511bdb0bb2 qemu: don't raise error upon interface update without <frames/> for <rx/> in coalesce
With this, incomplete XML without <frames/> for <rx/> in coalesce
won't raise error as before. It will leave the coalesce parameter
empty, thanks to passing it as a parameter and return an integer
to indicate error state - previously it returned pointer (or NULL
for both error and incomplete XML).
I also added a test case to test this functionality in the
qemuxml2xmltest.

The code went through some refactoring:
* change of a condition
* addition of a parameter
* change of order, that allowed removal of VIR_FREE
* removal of redundant labels and variables

e2602f2bb1 domain_cgroup.c: update domain after setting blkio.weight
Commit ac87d3520a consolidated common cgroup code between the QEMU and
lxc drivers in domain_cgroup.c. In this process, in
virDomainCgroupSetupDomainBlkioParameters(), a call to
virCgroupGetBlkioWeight() went missing.

The result is that 'virsh blkiotune' is setting the blkio.weight for the
guest in the host cgroup, but not on the domain XML, because
virCgroupGetBlkioWeight() is also used to write the blkio.weight value
in the domain object.

Fix it by adding the virCgroupGetBlkioWeight() call in the
virDomainCgroupSetupDomainBlkioParameters() helper.

4f33b817b2 qemu: command: Use JSON for QAPIfied -object directly
Skip the lossy conversion to legacy commandline arguments by using the
JSON props directly when -object is QAPIfied. This avoids issues with
conversion of bitmaps and also allows validation of the generated JSON
against the QMP schema in the tests.

Since the new approach is triggered by a qemu capability the code
from 'virQEMUBuildObjectCommandlineFromJSON' in util/virqemu.c was moved
to 'qemuBuildObjectCommandlineFromJSON' in qemu/qemu_command.c which has
the virQEMUCaps type.

Some functions needed to be modified to propagate qemuCaps.

8967ad7be6 qemu: backup: Restore security label on backup disk store image on VM termination
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.
