eucalyptus should support booting multiboot image

@Scott, Can you clarify that the proposed fix for now is to:
Make a floppy containing a pv-grub bootloader?

If this is the case, can you confirm that it shouldn't regress images not containing a floppy?

Thanks

The intent is to not regress existing images.
The protection against doing so is:
if (kernel file looks like a linux kernel) or (virtio root); then
  use old path
else
  load the aki payload via multiboot from a floppy
fi

I would like to change that to be:
if (kernel file is a multiboot compliant image) and (!virtio root); then
  load the aki payload via multiboot from a floppy
else
  use old path
fi

The problem right now is that I do not have a good check for "is a multiboot compliant image".
Updates can be made to the "is_multiboot_img" subroutine of gen_kvm_libvirt_xml

  * New upstream merge, r1218
  * debian/eucalyptus.conf:
    - Changed JVM_MEM to CLOUD_OPTS, as a standardised method.
    - Introduced new stub SC, adding ability to disable EBS and ISCSI.
    - Added to CC stub ability to disable tunnelling in multi-cluster deployments.
    - In NC section added various VIRTIO options with sane defaults.
    - Added hints for changing the resource allocation, making limiting and over
      provisioning easier to identify. (MAX_MEM, MAX_CORES & MAX_DISK).
