[Qemu-block] [PATCH 0/7] Make qemu-img/qemu-nbd/qemu-io CLI more flexible

[Daniel P. Berrange]

This series of patches expands the syntax of the qemu-img,
qemu-nbd and qemu-io commands to make them more flexible.

First all three gain a --object parameter, which allows
instantiation of user creatable object types. The immediate
use case is to allow for creation of the 'secret' object
type to pass passwords for curl, iscsi and rbd drivers.
For qemu-nbd this will also be needed to create TLS
certificates for encryption support.

Then all three gain a '--source' parameter which exposes
the full set of block backend parameters in a single arg.
This obsoletes the current approach where the filename is
specified as a positional arg and then custom CLI args need
to be created for each block parameter, eg obsoletes need
for things like '-f format'. Again the immediate use case
is to allow the user to specify the ID of the 'secret' object
then just created.

These patches were previousl sent as part of a larger
series here:

  http://lists.gnu.org/archive/html/qemu-devel/2015-10/msg04365.html

I split them off, since some parts of that series are merged,
and this set of patches is fairly independant of the rest,
so doesn't need to gate on them
