This patch updates domaincapsdata and qemucapabilitiesdata for ppc64
with qemu commit v6.1.0-1714-gc5b2f55981.
Changes in all 'ppc64-latest.ags' files were needed. The changes are
mundane despite the volume. For all 'ppc64-latest.args' files the
changes are:
- removing '-sandbox' command line;
- 'secret' and 'memory-backend-ram' objects are now using qom-type format;
- '-device' is now using qom-type format.

In a few cases we call a public API, wrapped in an if() statement
with both branches written out explicitly. The error branch jumps
onto cleanup label, while the successful prints out a message.
Right after these ifs there's 'ret = true;' and the cleanup
label. The code is a bit more readable if only the error branch
is kept and printing happens at the same level as setting the ret
variable.

Currently, the dommigrate example returns 0 or 1 for success or
failure state, respectively. Except for a few cases where it
forgot to change the @ret variable just before jumping onto the
'cleanup' label. Making the code follow our usual pattern
(initialize @ret to an error value and set it to success value
only at the end) fixes those cases. Also, using EXIT_SUCCESS and
EXIT_FAILURE is more portable (even though on my system they are
just an alias to values the example already uses).

Similarly to one of previous commits, there's no need to
increment domain object refcounter before unlocking it. Any
number of lock and unlock calls over domain object has no effect
on the refcounter.

Currently, when opening an agent socket the qemuConnectAgent()
increments domain object refcounter and calls qemuAgentOpen()
where the domain object pointer is simply stored inside
_qemuAgent struct. If qemuAgentOpen() fails, then it clears @cb
member only to avoid qemuProcessHandleAgentDestroy() being called
(which decrements the domain object refcounter) and the domain
object refcounter is then decreased explicitly in
qemuConnectAgent().
The same result can be achieved with much cleaner code: increment
the refcounter inside qemuAgentOpen() and drop the dance around
@cb.
Also, the comment in qemuConnectAgent() about holding an extra
reference is not correct. The thread that called
qemuConnectAgent() already holds a reference to the domain
object. No matter how many time the object is locked and unlocked
the reference counter can't be decreased.

Just like qemuMonitorOpen(), hold the domain object locked
throughout the whole time of qemuConnectAgent() and unlock it
only for a brief time of actual connect() (because this is the
only part that has a potential of blocking).
The reason is that qemuAgentOpen() does access domain object
(well, its privateData) AND also at least one argument (@context)
depends on domain object. Accessing these without the lock is
potentially dangerous.

Commit 88957116c9 switched to use
memory-backend-* for regular VM memory as well. That change indirectly
started using 'host-nodes' for system memory which results in QEMU
calling mbind() to bind the system memory to specific NUMA node if the
VM XML contains the configuration similar to this:
...
<numatune>
<memory mode='strict' nodeset='0'/>
</numatune>
...
Once the VM was started with that configuration it was no longer
possible to change the memory NUMA nodeset.
