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.

One current theory (among other things) on battery consumption is that
magicsock is resorting to using the IPv6 over LTE even on WiFi.
One thing that could explain this is that we do not get link change updates
for the LTE modem as we ignore them in this list.
This commit makes us not ignore changes to `pdp_ip` as a test.

Currently we ignore these interfaces in the darwin osMon but then would consider it
interesting when checking if anything had changed.

Should help iOS battery life on NEProvider.wake/skip events
with useless route updates that shouldn't cause re-STUNs.

Not great, but lets people working on new ports get going more quickly
without having to do everything up front.
As the link monitor is getting used more, I felt bad having a useless
implementation.

We used to allow that, but now it just crashes.
Separately I need to figure out why it got into this path at all,
which is #1416.

Don't use os.NewFile or (*os.File).Close on the AF_ROUTE socket. It
apparently does weird things to the fd and at least doesn't seem to
close it. Just use the unix package.
The test doesn't actually fail reliably before the fix, though. It
was an attempt. But this fixes the integration tests.

Previously tailscaled on macOS was running "/sbin/route monitor" as a
child process, but child processes aren't allowed in the Network
Extension / App Store sandbox. Instead, just do what "/sbin/route monitor"
itself does: unix.Socket(unix.AF_ROUTE, unix.SOCK_RAW, 0) and read that.
We also parse it now, but don't do anything with the parsed results yet.
We will over time, as we have with Linux netlink messages over time.
Currently any message is considered a signal to poll and see what changed.
