Per [1] the Debian 10 reaches EOL in August of 2022. This allows us to
bump the minimum supported qemu version to qemu-4.2 which will also
allow us to do significant cleanups.
This commit bumps the minimum qemu verison and updates the corresponding
docs.

Since we started handling the monitor EOF event inside a job any code
which uses virDomainObjWait would no longer properly abort in case when
the VM crashed during the wait.
This is because virDomainObjWait uses virDomainObjIsActive which checks
'vm->def->id' to see if the VM is still active. Unfortunately the domain
id is cleared in qemuProcessStop which is run only inside the job.
To fix this we can use the 'beingDestroyed' flag stored in the VM
private data which is set to true around the time when the condition is
signalled.
