("[PATCH] cpu: fix memleak of 'halt_cond' and 'thread'")

I saw various sanitizer errors when running check-qtest-ppc64. While
I could just turn off sanitizers, I decided to tackle them this time.

Unfortunately, GLib does not free test data in some cases so some
sanitizer errors remain. All sanitizer errors will be gone with this
patch series combined with the following change for GLib:

Maybe needs to be split. Mark had an alternative for macio which was 
picked up by Philippe if I'm not mistaken. I've sent an alternative for 
vt82c686 which is still discussed but could belong to Philippe as well. 
PPC parts could be taken by the PPC maintainers if there were any active 
at the moment and I don't know who maintains tests normally or other misc 
areas.

I can take the qtest patches through my tree.

These are all core code, maybe Philippe, Peter, or Richard,
Fabiano for migration perhaps?

I guess I'll let you wrangle these and go through Philippe then?

These ppc ones I can take, they seem okay. Sorry for my recent
inactivity.
