eb768a556d backup: Add support for passing server socket file descriptor to backup NBD server
In deployments where libvirt is containerized together with the VM it
may be hard for the management application to access listening sockets
inside the container from the outside.

This patch implements "transport='fd'" for the NBD server definition for
backups which allows to use the existing "virDomainFDAssociate()" to
pass FD to a pre-opened server socket to qemu instead of trying to
create it by qemu.

Add schema, enable the parser, add formatter and implement the actual
passing for the qemu backup code.

e3922af17c conf: backup: Format index of 'store'
Similarly to other disk-related stuff, the index is useful when you want
to refer to the image in APIs such as virDomainSetBlockThreshold.

For internal use we also need to parse it inside of the status XML.

7e5b993d3b backup: Allow configuring incremental backup per-disk individually
The semantics of the backup operation don't strictly require that all
disks being backed up are part of the same incremental part (when a disk
was checkpointed/backed up separately or in a different VM), or even
they may not have a previous checkpoint at all (e.g. when the disk
was freshly hotplugged to the vm).

In such cases we can still create a common checkpoint for all of them
and backup differences according to configuration.

This patch adds a per-disk configuration of the checkpoint to do the
incremental backup from via the 'incremental' attribute and allows
perform full backups via the 'backupmode' attribute.

Note that no changes to the qemu driver are necessary to take advantage
of this as we already obey the per-disk 'incremental' field.
