QEMU allows us to create storage on certain network protocols which
allow image creation through their API. Wire up the generator for using
it with libvirt as well as for local files.

'blockdev-add' allows us to use qemu to format images to our desired

To allow using -blockdev with blockjobs QEMU needs to reopen files in
read-write mode when modifying the backing chain. To achieve this we
need to use 'auto-read-only' for the backing files rather than the
normal 'read-only' property. That way qemu knows that the files need to
be reopened.

Note that the format drivers (e.g. qcow2) are still opened with the
read-only property enabled when being a member of the backing chain
since they are supposed to be immutable unless a block job is started.

QEMU v4.0 (since commit 23dece19da4) allows also dynamic behaviour for
auto-read-only which allows us to use sVirt as we only grant write
permissions to files when doing a blockjob.

To allow reusing the formatters in the code for creating JSON properties
for 'blockdev-create' we need to create everything except the 'driver'
attribute.

Use the new helper virJSONValueObjectPrependString to put the driver at

Libvirt treats the JSON objects as lists thus the values appear in the

virCommandMassCloseGetFDsLinux fails when running libvird on valgrind
with the following message:

libvirt:  error : internal error: unable to set FD as open: 1024

This is because valgrind opens few file descriptors beyond the limit:
