whitequark 2648b1b7a1 firmware: migrate to Rust 1.28.0.
This also updates / is a prerequisite for updating smoltcp.

Rationale for changes made:
  * compiler_builtins is now shipped in the rust prefix.
  * rustc's libpanic_unwind no longer works for us because it
    has a hard dependency on Box (and it's a horrible hack);
    fortunately, we only ever needed a personality function
    from it.
  * panic and oom handlers are now set in a completely different
    way.
  * allocators are quite different (and finally stable).
  * NLL caused internal compiler errors in runtime, so code using
    NLL was rewritten to not rely on it and it was turned off.
