In commit 6111b23522 removing pre-blockdev code paths I've
improperly refactored the setup of non-shared storage migration.
Specifically the code checking that there are disks and setting up the
NBD data in the migration cookie was originally outside of the loop
checking the user provided list of specific disks to migrate, but became
part of the block as it was not un-indented when a higher level block
was being removed.
The above caused that if non-shared storage migration is requested, but
the user doesn't provide the list of disks to migrate (thus implying to
migrate every appropriate disk) the code doesn't actually setup the
migration and then later on falls back to the old-style migration which
no longer works with blockdev.
Move the check that there's anything to migrate out of the
'nmigrate_disks' block.

Adding supposedly secure cleanup for secrets in anything related to the
XML parser is pointless because there are multiple other un-sanitized
copies of the full XML and the XML parser state at the very least.
Similarly in case RPC was used to transport the XML the RPC buffers are
not sanitized.
Additionally this patch was incomplete as it didn't sanitize the
password in the cleanup function for virDomainGraphicsAuthDef.

This patch adds the generalized job object into the domain object
so that it can be used by all drivers without the need to extract
it from the private data.
Because of this, the job object needs to be created and set
during the creation of the domain object. This patch also extends
xmlopt with possible job config containing virDomainJobObj
callbacks, its private data callbacks and one variable
(maxQueuedJobs).
This patch includes:
* addition of virDomainJobObj into virDomainObj (used in the
following patches)
* extending xmlopt with job config structure
* new function for freeing the virDomainJobObj

We have always considered "migrate_cancel" QMP command to return after
successfully cancelling the migration. But this is no longer true (to be
honest I'm not sure it ever was) as it just changes the migration state
to "cancelling". In most cases the migration is canceled pretty quickly
and we don't really notice anything, but sometimes it takes so long we
even get to clearing migration capabilities before the migration is
actually canceled, which fails as capabilities can only be changed when
no migration is running. So to avoid this issue, we can wait for the
migration to be really canceled after sending migrate_cancel. The only
place where we don't need synchronous behavior is when we're cancelling
migration on user's request while it is actively watched by another
thread.
