Will Norris 71029cea2d all: update copyright and license headers
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.

Updates #6865

Josh Bleecher Snyder f013960d87 tstime/mono: make json.Unmarshal of a zero time.Time yield a zero Time
This was the proximate cause of #2579.
#2582 is a deeper fix, but this will remain
as a footgun, so may as well fix it too.

Josh Bleecher Snyder 142670b8c2 tstime/mono: new package
Package mono provides a fast monotonic time.

Its primary advantage is that it is fast:
It is approximately twice as fast as time.Now.
This is because time.Now uses two clock calls,
one for wall time and one for monotonic time.

We ask for the current time 4-6 times per network packet.
At ~50ns per call to time.Now, that's enough to show
up in CPU profiles.

Package mono is a first step towards addressing that.
It is designed to be a near drop-in replacement for package time.
