Allow the user to inhibit caching of object classes #26

Closed dankamongmen closed 5 years ago

dankamongmen commented 5 years ago

Right now it's all or nothing. The user ought be allowed to supply some manner of bitmask, though interfaces can't ever really be disabled...with our current design, anyway.

Note that we can't base this solely on which callbacks are set, since we still would want to support lookups and enumeration-on-demand even for those we don't provide callbacks for. Saying "I'm uninterested" doesn't mean "don't send a discovery request", but rather "don't deal with these at all."

I've implemented this for ifaces now (the only thing we actually cache yet). Need a unit test for this.
