07b54c3d5a qemu_monitor: introduce qemuMonitorJobFinalize
Upcoming snapshot deletion code will require that multiple commit jobs
are finished in sync. To allow aborting then if one fails we will need
to use manual finalization of the jobs.

This commit implements the monitor code for `job-finalize`.

e152f0718f qemu: Always check nodeset provided to numatune
Up until commit 629282d884, using mode=restrictive caused
virNumaSetupMemoryPolicy() to be called from qemuProcessHook(),
and that in turn resulted in virNumaNodesetIsAvailable() being
called and the nodeset being validated.

After that change, the only validation for the nodeset is the one
happening in qemuBuildMemoryBackendProps(), which is skipped when
using mode=restrictive.

Make sure virNumaNodesetIsAvailable() is called whenever a
nodeset has been provided by the user, regardless of the mode.

7050dad5f9 qemu: Remember failed post-copy migration in job
When post-copy migration fails, the domain stays running on the
destination with a VIR_DOMAIN_RUNNING_POSTCOPY_FAILED reason. Both the
state and the reason can later be rewritten in case the domain gets
paused for other reasons (such as an I/O error). Thus we need a separate
place to remember the post-copy migration failed to be able to resume
the migration.

The parameter was only used to select which states correspond to an
active or failed post-copy migration. But these states are either
applicable to both operations or the check would just paper over a code
bug in case of an impossible combination of state and operation. By
dropping the check we can make the code simpler and also reuse existing
virDomainObjIsFailedPostcopy function and only check for active
post-copy states.

8f95ef95d6 virQEMUDriverGetDomainCapabilities: Validate arguments
When calling virConnectGetDomainCapabilities() (exposed as virsh
domcapabilities) users have option to specify whatever sub-set of
{ emulatorbin, arch, machine, virttype } they want. Then we have
a logic (hidden in virQEMUCapsCacheLookupDefault()) that picks
qemuCaps that satisfy values passed by user. And whatever was not
specified is then set to the default value as specified by picked
qemuCaps. For instance: if no machine type was provided but
emulatorbin was, then the machine type is set to the default one
as defined by the emulatorbin.

Or, when just virttype was set then the remaining three values
are set to their respective defaults. Except, we have a crasher
in this case:

  # virsh domcapabilities --virttype hvf
  error: Disconnected from qemu:///system due to end of file
  error: failed to get emulator capabilities
  error: End of file while reading data: Input/output error

This is because for 'hvf' virttype (at least my) QEMU does not
have any machine type. Therefore, @machine is set to NULL and the
rest of the code does not expect that.

What we can do about this is to validate all arguments. Well,
except for the emulatorbin which is obtained from passed
qemuCaps. This also fixes the issue when domcapabilities for a
virttype of a different driver are requested, or a different
arch.
