For syntax extensions (and possibly semantic extensions) to load in from external crates, we need to dynamically load them. Currently the library-scanning machinery is a bit too weak to handle this, and there's no os-level interface in the standard library for fetching symbols from a loaded library. Implement all this.

Doing this in a safe way is likely blocked on #2213

I don't believe this is backwards incompatible, renominating.

#7027 is a solid step forward on this.

This is implemented, and there are tests for it in src/libstd/unstable/dynamic_lib.rs.

The caveat I have here is that the interface isn't typesafe. Only works with symbols with mangling turned off. Guess the bug didn't mention that but imo it's important.

High, but not 1.0

This is done, minus safety. Replacing with #15040
