionally prepares also for
passing through of the 'arguments' section:
virsh qemu-monitor-command $VM query-status
is equivalent to
virsh qemu-monitor-command $VM '{"execute":"query-status"}'
and
virsh qemu-monitor-command $VM query-named-block-nodes '{"flat":true}'
or

As advertised in previous commit, this event is delivered to us
when virtio-mem module changes the allocation inside the guest.
It comes with one attribute - size - which holds the new size of
the virtio-mem (well, allocated size), in bytes.
Mind you, this is not necessarily the same number as 'requested
size'. It almost certainly will be when sizing the memory up, but
it might not be when sizing the memory down - the guest kernel
might be unable to free some blocks.
This current size is reported in the domain XML as an output
element only.
