since qemu 6.0, if migration is blocked for some reason, 'query-migrate'
will return an array of error strings describing the migration blockers.
This can be used to check whether there are any devices blocking
migration, etc.

We will need two attributes of usb-host device to set:
guest-reset and guest-resets-all. The former was introduced in
QEMU v4.0.0-rc0~56^2 and the other in v4.2.0-rc1~9^2. Hence,
track the latter only as it's only starting from that commit when
QEMU has both attributes.

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.

This capability reflects whether QEMU allows setting
thread-pool-min and thread-pool-max attributes on iothread
object. Since both attributes were introduced in the same commit
(v7.0.0-878-g71ad4713cc) and can't exist independently of each
other we can stick with one capability covering both of them.

The prealloc-threads is property of memory-backend class which is
parent to the other three classes memory-backend-{ram,file,memfd}.
Therefore the property is present for all, or none if QEMU is
older than v5.0.0-rc0~75^2~1^2~3 which introduced the property.
Anyway, the .reserve property is the same story, and we chose
memory-backend-file to detect it, so stick with our earlier
decision and use the same backend to detect this new property.
