Some USB devices have a buggy firmware that either crashes on
device reset, or make the device unusable in some other way.
Fortunately, QEMU offers a way to skip device reset either
completely, or if device is not initialized yet. Expose this
ability to users under:
<hostdev mode='subsystem' type='usb'>
<source guestReset='off'/>
</hostdev>

My commit of v6.9.0-rc1~457 was a bit too harsh. While it served
its purpose (adding usb-host.hostdevice capability) it has a side
effect: because I copied reply from qemu-5.1.0 to older .replies
files one might now think that say qemu-3.1.0 supports both
.guest-reset and .guest-resets-all properties. But in fact it
doesn't. There are three problematic properties:
1) guest-reset, introduced in v4.0.0-rc0~56^2
2) guest-resets-all introduced in v4.2.0-rc1~9^2
3) suppress-remote-wake introduced in v5.0.0-rc0~148^2~4
Remove these properties from versions that could not have had
them.

Our man page already documents that iothreadset has --config

There are three APIs that allow changing IOThreads:
virDomainAddIOThread()
virDomainDelIOThread()
virDomainSetIOThreadParams()
In case of QEMU driver these are handled by
qemuDomainChgIOThread() which attempts to be versatile enough to
work on both inactive and live domain definitions at the same
time. However, it's a bit clumsy - when a change to live
definition succeeds but fails in inactive definition then there's
no rollback. And somewhat rightfully so - changes to live
definition are in general harder to roll back. Therefore, do what
we do elsewhere (qemuDomainAttachDeviceLiveAndConfig(),
qemuDomainDetachDeviceAliasLiveAndConfig(), ...):
1) do the change to inactive XML first,
2) in fact, do the change to a copy of inactive XML,
3) swap inactive XML and its copy only after everything
succeeded.

When formatting IOThreads (in virDomainDefIOThreadsFormat()), we
may only output the number of IOThreads, or the full list of IOThreads too:
<iothreads>4</iothreads>
<iothreadids>
<iothread id='1' thread_pool_max='10'/>
<iothread id='2' thread_pool_min='2' thread_pool_max='10'/>
<iothread id='3'/>
<iothread id='4'/>
</iothreadids>
Now, the deciding factor here is whether those individual
IOThreads were so called 'autofill-ed' or user provided. Well, we
need to take another factor in: if an IOThread has pool size
limit set, then we ought to format the full list.
But how can we get into a situation when a thread is autofilled
(i.e. not provided by user in the XML) and yet it has pool size
limit set? virDomainSetIOThreadParams() is the answer.
Sure, we could also unset the autofill flag whenever a pool size
limit is being set. But this approach allows us to not format
anything if the limits are reset (we don't lose the autofill
information).

When virDomainSetIOThreadParams() API is called, well its QEMU
impl: qemuDomainSetIOThreadParams() then typed params are parsed
by qemuDomainIOThreadParseParams() into this
qemuMonitorIOThreadInfo struct. In the struct we have a <int,
bool> pair for every IOThread attribute we can tune through
monitor. The struct is then passed to
qemuMonitorJSONSetIOThread() which looks at the bool and if set
then the corresponding attribute is set to given value. Each
attribute is thus changed in a separate call. While this works
for attributes independent of each other ("poll-max-ns",
"poll-grow", "poll-shrink"), it does not always work for the
other attributes ("thread-pool-min" and "thread-pool-max").
The limitation here is that the lower boundary (minimum) has to
be lower (or equal to) the upper boundary (maximum) at all times.
This means, that in some cases we might need to set attributes in
reversed order to meet the constraint.
