irmd: Move registry objects to their own sources

Rename internal data structures so it's clear that they are the IRMd
representation of these objects for management purposes.

Split functionality for these objects off and and move them to their
own source files.

Rename internal functions of the IRMd to reflect this, with some small
refactoring.
