[Diffie-Hellman](https://en.wikipedia.org/wiki/Diffie%E2%80%93Hellman_key_exchange#Cryptographic_explanation)
keys are composed of a `generator` a `prime` a `secret_key`
and the `public_key` resulting from the math operation:
```
(generator ^ secret_key) mod prime = public_key
```
Diffie-Hellman keypairs will compute a matching shared secret
if and only if the generator and prime match for both
recipients. The generator is usually **2** and the prime is
what is called a [Safe Prime](https://en.wikipedia.org/wiki/Safe_prime).
Usually this matching is accomplished by using
[standard published groups](http://tools.ietf.org/html/rfc3526).
We expose access those groups with the `crypto.getDiffieHellman`
function.
`createDiffieHellman` is trickier to use. The original example
had the user creating 11 bit keys, and creating random groups of
generators and primes. 11 bit keys are very very small, can be
cracked by a single person on a single sheet of paper. A
byproduct of using such small keys were that it was a high
likelihood that two calls of `createDiffieHellman(11)` would
result in using the same 11 bit safe prime.
The original example code would fail when the safe primes generated
at 11 bit lengths did not match for alice and bob.
If you want to use your own generated safe `prime` then the proper
use of `createDiffieHellman` is to pass the `prime` and `generator`
to the recipient's constructor, so that when they compute the shared
secret their `prime` and `generator` match, which is fundamental to
the algorithm.

This uses libuv's mkdtemp function to provide a way to create a
temporary folder, using a prefix as the path. The prefix is appended
six random characters. The callback function will receive the name
of the folder that was created.
Usage example:
fs.mkdtemp('/tmp/foo-', function(err, folder) {
console.log(folder);
// Prints: /tmp/foo-Tedi42
});
The fs.mkdtempSync version is also provided. Usage example:
console.log(fs.mkdtemp('/tmp/foo-'));
// Prints: tmp/foo-Tedi42

This commit addresses https://github.com/nodejs/node/issues/5431 by
changing the way that the repl handles assignment to the global _
variable.
Prior to this commit, node sets the result of the last expression
evaluated in the repl to `_`. This causes problems for users of
underscore, lodash and other packages where it is common to assign
`_` to the package, e.g. `_ = require('lodash');`.
Changes in this commit now result in the following behavior.
- If unassigned on the repl, `_` continues to refer to the last
evaluated expression.
- If assigned, the default behavior of assigning `_` to the last
evaluated expression is disabled, and `_` now references whatever
value was explicitly set. A warning is issued on the repl -
'expression assignment to _ now disabled'.
- If `_` is assigned multiple times, the warning is only displayed once.
- When `.clear` is executed in the repl, `_` continues to refer to its
most recent value, whatever that is (this is per existing behavior).
If `_` had been explicitly set prior to `.clear` it will not change
again with the evaluation of the next expression.

`Console` constructor checks that `stdout.write()` is a function but
does not do an equivalent check for `stderr.write()`. If `stderr` is not
specified in the constructor, then `stderr` is set to be `stdout`.
However, if `stderr` is specified, but `stderr.write()` is not a
function, then an exception is not thrown until `console.error()` is
called.
This change adds the same check for 'stderr' in the constructor that is
there for `stdout`. If `stderr` fails the check, then a `TypeError` is
thrown.
Took the opportunity to copyedit the `console` doc a little too.

The current documentation for writable.write only specifies that the
callback is called "once the data has been fully handled". It is
ambiguous whether this means "successfully handled" and, if so,
whether the callback is called if the data can not be successfully
handled (i.e. an error occurs).
The ambiguity is not only in the documentation. The stream class
implementations differ on this point. stream.Writable invokes the
callback with any errors that occur during parameter checking or
during calls to _write. However, not all classes return all errors
to _write. zlib.Zlib does pass argument and state errors to the
_write (_transform) callback, but does not pass data errors.
http.OutgoingMessage passes argument type errors and some other types
of errors, but not all.
This inconsistency is behind issue #1746 and, I suspect, other issues
in client code which passes a callback to write.
This commit takes no position on whether the callback error behavior
should changed, but simply attempts to document the current behavior
in a way that is open to changes so that users are not caught by
surprise.
