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.

TestPoolDequeue in long mode does a little more than 1<<21 pushes.
This was originally because the head and tail indexes were 21 bits and
the intent was to test wrap-around behavior. However, in the final
version they were both 32 bits, so the test no longer tested
wrap-around.
It would take too long to reach 32-bit wrap around in a test, so
instead we initialize the poolDequeue with indexes that are already
nearly at their limit. This keeps the knowledge of the maximum index
in one place, and lets us test wrap-around even in short mode.

This adds a dynamically sized, lock-free, single-producer,
multi-consumer queue that will be used in the new Pool stealing
implementation. It's built on top of the fixed-size queue added in the
previous CL.

This is a subset of https://golang.org/cl/20022 with only the copyright
header lines, so the next CL will be smaller and more reviewable.
Go policy has been single space after periods in comments for some time.
The copyright header template at:
https://golang.org/doc/contribute.html#copyright
also uses a single space.
Make them all consistent.
