- Moves the creation of `process.binding()`, `process._linkedBinding()`
`internalBinding()` and `NativeModule` into a separate file
`lib/internal/bootstrap_loaders.js`, and documents them there.
This file will be compiled and run before `bootstrap_node.js`, which
means we now bootstrap the internal module & binding system before
actually bootstrapping Node.js.
- Rename the special ID that can be used to require `NativeModule`
as `internal/bootstrap_loaders` since it is setup there. Also put
`internalBinding` in the object exported by `NativeModule.require`
instead of putting it inside the `NativeModule.wrapper`
- Use the original `getBinding()` to get the source code of native
modules instead of getting it from `process.binding('native')`
so that users cannot fake native modules by modifying the binding
object.
- Names the bootstrapping functions so their names show up
in the stack trace.

assert.deepEqual and assert.deepStrictEqual currently return true for
any pair of Maps and Sets regardless of content. This patch adds
support in deepEqual and deepStrictEqual to verify the contents of Maps
and Sets.
Deeo equivalence checking is currently an
O(n^2) operation, and worse, it gets slower exponentially if maps
and sets were nested.
Note that this change breaks compatibility with previous versions of
deepEqual and deepStrictEqual if consumers were depending on all maps
and sets to be seen as equivalent. The old behaviour was never
documented, but nevertheless there are certainly some tests out there
which depend on it.
Support has stalled because the assert API was frozen, but was recently
unfrozen in CTC#63.

Later squashed in:
This change updates the checks for deep equality checking on Map and Set
to check all set values / all map keys to see if any of them match the
expected result.
This change is much slower, but based on the conversation in the pull
request its probably the right approach.

Refactors _deepEqual and fixes a few code paths that lead to
behaviors contradicting what the doc says. Before this commit
certain types of objects (Buffers, Dates, etc.) are not checked
properly, and can get away with different prototypes AND different
enumerable owned properties because _deepEqual would jump to
premature conclusion for them.
Since we no longer follow CommonJS unit testing spec,
the checks for primitives and object prototypes are moved
forward for faster failure.
Improve regexp and float* array checks:
* Don't compare lastIndex of regexps, because they are not
enumerable, so according to the docs they should not be compared
* Compare flags of regexps instead of separate properties
* Use built-in tags to test for float* arrays instead of using
instanceof
Use full link to the archived GitHub repository.

that makes sure the call won't be tampered with.

Do not convert typed arrays to `Buffer` for deepEqual since
their values may not be accurately represented by 8-bit ints.
Instead perform binary comparison of underlying `ArrayBuffer`s,
but only when the array types match.
Never apply any kind of optimization for floating-point typed
arrays since bit pattern equality is not the right kind of check
for them.

Several changes:
* Soft-Deprecate Buffer() constructors
* Add `Buffer.from()`, `Buffer.alloc()`, and `Buffer.allocUnsafe()`
* 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

Instead of leaking the arguments object by passing it as an
argument to a function, copy it's contents to a new array,
then pass the array. This allows V8 to optimize the function
that contains this code, improving performance.

With an indentation style of two spaces, it is not possible to indent
multiline variable declarations by four spaces. Instead, the var keyword
is used on every new line.
Use const instead of var where applicable for changed lines.

`x instanceof f` where f is an arrow function throws a (spec-conforming)
"Function has non-object prototype 'undefined' in instanceof check"
exception.
Add a workaround so that it's possible to pass arrow functions as the
second argument to assert.throws(). The try/catch block is a little
jarring but swapping around the clauses in the if statements changes
the semantics too much.

Many of the util.is*() methods used to check data types
simply compare against a single value or the result of
typeof. This commit replaces calls to these methods with
equivalent checks. This commit does not touch calls to the
more complex methods (isRegExp(), isDate(), etc.).

Currently, JSON.stringify() is used to create error messages

JSON.stringify() for util.inspect(), which can handle
circular references.

Switch condition order to check for null before calling isNaN().
Also remove two unnecessary calls to isNaN() that are already
covered by calls to isFinite(). This commit targets v0.10, as
opposed to #7891, which targets master (suggested by
@bnoordhuis). Closes#7840.

Ensure that the behavior of `assert.deepEqual` does not depend on
argument ordering when comparing an `arguments` object with a
non-`arguments` object.
4716dc6 made assert.equal() and related functions work better by
generating a better toString() from the expected, actual, and operator
values passed to fail(). Unfortunately, this was accomplished by putting
the generated message into the error's `name` property. When you passed
in a custom error message, the error would put the custom error into
`name` *and* `message`, resulting in helpful string representations like
"AssertionError: Oh no: Oh no".
This commit resolves that issue by storing the generated message in the
`message` property while leaving the error's name alone and adding
a regression test so that this doesn't pop back up later.
Closes#5292.
