Brad Fitzpatrick 1a963342c7 util/set: add Of variant of SetOf that takes variadic parameter
set.Of(1, 2, 3) is prettier than set.SetOf([]int{1, 2, 3}).

I was going to change the signature of SetOf but then I noticed its
name has stutter anyway, so I kept it for compatibility. People can
prefer to use set.Of for new code or slowly migrate.

Also add a lazy Make method, which I often find myself wanting,
without having to resort to uglier mak.Set(&set, k, struct{}{}).

util/set: implement json.Marshaler/Unmarshaler (#10308)
Marshal as a JSON list instead of a map. Because set elements are
`comparable` and not `cmp.Ordered`, we cannot easily sort the items
before marshaling.

Brad Fitzpatrick dc7aa98b76 all: use set.Set consistently instead of map[T]struct{}
I didn't clean up the more idiomatic map[T]bool with true values, at
least yet.  I just converted the relatively awkward struct{}-valued
maps.

We have two other types of Sets here. Add the basic obvious one too.

Needed for a change elsewhere.

Will Norris 71029cea2d all: update copyright and license headers
This updates all source files to use a new standard header for copyright
and license declaration.  Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

Updates #6865

Brad Fitzpatrick ea25ef8236 util/set: add new set package for SetHandle type
We use this pattern in a number of places (in this repo and elsewhere)
and I was about to add a fourth to this repo which was crossing the line.
Add this type instead so they're all the same.

Also, we have another Set type (SliceSet, which tracks its keys in
order) in another repo we can move to this package later.
