Currently, we require glib-2.56.0 at minimum (because of RHEL-8)
but we use G_GNUC_NO_INLINE which was introduced in 2.58.0. While
we provide an implementation for older versions, where the macro
does not exists, it's a bit more tricky than that. Since we
define GLIB_VERSION_MAX_ALLOWED we would get a compile time error
when trying to use something too new, except for G_GNUC_NO_INLINE
which was intentionally not marked as
GLIB_AVAILABLE_MACRO_IN_2_58. But this is about to change with
glib-2.73.2 (which contains commit [1]).
At the same time, we can't just bump glib and thus we have to
provide an alternative implementation without the version
annotation.

QEMU offers two attributes for handling reset requests of an USB
host device: guest-reset and guest-resets-all. When combined they
act as follows:
1) guest-reset=false
The guest is not allowed to reset the physical USB device.
2) guest-reset=true,guest-resets-all=false
The guest is allowed to reset the device when it is not yet
initialized (aka no USB bus address assigned). Usually this results
in one guest reset being allowed. This is the default behavior.
3) guest-reset=true,guest-resets-all=true
The guest is allowed to reset the device as it pleases.
Now, there's a clear 1:1 mapping with our representation of
guestReset, so generating cmd line is trivial.

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

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).
