A few cleanups needed. I'll get to that right now.

Yes, this part is still in flux: there are a few more parameters that
are going to be passed (like the name for the port). Also, I'm planning
to add an API within qemu for data transfer over serial ports and a
key-value pair will be suitable for that. So that'll require a separate
parameter as well. This API will be useful to support migration better
and also qemu to converse with the guest.

So extending the -serial option is certainly possible but I've to make
sure the virtio serial-specific options don't apply to the others. I've
not gotten to look into that yet.
