qom: add QObject-based property get/set wrappers
Move the creation of QmpInputVisitor and QmpOutputVisitor from qmp.c to qom/object.c, since it's the only practical way to access object properties. Keep this isolated such that it's easy to remove. At some point, we need to remove all usage of QObject in the tree and replace it with GVariant. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
