qmp: convert blockdev-snapshot-sync to a wrapper around transactions
Simplify the blockdev-snapshot-sync code and gain failsafe operation by turning it into a wrapper around the new transaction command. A new option is also added matching "mode". Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

# Returns: nothing on success

# If @format is invalid, InvalidBlockFormat
#
-# Notes: One of the last steps taken by this command is to close the current
-# image being used by @device and open the @snapshot-file one. If that
-# fails, the command will try to reopen the original image file. If
-# that also fails OpenFileFailed will be returned and the guest may get
-# unexpected errors.
