##
# @guest-sync:
#
# Echo back a unique integer value
#
# This is used by clients talking to the guest agent over the
# wire to ensure the stream is in sync and doesn't contain stale
# data from previous client. All guest agent responses should be
# ignored until the provided unique integer value is returned,
# and it is up to the client to handle stale whole or
# partially-delivered JSON text in such a way that this response
# can be obtained.
#
# Such clients should also precede this command
# with a 0xFF byte to make such the guest agent flushes any
# partially read JSON data from a previous session.
#
# @id: randomly generated 64-bit integer
#
# Returns: The unique integer id passed in by the client
