Disk creation improvements

Browse source 
* Support specifying the size of the target disk image for qemu
* For bare metal, only pad the image to the next megabyte
* Use truncate() to extend images, instead of writing zeros (faster)
* Return None from get_disk() with nonexistent name
* Leave 1MiB on non-boot disks, or 1GiB on boot disks, unpartitioned
  (for proper 4K alignment and to help preserve the srcfs or boot
  partition creation)
* Fix qemu invocation when an external.img is not used
* Make -qr work with kernel bootstrap (will need kexec-fiwix fix)
