The main objective of this patch is to use a proper instance of
virDomainChrSourceDef allocated with the private data.
To achieve this the test cases are grouped into blocks by how much they
fill in the chardev definition. Some test cases are moved around so
that the resulting sequence doesn't need extra clearing.

Our code uses fdsets for the pipe passed from virtlogd to qemu, but the
chardev hot-unplug code neglected to detach the fdset after the chardev
was removed. This kept the FDs open by qemu even after they were not
used any more.
After the refactor to use qemuFDPass for chardevs we now configure the
'opaque' field for fdsets used for chardevs so we can use
qemuHotplugRemoveFDSet to remove the unused fdset.

Rewrite the parts which already pass FDs via fdset or directly to use
the new infrastructure.
Apart from simpler code this also adds the appropriate names to the fds
in the fdsets which will allow us to properly remove the fdsets won
hot-unplug of chardevs, which we didn't do for now and resulted in
leaking the FDs.

For now we have only one code path ('vdpa' interface) which actually
cleans up the fdset after it's done, but there are more device types
using fdsets.
In order to unify the handling of fdsets the removal code will now be
able to remove fdsets based on a prefix of the 'opaque' field, which
we'll always prefix with a device alias or e.g. node name once fdsets
are also used for disk backing.
To keep compatibility with old QEMUs, retain the possibility for the
VDPA interface to use the path.

When starting a VM we must assign unique IDs for fdsets we add via
'-add-fd'. For now it was done by using the index of the filedescriptor
passed to the virCommand. That approach is not very flexible, because
you need to have already passed the 'fd' to virCommand before generating
the fdset path, and also won't nicely work with fdsets containing two or
more fds.
This patch introduces a counter into the private data of a qemu domain
so that we can allocate unique ids without relying on virCommand.
