Pass the scheduler element name instead of trying to reconstructing
it from the attribute name.
This has the benefit of not mixing '%s' with regular text in
translatable strings as well as preventing the confusion when
the 's' marking the plural in the element name ('vcpus') is taken
as a first letter of the 'sched' suffix.

Be less hostile to developers and run the build jobs even
if the dco-check failed. That way they can test their own
"private" branches without a sign-off.
Also specify empty `needs` for it, since it does not depend
on any of the jobs in the container phase and can be run
right away.

When doing an external snapshot we migrate memory to a file as a form of
taking the memory state. This creates a problem as qemu deactivates all
active bitmaps after a successful migration. This means that calling
'query-named-block-nodes' will return an empty list of bitmaps for
devices. We use the bitmap list to propagate the active bitmaps into the
overlay files being created which is required for backups to work after
a snapshot. Since we wouldn't propagate anything a subsequent backup
will fail with:
invalid argument: missing or broken bitmap 'testchck' for disk 'vda'
To fix this, we can simply collect the bitmap list prior to the
migration.

The 'commandhelper' checks effectively whether the parent process is
still around to report whether it was daemonized or not.
This creates a unlikely race condition in cases when we do actually
daemonize the process as the intermediate process used for the
daemonization might not have terminated yet which would report wrong
result leading to test failure.
For now there's just 'test4' which actually daemonizes the process.
Add an argument '--check-daemonize' which asks for retries of the
daemonization check in cases where we expect that the commandhelper is
going to be daemonized and use it in 'test4' to make the test more
reliable.
I've observed the test failure sporadically when my box is under load
e.g. while building two trees at once.

CVE-2020-14339
When building domain's private /dev in a namespace, libdevmapper
is consulted for getting full dependency tree of domain's disks.
The reason is that for a multipath devices all dependent devices
must be created in the namespace and allowed in CGroups.
However, this approach is very fragile as building of namespace
happens in the forked off child process, after mass close of FDs
and just before dropping privileges and execing QEMU. And it so
happens that when calling libdevmapper APIs, one of them opens
/dev/mapper/control and saves the FD into a global variable. The
FD is kept open until the lib is unlinked or dm_lib_release() is
called explicitly. We are doing neither.
However, the virDevMapperGetTargets() function is called also
from libvirtd (when setting up CGroups) and thus has to be thread
safe. Unfortunately, libdevmapper APIs are not thread safe (nor
async signal safe) and thus we can't use them. Reimplement what
libdevmapper would do using plain C (ioctl()-s, /proc/devices
parsing, /dev/mapper dirwalking, and so on).
