Switch to using Scalameta/Scalafix's API?

[dwijnand]

MiMa doesn't currently use many Scala-specific aspects from the bytecode. There's a few little bits and pieces, but it mostly doesn't parse the pickled Scala signatures.

This is the major blocker to #34 and the tickets associated with it.

I started to unblock that in #257, but didn't complete the effort.

(As a side note, depending on nsc is problematic for API stability/release reasons too: #193)

So my idea was: why not switch to more modern tooling, with fresh and documented APIs, like Scalameta? In researching this idea I'm told that Scalafix might have some APIs over Scalameta that might be appealing.

But before that: thoughts on the idea?

I started investigating if this is possible by asking in the scalameta/scalameta Gitter room: https://gitter.im/scalameta/scalameta?at=5bd347d5db022f757af4cbae

@olafurpg then also shared that https://github.com/olafurpg/symtab-explorer is an example repo with basic main function.

This is "wontfix". While an interesting idea, MiMa (at least for now) will continue to be based on nsc and the non-pickle info in the bytecode.
