Include qom/object.h and exec/memory.h instead of exec/ioport.h; exec/ioport.h was almost everywhere required only for those two includes, not for the content of the header itself. Remove block/aio.h, everybody is already including it through another path. With this change, include/hw/hw.h is freed from qemu-common.h. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
