IMPORTANT: this BREAKS QMP's compatibility for the error response.
This commit changes QMP's wire protocol to make use of the simpler
error format introduced by previous commits.
There are two important (and mostly incompatible) changes:
1. Almost all error classes have been replaced by GenericError. The
only classes that are still supported for compatibility with
libvirt are: CommandNotFound, DeviceNotActive, KVMMissingCap,
DeviceNotFound and MigrationExpected
2. The 'data' field of the error dictionary is gone
As an example, an error response like:
{ "error": { "class": "DeviceNotRemovable",
"data": { "device": "virtio0" },
"desc": "Device 'virtio0' is not removable" } }
Will now be emitted as:
{ "error": { "class": "GenericError",
"desc": "Device 'virtio0' is not removable" } }

This is not a full QAPI conversion, but an intermediate step.
In essence, do_netdev_add() is split into three functions:
1. netdev_add(): performs the actual work. This function is fully
converted to Error (thus, it's "qapi-friendly")
2. qmp_netdev_add(): the QMP front-end for netdev_add(). This is
coded by hand and not auto-generated (gen=no in the schema). The
reason for this it's a lot easier and simpler to with QemuOpts
this way
3. hmp_netdev_add(): HMP front-end.

The block streaming and job commands used '_' instead of '-' for reasons
of compatibility with libvirt, which already included support for the
'_' naming. However, the semantics of block_job_cancel have changed and
libvirt now needs to handle the new semantics.
Since the old semantics were never in a QEMU release we can still rename
the commands to use '-' instead of '_'. Libvirt is also happy because
the new name can be used to distinguish QEMU binaries that support the
latest block-job-cancel semantics from those that include a downstream
block_job_cancel command.
Therefore, let's apply the QAPI/QMP naming rules to the block streaming
and job commands. QEMU 1.1 will be the first release with these
commands so no upstream users can break.
Note that HMP commands are left with '_' because that is the convention
there.

The migrate command is one of those commands where HMP and QMP completely
mix up together. This made the conversion to the QAPI (which separates the
command into QMP and HMP parts) a bit difficult.
The first important change to be noticed is that this commit completes the
removal of the Monitor object from migration code, started by the previous
commit.
Another important and tricky change is about supporting the non-detached
mode. That is, if the user doesn't pass '-d' the migrate command will lock
the monitor and will only release it when migration is finished.
To support this in the new HMP command (hmp_migrate()), it is necessary
to create a timer which runs every second and checks if the migration is
still active. If it is, the timer callback will re-schedule itself to run
one second in the future. If the migration has already finished, the
monitor lock is released and the user can use it normally.
All these changes should be transparent to the user.

Unfortunately, this conversion required an additional change.
In the old QMP command, the 'snapshot-file' argument is specified as
optional. The idea is to take the snapshot internally if 'snapshot-file'
is not passed. However, internal snapshots are not supported yet so
the command returns a MissingParamater error if 'snapshot-file' is not
passed. Which makes the argument actually required and will cause
compatibility breakage if we change that in the future.
To fix this the QAPI converted blockdev_snapshot_sync command makes the
'snapshot-file' argument required. Again, in practice it's actually required,
so this is not incompatible.
If we do implement internal snapshots someday, we'll need a new argument
for it.

There are three important remarks in relation to the non-qapi command:
1. This commit also fixes the behavior of the 'query-vnc' and 'info vnc'
commands to return an error when qemu is built without VNC support
(ie. --disable-vnc). The non-qapi command would return the OK
response in QMP and no response in HMP
2. The qapi version explicitly marks the fields 'host', 'family',
'service' and 'auth' as optional. Their are not documented as optional
in the non-qapi command doc, but they would not be returned if
vnc support is disabled. The qapi version maintains the same
semantics, but documents those fields correctly
3. The 'clients' field, which is a list, is marked as optional but is
always returned. If there are no clients connected an empty list
is returned. This is not the Right Way to this in the qapi but it's
how the non-qapi command used to work

Allow client connections for VNC and socket based character
devices to be passed in over the monitor using SCM_RIGHTS.
One intended usage scenario is to start QEMU with VNC on a
UNIX domain socket. An unprivileged user which cannot access
the UNIX domain socket, can then connect to QEMU's VNC server
by passing an open FD to libvirt, which passes it onto QEMU.

{ "return": {} }
{ "execute": "add_client", "arguments": { "protocol": "vnc",

"skipauth": true } }
{ "return": {} }
In this case 'protocol' can be 'vnc' or 'spice', or the name
of a character device (eg from -chardev id=XXXX)
The 'skipauth' parameter can be used to skip any configured
VNC authentication scheme, which is useful if the mgmt layer
talking to the monitor has already authenticated the client
in another way.

query-block's specification documents response member "type" with
values "hd", "cdrom", "floppy", "unknown".
Its value is unreliable: a block device used as floppy has type
"floppy" if created with if=floppy, but type "hd" if created with
if=none.
That's because with if=none, the type is at best a declaration of
intent: the drive can be connected to any guest device. Its type is
really the guest device's business. Reporting it here is wrong.
No known user of QMP uses "type". It's unlikely that any unknown
users exist, because its value is useless unless you know how the
block device was created. But then you also know the true value.
Fixing the broken value risks breaking (hypothetical!) clients that
somehow rely on the current behavior. Not fixing the value risks
breaking (hypothetical!) clients that rely on the value to be
accurate. Can't entirely avoid hypothetical lossage. Change the
value to be always "unknown".
This makes "info block" always report "type=unknown". Pointless.
