Update plugin handling to follow the smart pointers used in the svcore library. This is awkward in our context, and the outcome isn't a very nice one - but it
does look as if we had the potential for use-after-free in cases where a plugin
was both used "bare" and wrapped in an auto-deleting adapter; those should be
fixed now
