Like we do for the ones on iOS.
As a bonus, this removes a caller of tsaddr.IsTailscaleIP which we
want to revamp/remove soonish.

Otherwise on OS retransmits, we'd make redundant timers in Go's timer
heap that upon firing just do nothing (well, grab a mutex and check a
map and see that there's nothing to do).

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.

Avoid contention from fetching status for all peers, and instead fetch
status for a single peer.

A new package can also later record/report which knobs are checked and
set. It also makes the code cleaner & easier to grep for env knobs.

This removes the first two of the four callers.

And in the process, fix the related confusing error messages from
pinging your own IP or hostname.

magicsock makes multiple calls to Now per packet.
Move to mono.Now. Changing some of the calls to
use package mono has a cascading effect,
causing non-per-packet call sites to also switch.

The connection failure diagnostic code was never updated enough for
exit nodes, so disable its misleading output when the node it picks
(incorrectly) to diagnose is only an exit node.

This necessarily moves code up from magicsock to wgengine, so we can
look at the actual wireguard config.

Add proto to flowtrack.Tuple.
Add types/ipproto leaf package to break a cycle.
Server-side ACL work remains.

And move a couple other types down into leafier packages.
Now cmd/tailscale doesn't bring in netlink, magicsock, wgengine, etc.

Unused for now, but I want to backport this commit to 1.4 so 1.6 can
start sending these and then at least 1.4 logs will stringify nicely.

This adds a new IP Protocol type, TSMP on protocol number 99 for
sending inter-tailscale messages over WireGuard, currently just for
why a peer rejects TCP SYNs (ACL rejection, shields up, and in the
future: nothing listening, something listening on that port but wrong
interface, etc)
