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 check was happening too early and in the case of error would wait 5
s and then error out. This makes it so that it does validations before
the SSH check.

This makes it so that the user is notified that the action
they are about to take may result in them getting disconnected from
the machine. It then waits for 5s for the user to maybe Ctrl+C out of
it.
It also introduces a `--accept-risk=lose-ssh` flag for automation, which
allows the caller to pre-acknowledge the risk.
The two actions that cause this are:
- updating `--ssh` from `true` to `false`
- running `tailscale down`
