Replace
error_report("DEVICE-NAME: MESSAGE");
by just
error_report("MESSAGE");
in block device init functions.
DEVICE-NAME is bogus in some cases: it's "scsi-disk" for device
scsi-hd and scsi-cd, "virtio-blk-pci" for virtio-blk-s390, and
"usb-msd" for usb-storage.
There is no real need to put a device name in the message, because
error_report() points to the offending command line option already:
$ qemu-system-x86_64 --nodefaults --enable-kvm -vnc :0 -S -monitor stdio -usb -device virtio-blk-pci
upstream-qemu: -device virtio-blk-pci: virtio-blk-pci: drive property not set
upstream-qemu: -device virtio-blk-pci: Device 'virtio-blk-pci' could not be initialized
And for a monitor command, it's obvious anyway:
$ qemu-system-x86_64 --nodefaults --enable-kvm -vnc :0 -S -monitor stdio -usb
(qemu) device_add virtio-blk-pci
virtio-blk-pci: drive property not set
Device 'virtio-blk-pci' could not be initialized

Remove the default compiled out tunnel channel, add the always available

When configuring the prefetch engine (and also when resetting from
a state where the prefetch engine was enabled) be careful to adhere
to the "unmap/change config fields/map" ordering, to avoid trying
to delete the wrong MemoryRegions. This fixes an assertion failure

We no longer use any of the lower bits of a ram_addr, so we might as well
use them for the io table index. This increases the number of potential

backend_registered was used to lazify the process of registering an
mmio region, since the it is different for the I/O address space and
the memory address space. However, it also makes registration dependent
on the region being visible in the address space. This is not the case
for "fake" regions, like watchpoints or IO_MEM_UNASSIGNED.
Remove backend_registered and always initialize the region. If it turns
out to be part of the I/O address space, we've wasted an I/O slot, but
that's not too bad. In any case this will be optimized later on.

Version 3 ram_load depends on ram_addrs, which are not stable. Version 4

Currently creating a memory region automatically registers it for
live migration. This differs from other state (which is enumerated
in a VMStateDescription structure) and ties the live migration code
into the memory core.
Decouple the two by introducing a separate API, vmstate_register_ram(),
for registering a RAM block for migration. Currently the same
implementation is reused, but later it can be moved into a separate list,
and registrations can be moved to VMStateDescription blocks.
