Same as #1381 but with doc and test.

I'm wondering if StreamHandler::createStream is the right place to through exception if we try to use NTLM with PHP Stream.

Something like:

        // Microsoft NTLM authentication only supported with curl handler
        if (isset($options['auth'])) {
            if (is_array($options['auth']) && isset($options['auth'][2])) {
                if ('ntlm' == $options['auth'][2]) {
                    throw new \InvalidArgumentException('Microsoft NTLM authentication only supported with curl handler');
                }
            }
        }

Or in Client::applyOptions ?

Thanks for your contribution.

Can you please squash your commits (and rebase from master)?

Merge branch 'master' of https://github.com/guzzle/guzzle

This shouldn't be there

Since in Client::applyOptions you don't know about the handlers, I would rather do it in StreamHandler::createStream. Options are normalized there anyway (eg. on_headers callback is checked there).

I would also move all the conditions into one if: same amount of logical expressions to evaluate, but less branching and more readable code.

Do you think you can finish this @miguelbalboa ?

@sagikazarmark
squashed and added NTLM Exception in StreamHandler::createStream.

@sagikazarmark do you know when this will be merged?

I don't have an exact ETA yet. Current aim is to get 6.3 around end of February.

Thanks for your work on this, sorry for the painfully long wait.
