irm: Revise naming API

This revises the naming API to treat names (or reg_name in the source)
as first-class citizens of the architecture. This is more in line with
the way they are described in the article.

Operations have been added to create/destroy names independently of
registering. This was previously done only as part of register, and
there was no way to delete a name from the IRMd.  The create call now
allows specifying a policy for load-balancing incoming flows for a
name. The default is the new round-robin load-balancer, the previous
behaviour is still available as a spillover load-balancer.

The register calls will still create a name if it doesn't exist, with
the default round-robin load-balancer.

The tools now have a "name" section, so the format is now

irm name <operation> <name> ...
