When running dtc on the guest /proc/device-tree we get the
following warning: Warning (unit_address_vs_reg): Node /memory
has a reg or ranges property, but no unit name".
Let's fix that by adding the unit address to the node name. We also
don't create the /memory node anymore in create_fdt(). We directly
create it in load_dtb. /chosen still needs to be created in create_fdt
as the uart needs it. In case the user provided his own dtb, we nop
all memory nodes found in root and create new one(s).

Nodes should have a name in the form <name>[@<unit-address>] where

We are gradually moving away from sector-based interfaces, towards
byte-based. Now that all callers of vectored I/O have been converted
to use our preferred byte-based bdrv_co_p{read,write}v(), we can
delete the unused bdrv_co_{read,write}v().
Furthermore, this gets rid of the signature difference between the
public bdrv_co_writev() and the callback .bdrv_co_writev (the
latter still exists, because some drivers still need more work
before they are fully byte-based).

We are gradually moving away from sector-based interfaces, towards

get_cluster_offset(), by changing n_start and n_end to be byte
offsets rather than sector indices within the cluster being
allocated. However, assert that these values are still
sector-aligned (at least qcrypto_block_encrypt() still wants that).
For now we get that alignment for free because we still use
sector-based driver callbacks.
A later patch will then switch the qcow driver as a whole over
to byte-based operation; but will still leave things at sector
alignments as it is not worth auditing the qcow image format
to worry about sub-sector requests.

Also, change the return value from -ENOSTUP to -ENOSPC when the actual
issue is request range passes EOF, which should be distinguishable from
the case of error == ENOSYS by the caller, so that it could still retry
with other byte ranges, whereas it shouldn't retry anymore upon ENOSYS.
