qemu: Move PostParse functions out of qemu_domain.c

Problem with qemu_domain.c is that it's constantly growing. But
there are few options for improvement. For instance, validation
functions were moved out and now live in qemu_validate.c. We can
do the same for PostParse functions, though since PostParse may
modify domain definition, some functions need to be exported from
qemu_domain.c.
