Subject: Remodel the Model

- The configuration and crypto model is now entirely independent
  of Android classes other than Nullable and TextUtils.
- Model classes are immutable and use builders that enforce the
  appropriate optional/required attributes.
- The Android config proxies (for Parcelable and databinding) are
  moved to the Android side of the codebase, and are designed to be
  safe for two-way databinding. This allows proper observability in
  TunnelDetailFragment.
- Various robustness fixes and documentation updates to helper classes.
