There's no way to cancel the current executing dump process, lead to the
virtual machine manager daemon((e.g. libvirtd) cannot restore the dump
job after daemon restart.
Add the 'cancelling' and 'cancelled' dump states.
Use 'dump-cancel' qmp command Set the dump state as 'cancelling'.

Depending on how the target list is sorted in by qemu, the first target
(used as the base copy of the fuzzer, to which all others are linked)
might not be a generic-fuzzer. Since we are trying to only use
generic-fuzz, on oss-fuzz, fix that, to ensure the base copy is a
generic-fuzzer.

Since we express dependancies via a 'needs' clause, we don't need to
split container builds into separate stages. GitLab happily lets jobs
depend on other jobs in the same stage and will run them when possible.

When tests fail meson just displays a summary and tells you to look at

Mostly this is to get the latest libvirt-ci content pulled in,
