[libvirt] [PATCH v2 RFC 0/4] qemu: replace nested job with interruptible async job state

[Nikolay Shirokovskiy]

This is the next version of RFC [1] 'drop nested job concept'. Actually
it is quite different from the first. Patches that accomodate callers to
use functions to enter/exit monitor with without driver and asyncJob arguments
are moved out of this series. I guess this can be done as soon as this series
is upstream. Most of approach details are in the first patch.

Pros:
- better async job and concurrent regular job isolation
- more straightforward implementation
- more simple to use - no need to pass async job argument down the stack
- safer to use - no warnings to be fixed if function is started to be
  used from asynchronous job context.

TODO:
- replace qemuDomainObjEnterMonitorAsync with qemuDomainObjEnterMonitor
- accomodate callers to qemuDomainObjExitMonitor became returning void
- remove passing driver and asyncJob down the stack
- reflect changes in THREADS.txt
