OK patch dropped.

I suggest we could adopt this system. Right now we have log categories
and log levels, we could create a metadata category (if that doesn't
already exist), and allow some specification of the kind:
-loglevel [category:]level

which controls *only* the level of the category if specified.

So you could have
-loglevel metadata:quiet if you don't care about metadata.
