bgpwtf/cccampix: add IRR daemon

We add a small IRR service for getting a parsed RPSL from IRRs. For now,
we only support RIPE and ARIN, and only the following attributes:
 - remarks
 - import
 - export

Since RPSL/RFC2622 is fucking insane, there is no guarantee that the
parser, especially the import/export parser, is correct. But it should
be good enough for our use. We even throw in some tests for good
measure.
