Gonglei 76349f5ba8 bootdevice: add check in restore_boot_order()
qemu_boot_set() can't fail in restore_boot_order(),
then simply assert it doesn't fail, by passing
&error_abort if boot_set_handler set.

Gonglei 0be63901d2 qdev: support to get a device firmware path directly
commit 6b1566c (qdev: Introduce FWPathProvider interface) did a
good job for supproting to get firmware path on some different
architectures.

Moreover further more, we can use the interface to get firmware
path name for a device which isn't attached a specific bus,
such as virtio-bus, scsi-bus etc.

When the device (such as vhost-scsi) realize the TYPE_FW_PATH_PROVIDER
interface, we should introduce a new function to get the correct firmware
path name for it.

Gonglei ddcd55316f bootdevice: add Error **errp argument for QEMUBootSetHandler
It will be useful for checking when we change traditional
boot order dynamically and propagate error message
to the monitor.
For x86 architecture, we pass &local_err to set_boot_dev()
when vm startup in pc_coms_init().

Gonglei 9816833d3b bootdevice: move code about bootorder from vl.c to bootdevice.c
First, we can downsize vl.c, make it simpler by
little and little. Second, I can maintain those code
and make some improvement.
