This is an implementation of RFC 3192 (which is yet to be merged, thus why this is a draft PR). It adds an API for type-driven requests and provision of data from trait objects. A primary use case is for the Error trait, though that is not implemented in this PR. The only major difference to the RFC is that the functionality is added to the any module, rather than being in a sibling provide_any module (as discussed in the RFC thread).

Still todo: improve documentation on items, including adding examples.

Sorry for taking a while for getting to this.

While some of the comments I'm confident in, others I'm not tied to at all. As always, feel free to push back on anything you feel differently about.
