Using the black magic of Symbol.toPrimitive the numeric value of
start/end can be changed when Uint32Value() is called once
Buffer::Fill() is entered. Allowing the CHECK() to be bypassed.
The bug report was only for "start", but the same can be done with
"end". Perform checks for both in node::Buffer::Fill() to make sure the
issue can't be triggered, even if process.binding is used directly.
Include tests for each case. Along with a check to make sure the last
time the value is accessed returns -1. This should be enough to make
sure Buffer::Fill() is receiving the correct value. Along with two tests
against process.binding directly.

Remove duplication of buffer tests, separate out into separate
files, update and cleanup code, move to using strictEqual where
possible.

When node began using the OneByte API (f150d56) it also switched to
officially supporting ISO-8859-1. Though at the time no new encoding
string was introduced.
Introduce the new encoding string 'latin1' to be more explicit. The
previous 'binary' and documented as an alias to 'latin1'. While many
tests have switched to use 'latin1', there are still plenty that do both
'binary' and 'latin1' checks side-by-side to ensure there is no
regression.

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.

* Add `--zero-fill-buffers` command line option
* Add byteOffset and length to `new Buffer(arrayBuffer)` constructor
* buffer.fill('') previously had no effect, now zero-fills
* Update the docs

Can now call fill() using following parameters if value is a String:
fill(string[, start[, end]][, encoding])
And with the following if value is a Buffer:
fill(buffer[, start[, end]])
The encoding is ignored if value is not a String. All other non-Buffer
values are coerced to a uint32.
A multibyte strings will simply be copied into the Buffer until the
number of bytes run out. Meaning partial strings can be left behind:
Buffer(3).fill('\u0222');
// returns: <Buffer c8 a2 c8>
In some encoding cases, such as 'hex', fill() will throw if the input
string is not valid.
