Auto merge of #53533 - withoutboats:error-source, r=withoutboats
Add Error::source method per RFC 2504. This implements part of RFC 2504. * Adds `Error::source`, a replacement for `Error::cause` with the "right" signature, which will be instantly stable. * Deprecates `Error::cause` in 1.33 (this choice was based on the precedent in #52994, which we haven't finalized). * Redefines `Error::cause` to delegate to `Error::source` (the delegation can only go in this direction, not the other). @rfcbot fcp merge
