When removing a socket in virCHMonitorClose() fails, a warning is
printed. But it doesn't contain errno nor g_strerror() which may
shed more light into why removing of the socket failed.
Oh, and since virCHMonitorClose() is registered as autoptr
cleanup for virCHMonitor() it may happen that virCHMonitorClose()
is called with mon->socketpath allocated but file not existing
yet (see virCHMonitorNew()). Thus ignore ENOENT and do not print
warning in that case - the file doesn't exist anyways.

The virCHMonitorClose() is meant to be called when monitor to
cloud-hypervisor process closes. It removes the socket and frees
string containing path to the socket.
In general, there is a problem with the following pattern:
if (var) {
do_something();
g_free(var);
}
because if the pattern executes twice the variable is freed
twice. That's why we have VIR_FREE() macro. Well, replace plain
g_free() with g_clear_pointer(). Mind you, this is NOT a
destructor where clearing pointers is needless.

Let me preface this with stating the obvious: documentation on
QoS in OVS is very sparse. This is all based on my observation
and OVS codebase analysis.
For the following QoS setting:
<bandwidth>
<inbound average="512" peak="1024" burst="32"/>
</bandwidth>
the following QoS setting is generated into OVS (NB, our XML
values are in KiB/s, OVS has them in bits/s):
# ovs-vsctl list qos
_uuid : a087226b-2da6-4575-ad4c-bf570cb812a9
external_ids : {ifname=vnet1, vm-id="7714e6b5-4885-4140-bc59-2f77cc99b3b5"}
other_config : {burst="262144", max-rate="8192000", min-rate="4096000"}
queues : {0=655bf3a7-e530-4516-9caf-ec9555dfbd4c}
type : linux-htb
from which the following topology is generated:
# for i in qdisc class; do tc -s -d -g $i show dev vnet1; done
qdisc htb 1: root refcnt 2 r2q 10 default 0x1 direct_packets_stat 0 ver 3.17 direct_qlen 1000

backlog 0b 0p requeues 0
Long story short, the default class (1:) for an OVS interface has
average and peak set exactly as requested. But since it's nested
under another class (1:fffe), it can borrow unused bandwidth. And
the parent is set to have rate = ceil = peak from our XML. From
[1]: htb_tc_install() calls htb_parse_qdisc_details__() which
sets: 'hc->min_rate = hc->max_rate;' and then calls
htb_setup_class_(..., tc_make_handle(1, 0xfffe), tc_make_handle(1, 0), &hc);
to set up the top parent class.
In other words - the interface is set up to so that it can always
consume 'peak' bandwidth and there is no way for us to set it up
differently. It's too late to deny setting 'peak' different to
'average' at XML validation phase so do the next best thing -
throw a warning, just like we do in case <bandwidth/> is set for
an unsupported <interface/> type.

Add reporting of panic device models into the domain capabilities based
on the logic in qemuValidateDomainDefPanic() and also report whether
panic devices are supported based on whether at least one model is
supported. That way consumers of the domain capability XML can
differentiate between libvirt not reporting the panic device models or
