Processor: acquire the BGL for LUs requiring it

If a LU required the BGL (all LUs do, right now, by default) we'll
acquire it in the Processor before starting them. For LUs that don't
we'll still acquire it, but in a shared fashion, so that they cannot run
together with LUs that do.

We'll also note down whether we own the BGL exclusively, and if we don't
and we try to chain a LU that does, we'll fail.

More work will need to be done, of course, to convert LUs not to require
the BGL, but this basic infrastructure should guarantee the coexistance
of the old and new world for the time being.
