This is a followup PR to #433. This changes sdf::Root to have only one Actor/Light/Model.

This change will introduce a hard break to the root element.

We usually do a tick-tock cycle on public APIs so I think we need to first deprecate the member functions in Root in libsdformat11 and then remove them in libsdformat12.

Makes sense, I'll plan on updating this PR

Deprecated the original methods and adjusted their logic for the addition of the unique_ptr. I also rebased onto master, so this should be easier to review now.

In this last commit, I've switched model/light/actor to being stored as part of a std::variant so that the implementation better matches the sdf spec. It adds more lines than the unique_ptr variation, but better enforces the spec.

I'm happy to switch back though.

I'm not sure if deprecating these member variables is useful here, as compiling this file creates a bunch of warnings.

Yeah, I would only deprecate the public API. Stuff in RootPrivate is all private.

LGTM! Thanks for iterating. Could you add the deprecations to Migration.md before merging?

Emit an error instead of a warning when a file has multiple root level (
2d298f0 
#619)

#433 and #444 made it so that only one root level model, actor or light can be contained in an SDFormat file. So as to not break existing behavior, only a warning was issued if more than one is found. These have now been converted to errors. This PR also removes deprecated functions for accessing multiple model, actor or light elements from sdf::Root.
