We have some flaky integration tests elsewhere that have no one place
to ask about the state of the world. This makes LocalBackend be that
place (as it's basically there anyway) but doesn't yet add the ForTest
accessor method.
This adds a LocalBackend.peers map[NodeID]NodeView that is
incrementally updated as mutations arrive. And then we start moving
away from using NetMap.Peers at runtime (UpdateStatus no longer uses
it now). And remove another copy of NodeView in the LocalBackend
nodeByAddr map. Change that to point into b.peers instead.
Future changes will then start streaming whole-node-granularity peer
change updates to WatchIPNBus clients, tracking statefully per client
what each has seen. This will get the GUI clients from receiving less
of a JSON storm of updates all the time.

This PR adds optimistic concurrency control in the local client and
api in order to ensure multiple writes of the ServeConfig do not
conflict with each other.

Adds a `Tailscale-Headers-Info` header whenever the `Tailscale-User-`
headers are filled from the HTTP proxy handler.
Planning on hooking this shorturl up to KB docs about the header
values (i.e. what's a login name vs. display name) and security
considerations to keep in mind while using these headers - notibly
that they can also be filled from external requests that do not hit
tailscaled.

Adds two new headers to HTTP serve proxy:
- `Tailscale-User-Login`: Filled with requester's login name.
- `Tailscale-User-Name`: Filled with requester's display name.
These headers only get filled when the SrcAddr is associated with
a non-tagged (i.e. user-owned) node within the client's Tailnet.
The headers are passed through empty when the request originated
from another tailnet, or the public internet (via funnel).

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.
