rather than the uint32_t for which the maximum is slightly more than 4
seconds and larger values would overflow. The QAPI interface allows
specifying the number of seconds, so only values 0 to 4 are safe right
now, other values lead to a much lower timeout than a user expects.

If a blockcommit is aborted the base image remains in RW mode, that leads
to a fail of subsequent live migration.
How to reproduce:
$ virsh snapshot-create-as vm snp1 --disk-only
*** write something to the disk inside the guest ***
$ virsh blockcommit vm vda
Add a parameter that enables discard-after-copy. That is mostly useful
in "push backup with fleecing" scheme, when source is snapshot-access
format driver node, based on copy-before-write filter snapshot-access
API:
[guest] [snapshot-access] ~~ blockdev-backup ~~> [backup target]

Currently block_copy creates copy_bitmap in source node. But that is in
bad relation with .independent_close=true of copy-before-write filter:
source node may be detached and removed before .bdrv_close() handler
called, which should call block_copy_state_free(), which in turn should
remove

First thing that crashes on unligned access here is

In case when source node does not have any parents, the condition still
works as required: backup job do create the parent by
block_job_create -> block_job_add_bdrv -> bdrv_root_attach_child
Still, in this case checking @perm variable doesn't work, as backup job

Here we just prepare for the following patch, making possible to report
GenericError as recommended.
This patch doesn't aim to prevent further use of DeviceNotFound by
future interfaces:
- find_device_state() is used in blk_by_qdev_id() and qmp_get_blk()
