Warning: breaking changes up ahead!

Fixes #510

This change removes the Core variants of types, traits, and functions that we introduced in #426. However, this means it introduces breaking changes, specifically where we used Data parameters in the past we now use Container. This is desirable because maintaining the old facade comes with a cognitive overhead. After this change, most places that previously specified individual elements now specify containers. All places that only apply to specific (mostly Vec<_>) containers are exepted.

The most notable breaking changes are in inputs, to_stream, and feedback, which now need to know the kind of container they produce. In the past, they were fixed to Vec<_>, but now the caller needs to be explicit about it.

The PR looks rather large, but most of the changes are purely mechanical. For wildly-used types, there is a commit that inlines the non-core variant, and a follow-up to rename the core-variant to the old name. This should make it explicit that each change has limited scope. Tests should pass after each individual change.

  • 60ae900 changes inputs to containers.
  • 5987d4c changes feedback to use containers.
