Update all code generation tools, and those that check for license
headers to use the new standard header.
Also update copyright statement in LICENSE file.

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.

The "go generate" command blindly looks for "//go:generate" anywhere
in the file regardless of whether it is truly a comment.
Prevent this false positive in cloner.go by mangling the string
to look less like "//go:generate".

Emit a go:generate pragma with the full set of flags passed to cloner.
This allows the user to simply run "go generate" at the location
of the generate file to reproduce the file.

The fully qualified name of the type is thisPkg.tname,
so write the args like that too.

And in the process, fix a bug:
The fmt formatting was being applied by writef,
not fmt.Sprintf, thus emitting a MISSING string.
And there's no guarantee that fmt will be imported
in the generated code.

Change from a single-case type switch to a type assertion
with an early return.
That exposes that the name arg to gen is unneeded.

This is a package for shared utilities used in doing codegen programs.
The inaugural API is for writing gofmt'd code to a file.

Spelling out the command to run for every type
means that changing the command makes for a large, repetitive diff.
Stop doing that.

In order to clone DERPMaps, it was necessary to extend the cloner so that it supports
nested pointers inside of maps which are also cloneable. This also adds cloning for DERPRegions
and DERPNodes because they are on DERPMap's maps.

This Clone function knows how to clone any types
for which it has generated Clone methods.
This allows callers to efficiently clone
an inbound interface{} that might contain one of these types.

This was causing any type to be reported as found,
as long as there were any type decls at all. Oops.

If you change a struct and don't re-run cloner,
your Cloner method might be inaccurate, leading to bad things.
To prevent this, write out the struct as it is at the moment that
cloner is caller, and attempt a conversion from that type.
If the struct gets changed in any way, this conversion will fail.
This will yield false positives: If you change a non-pointer field,
you will be forced to re-run cloner, even though the actual generated
code won't change. I think this is an acceptable cost: It is a minor
annoyance, which will prevent real bugs.
