Similarly to the disk source we need to keep the disk index (which is in
the qemu driver used for identification of the source for block jobs)
for the <mirror> element so that when it's replaced as a disk source
after pivoting all the allocated data is present.

When the block copy operation is started with a reused external file in
incremental mode libvirt will need to open and insert the backing chain
for that file into qemu (in -blockdev mode). This means that we'll need
to track the backing chain and metadata such as node names for the full
chain of <mirror>.

This patch invokes the full backing chain formatter and parser for
<mirror> so that the chain can be kept with <mirror>.

When adding <migrationSource> I've used a slightly unusual approach. To
allow using the disk source XML parser and formatter convert
<migrationSource> to look like <disk>. This means that <source> will be
added as a subelement of <migrationSource> rather than being formatted
inline.

Conversion from the old format in the parser is very simple as it
involves only moving the XPath context current node slightly if the new
format is found.

The status XML to XML test shows that the upgrade is done correctly.

Using copy_on_read for removable disks is a hassle. It also does not
work for CDROMs at all as the image is supposed to be read-only and we
might ignore it for floppies when they are started as empty. Forbid it

nobody is using.
