common.js needs to be loaded in all tests so that there is checking
for variable leaks and possibly other things. However, it does not
need to be assigned to a variable if nothing in common.js is referred
to elsewhere in the test.
The main tradeoff for this bit of code churn is that it gets the code
base most of the way to being able to enable the no-unused-vars rule in
eslint.
(The non-tooling benefit is that it lessens cognitive load when reading
tests as it is an immediate indication that none of the functions or
properties in common.js will be used by the test.)

Enable linting for the test directory. A number of changes was made so
all tests conform the current rules used by lib and src directories. The
only exception for tests is that unreachable (dead) code is allowed.
test-fs-non-number-arguments-throw had to be excluded from the changes
because of a weird issue on Windows CI.

The copyright and license notice is already in the LICENSE file. There
is no justifiable reason to also require that it be included in every
file, since the individual files are not individually distributed except
as part of the entire package.
Changed ReallyEmit so that it clones the Array of listeners before
processing the emit. Added better tests to make sure that modifying
listeners inside event handlers doesn't cause later listeners to be skipped
or added.
