In the past we've been using `chunks_exact` because const generics were unstable but then, when they were stabilized we didn't use `as_chunks` (or `array_chunks`) since they were unstable. But the instability was only because Rust devs don't know how to handle `0` being passed in. The function is perfectly implementable on stable. (With a tiny, easy-to-understand `unsafe` block.) `core` doesn't want to make a decision for all other crates yet but we can make it for our own crates because we know that we simply never pass zero. (And even if we did, we could just change the decision.) It also turns out there's a hack to simulate `const {}` block in our MSRV, so we can make compilation fail early. This commit adds an extension trait to internals to provide the methods, so we no longer have to use `chunks_exact`. It also cleans up the code quite nicely. Previous unresolved question, leaving for reference: > One issue with this change is that the names collide which could lead to hard error in future Rust versions. How do we solve it? > * ignore and just backport the fix once that actually happens > * rename the methods to something reasonable (e.g. `as_array_chunks`) - this risks that they'll rename the methods to the same thing by accident and it'll break anyway > * rename the methods to something silly (`bitcoin_as_chunks`) - yeah, the risk above is not there but then we have silly-looking code. We've decide to just rename the methods to something that won't possibly collide.
