TestMonitorMode skips by default, without the --monitor flag, and then
it previously ran forever. This adds an option --monitor-duration flag
that defaults to zero (run forever) but if non-zero bounds how long
the tests runs. This means you can then also use e.g. `go test
--cpuprofile` and capture a CPU/mem profile for a minute or two.

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.

The Engine.LinkChange method was recently removed in
e3df29d488 while misremembering how
Android's link state mechanism worked.
Rather than do some last minute rearchitecting of link state on
Android before Tailscale 1.6, restore the old Engine.LinkChange hook
for now so the Android client doesn't need any changes. But change how
it's implemented to instead inject an event into the link monitor.

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.
