trussed 0.1.0

// NOTE: The mechanism implementations are currently littered with `#[inline(never)]`,
// which is annoyingly explicit + manual (easy to forget).
// The underlying concern is that the stack use of `ServiceResources::reply_to` would be
// "too big" if they all get inlined.
//
// Removing these inlines (2021-03-12) changes the `text` code size of an entire solo-bee
// firmware from 350416 to 351376 (larger), so it's at least not obvious that these inlines
// happen.
//
// The question of breaking down `reply_to` into smaller, more globally understandable pieces,
// should be revisited.
