This was a typo in 2e19790f61.
It should have been on `Map` and not on `*Map` as otherwise
it doesn't allow for chaining like `someView.SomeMap().AsMap()`
and requires first assigning it to a variable.

In control there are conditions where the leaf functions are not being
optimized away (i.e. At is not inlined), resulting in undesirable time
spent copying during SliceContains. This optimization is likely
irrelevant to simpler code or smaller structures.

For a second we thought this was allocating but we were looking
at a CPU profile (which showed calls to mallocgc view makeslice)
instead of the alloc profile.
Updates golang/go#65685 (which if fixed wouldn't have confused us)

views.Slice are meant to be immutable, and if used as such it
is at times desirable to use them as a key in a map. For non-viewed
slices it was kinda doable by creating a custom key struct but views.Slice
didn't allow for the same so add a method to create that struct here.

Make it just a views.Slice[netip.Prefix] instead of its own named type.
Having the special case led to circular dependencies in another WIP PR
of mine.

This is basically https://github.com/bradfitz/iter which was
a joke but now that Go's adding range over int soonish, might
as well. It simplies our code elsewher that uses slice views.

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.

This is based on the tagsEqual func from corp/control/control.go, moved
here so that it can be reused in other places.

x/exp/slices now has ContainsFunc (golang/go#53983) so we can delete
our versions.

Also make IPPrefixSliceOf use Slice[netaddr.IPPrefix] as it also
provides additional functions besides the standard ones provided by
Slice[T].
