I am messing a lot with qemu_driver.c and other QEMU files due
to a multifunction PCI feature I'm working on, ending up
sometimes moving code here and there, sometimes copy and
pasting parts of it, and spreading all these 'vices', namely
using char* and VIR_FREE() and virQEMUDriverConfigPtr with
virObjectUnref(), knowing that there is a better way of doing
it.

Instead of changing just the code I was working on, I took
a leap and ended up changing the whole qemu_driver.c file.
So here it is.

The changes were split to make it reviewing a bit saner. The
commiter can squash these in fewer patches if desirable.

This was done on top of master commit 6ffb8fff9e.

changes in v2:
- addressed review concerns made by Erik
- added more cleanups, as suggested by Erik
