QMP: add snapshot-blkdev-sync command
Add QMP bits for snapshot_blkdev command. This is the same as
snapshot_blkdev in the human monitor. The command is synchronous.
In the future async commands and or a break down of the functionality
into multiple commands might be added.
Also change the 'snapshot_file' argument to 'snapshot-file' in
the human monitor, so that it matches QMP.
