This commit adds tests for on(), once(), removeListener(),
and prependOnceListener(), which all throw a TypeError if
the listener argument is not a function.

This commit splits several large event emitter tests into smaller
block scoped tests. This keeps the tests more isolated. This
commit also replaces var with const, assert.equal() with
assert.stictEqual(), and other small enhancements.

When removing a `once` listener, the listener being passed to
the `removeListener` callback is the wrapper. This unwraps the
listener so that `removeListener` is passed the actual listener.

In preparation for a lint rule that will enforce
assert.deepStrictEqual() over assert.deepEqual(), change tests and
benchmarks accordingly. For tests and benchmarks that are testing or
benchmarking assert.deepEqual() itself, apply a comment to ignore the
upcoming rule.

This commit updates events doc to describe removeListener behaviour
when it is called within a listener. An example is added to make
it more evident.
A test is also incuded to make this behaviour consistent in future
releases.

Currently there are many instances where assert.fail is directly passed
to a callback for error handling. Unfortunately this will swallow the
error as it is the third argument of assert.fail that sets the message
not the first.
This commit adds a new function to test/common.js that simply wraps
assert.fail and calls it with the provided message.
Tip of the hat to @trott for pointing me in the direction of this.

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 order of the `newListener` and `removeListener` events with respect
to the actual adding and removing from the underlying listeners array
should be deterministic. There is no compelling reason for leaving it
indeterminate. Changing the ordering is likely to result in breaking
code that was unwittingly relying on the current behaviour, and the
indeterminancy makes it impossible to use these events to determine when
the first or last listener is added for an event.

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.
This reverts commit 928ea564d1.
Keeping the original Array instance in-place essentially causes a memory leak
on EventEmitters that use an infinite number of event names (an incrementing
counter, for example), which isn't an unreasonable thing to want to do.
Fixes#3702.
