Peter Krempa eae59247c5 qemu: Update state of block job to READY only if it actually is ready
Few parts of the code looked at the current progress of and assumed that
a two phase blockjob is in the _READY state as soon as the progress
reached 100% (info.cur == info.end). In current versions of qemu this
assumption is invalid and qemu exposes a new flag 'ready' in the
query-block-jobs output that is set to true if the job is actually
finished.

This patch adds internal data handling for reading the 'ready' flag and
acting appropriately as long as the flag is present.

While this still doesn't fix the virsh client problem with two phase
block jobs and the --pivot option, it at least improves the error
message:

$ virsh blockcommit  --wait --verbose vm vda  --base vda[1] --active --pivot
Block commit: [100 %]error: failed to pivot job for disk vda
error: internal error: unable to execute QEMU command 'block-job-complete': The active block job for device 'drive-virtio-disk0' cannot be completed

to

$ virsh blockcommit  --wait --verbose VM vda  --base vda[1] --active --pivot
Block commit: [100 %]error: failed to pivot job for disk vda
error: block copy still active: disk 'vda' not ready for pivot yet

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
