Currently we get capability like info in the following areas:

 * List of CPUs:

            $QEMU -cpu ?

 * List of machine types:

            $QEMU -M ?

 * List of devices & properties:

            $QEMU -device ? \
                  -device pci-assign,? \
                  -device virtio-blk-pci,? \
                  -device virtio-net-pci,? \
                  -device scsi-disk,?

As well as 80 odd other pieces of information[1] via -help, but lets not
get side tracked by those right now. What is proposed so far is a good
start, we can iteratively build on.

If we can get the above commands into JSON format too, that'd be nice
so that we can have one parser to rule them all.

Daniel
