The reverse proxy was sending the ingressd IPv6 down as the
X-Forwarded-For. This update uses the actual remote addr.

This change trims the mountPoint from the request URL path before
sending the request to the reverse proxy.
Today if you mount a proxy at `/foo` and request to
`/foo/bar/baz`, we leak the `mountPoint` `/foo` as part of the request
URL's path.
This fix makes removed the `mountPoint` prefix from the path so
proxied services receive requests as if they were running at the root
(`/`) path.
This could be an issue if the app generates URLs (in HTML or otherwise)
and assumes `/path`. In this case, those URLs will 404.
With that, I still think we should trim by default and not leak the
`mountPoint` (specific to Tailscale) into whatever app is hosted.
If it causes an issue with URL generation, I'd suggest looking at configuring
an app-specific path prefix or running Caddy as a more advanced
solution.

Previously the part that handled Funnel connections was not
aware of any listeners that tsnet.Servers might have had open
so it would check against the ServeConfig and fail.
Adding a ServeConfig for a TCP proxy was also not suitable in this
scenario as that would mean creating two different listeners and have
one forward to the other, which really meant that you could not have
funnel and tailnet-only listeners on the same port.
This also introduces the ipn.FunnelConn as a way for users to identify
whether the call is coming over funnel or not. Currently it only holds
the underlying conn and the target as presented in the "Tailscale-Ingress-Target"
header.

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.

On macOS (AppStore and macsys), we need to bind to ""/all-interfaces
due to the network sandbox. Ideally we would only bind to the
Tailscale interface, but macOS errors out if we try to
to listen on privileged ports binding only to a specific
interface.
We also implement the lc.Control hook, same as we do for
peerapi. It doesn't solve our problem but it's better that
we do and would likely be required when Apple gets around to
fixing per-interface priviliged port binding.

By default, `http.Transport` keeps idle connections open hoping to re-use them in the future. Combined with a separate transport per request in HTTP proxy this results in idle connection leak.
Fixes#6773
Even if the name is right, or is configured on a different port.
