Dr. David Alan Gilbert c6644548c7 net/announce: Add HMP optional ID 
Add the optional ID to the HMP command.

e.g.
   # start an announce for a long time on eth1
   migrate_set_parameter announce-rounds 1000
   announce_self "eth1" e1

   # start an announce on eth2
   announce_self "eth2" e2

   # Change e1 to be announcing on eth1 and eth3
   announce_self "eth1,eth3" e1

   # Cancel e1
   migrate_set_parameter announce-rounds 0
   announce_self "" e1

STEXI
@item commit
@findex commit
Commit changes to the disk images (if -snapshot is used) or backing files.
If the backing file is smaller than the snapshot, then the backing file will be
resized to be the same size as the snapshot. If the snapshot is smaller than
the backing file, the backing file will not be truncated. If you want the
backing file to match the size of the smaller snapshot, you can safely truncate
it yourself once the commit operation successfully completes.

@item exit_preconfig
@findex exit_preconfig
This command makes QEMU exit the preconfig state and proceed with
VM initialization using configuration data provided on the command line
and via the QMP monitor during the preconfig state. The command is only
available during the preconfig state (i.e. when the --preconfig command
line option was in use).

STEXI
@item block_resize
@findex block_resize
Resize a block image while a guest is running. Usually requires guest
action to see the updated size. Resize to a lower size is supported,
but should be used with extreme caution. Note that this command only
resizes image files, it can not resize block devices like LVM volumes.

.help = "remove host block device",

},
STEXI
@item drive_del @var{device}
@findex drive_del
Remove host block device. The result is that guest generated IO is no longer
submitted against the host device underlying the disk. Once a drive has
been deleted, the QEMU Block layer returns -EIO which results in IO
errors in the guest for applications that are reading/writing to the device.
These errors are always reported to the guest, regardless of the drive's error
actions (drive options rerror, werror).

@table @option
@item change @var{diskdevice} @var{filename} [@var{format} [@var{read-only-mode}]]
Change the medium for a removable disk device to point to @var{filename}. eg
@example
(qemu) change ide1-cd0 /path/to/some.iso
@end example
@var{format} is optional.
@var{read-only-mode} may be used to change the read-only status of the device.
It accepts the following values:
@table @var
@item retain
Retains the current status; this is the default.
@item read-only
Makes the device read-only.
@item read-write
Makes the device writable.
@end table
@item change vnc @var{display},@var{options}
Change the configuration of the VNC server. The valid syntax for @var{display}
and @var{options} are described at @ref{sec_invocation}. eg
@example
(qemu) change vnc localhost:1
@end example
@item change vnc password [@var{password}]
Change the password associated with the VNC server. If the new password is not
supplied, the monitor will prompt for it to be entered. VNC passwords are only
significant up to 8 letters. eg
@example
(qemu) change vnc password
Password: ********

Stop exporting a block device through QEMU's NBD server, which was
previously started with @command{nbd_server_add}. The @option{-f}
option forces the server to drop the export immediately even if
clients are connected; otherwise the command fails unless there are no
