This series makes the next step towards a QAPI interface that doesn't require
clients to know about BlockBackends. By removing the support for 'id' from
blockdev-add, it becomes a command that always only creates a BDS (with a node
name). Existing interfaces have already been changed to accept node names
everywhere and BlockBackends are created whenever they are needed.
The actual change is in the last patch and pretty trivial, but many test cases
use blockdev-add to create a BlockBackend and must be updated first.
Depends on:
* [PATCH 00/10] block: Accept qdev IDs in device level QMP commands
* [PATCH] block: Allow node name for 'qemu-io' HMP command

We want to remove the 'id' option for blockdev-add. This removes one
user of the option and makes it use only node names.
In order to keep the test meaningful, some instances of query-block that
want to check whether the node still exists and would now turn up empty
must be converted to query-named-block-nodes (which also return the
protocol level node, but that shouldn't hurt).

We want to remove the 'id' option for blockdev-add. This removes one
user of the option and makes it use only node names.

We want to remove the 'id' option for blockdev-add. This removes one
user of the option and makes it use only node names.
The test cases that test conflicts between the 'id' option to
blockdev-add and existing block devices or the 'node-name' of the same
command can be removed because it won't be possible to specify this at
the end of the series.

To: qemu-block; +Cc: kwolf, qemu-devel
We want to remove the 'id' option for blockdev-add. This removes one
user of the option and makes it use only node names.

To: qemu-block; +Cc: kwolf, qemu-devel
With this patch, blockdev-add always works on a node level, i.e. it
creates a BDS, but no BB. Consequently, x-blockdev-del doesn't need the
'device' option any more, but 'node-name' becomes mandatory.
