2021-12-13all: gofmt -w -r 'interface{} -> any' srcRuss Cox
And then revert the bootstrap cmd directories and certain testdata. And adjust tests as needed. Not reverting the changes in std that are bootstrapped, because some of those changes would appear in API docs, and we want to use any consistently. Instead, rewrite 'any' to 'interface{}' in cmd/dist for those directories when preparing the bootstrap copy. A few files changed as a result of running gofmt -w not because of interface{} -> any but because they hadn't been updated for the new //go:build lines. Fixes #49884.

2017-07-20sync: release m.mu during (*RWMutexMap).Range callbacks in sync_testBryan C. Mills
The mainline sync.Map has allowed mutations within Range callbacks since https://golang.org/cl/37342. The reference implementations need to do the same. This change integrates https://go-review.googlesource.com/c/42956/ from x/sync.
