Move several packages to internal/ (#365)

## Summary
Moves most packages to `internal/`. There's still some other files I
want to move/refactor, but this takes care of the bulk. The idea is to
check this in quickly to minimize merge conflicts, and I can do the
smaller refactors separately.

## How was it tested?
`go test -v ./...`
