In case an async job spans multiple APIs (e.g., incoming migration) the
API that started the job is recorded as the asyncOwnerAPI even though it
is no longer running and the owner thread is updated properly to the one
currently handling the job. Let's also update asyncOwnerAPI to make it
more obvious which is the current (or the most recent) API involved in
the job.

Calling prlimit() requires elevated privileges, specifically
CAP_SYS_RESOURCE, and getrlimit() only works for the current
process which is too limiting for our needs; /proc/$pid/limits,
on the other hand, can be read by any process, so implement
parsing that file as a fallback for when prlimit() fails.
This is useful in containerized environments.

When the backup job is terminated normally the security label is
restored by the blockjob finishing handler.
If the VM dies or is destroyed that wouldn't happen as the blockjob
handler wouldn't be called.
Restore the security label on disk store where we remember that the job
was running at the point when 'qemuBackupJobTerminate' was called.
Not resetting the security label means that we also leak the xattr
attributes remembering the label which prevents any further use of the
file, which is a problem for block devices.
This also requires that the call to 'qemuBackupJobTerminate' from
'qemuProcessStop' happens only after 'vm->pid' was reset as otherwise
the security subdrivers attempt to enter the process namespace which
fails if the process isn't running any more.

This is because the initial population of the device list is done in a
separate initialization thread. If we attempt to exit libvirtd before
this init thread has completed, we'll try to free the device list while
accessing it from the other thread. In order to guarantee that this
init thread is not accessing the device list when we're cleaning up the
nodedev driver, make it joinable and wait for it to finish before
proceding with the cleanup. This is similar to how we handle the udev
event handler thread.
The separate initialization thread was added in commit
9f0ae0b1.
