This patch adds a new machine type, virt-rhel8.1.0, for QEMU rhel-av.
This machine type is based off 4.0 with the exception that it removes
support for dynamic sysbus devices: VFIO_CALXEDA_XGMAC, VFIO_AMD_XGBE, and
RAMFB_DEVICE because downstream RHEL doesn't support these devices. IOMMU
instantiation still is disabled but will be enabled in subsequent patches.

This patch restores the ARM VIRT iommu option historically
introduced in qemu 3.0 and disabled in rhel8.0 (RHBZ#1656504 /
commit 7bfdb4cd2b49) as we did not have support of the feature
at libvirt level.

Seems some devices become confused when we call
libusb_set_configuration(). So before calling the function check
whenever the device has multiple configurations in the first place, and
in case it hasn't (which is the case for the majority of devices) simply
skip the call as it will have no effect anyway.

If the guest didn't talk to the device yet, skip the reset.
Without this usb-host devices get resetted a number of times
at boot time for no good reason.

Objects should not be "delayed" without a reason, as the previous
commit demonstrates. The remaining ones have reasons. State them.
and demand future ones come with such a statement.

qemu-system-FOO's main() acts on command line arguments in its own
idiosyncratic order. There's not much method to its madness.
Whenever we find a case where one kind of command line argument needs
to refer to something created for another kind later, we rejigger the
order.
Recent commit cda4aa9a5a "vl: Create block backends before setting
machine properties" was such a rejigger. Block backends are now
created before "delayed" objects. This broke persistent reservation
management. Reproducer:
$ qemu-system-x86_64 -object pr-manager-helper,id=pr-helper0,path=/tmp/pr-helper0.sock-drive -drive file=/dev/mapper/crypt,file.pr-manager=pr-helper0,format=raw,if=none,id=drive-scsi0-0-0-2
qemu-system-x86_64: -drive file=/dev/mapper/crypt,file.pr-manager=pr-helper0,format=raw,if=none,id=drive-scsi0-0-0-2: No persistent reservation manager with id 'pr-helper0'
The delayed pr-manager-helper object is created too late for use by
-drive or -blockdev. Normal objects are still created in time.
pr-manager-helper has always been a delayed object (commit 7c9e527659
"scsi, file-posix: add support for persistent reservation
management"). Turns out there's no real reason for that. Make it a
normal object.
