With some apache + php-fpm setup we need to set ```PHP_AUTH_DIGEST``` value if not already setted in GLOBAL vars.

Added some unit tests too.

What is this?
----

_Note to reviewer: This follows on from a previous pull request: https://github.com/symfony/symfony/pull/8184
Since the introduction of `Request->setTrustedHosts()` — the implementation of this fix has been simplified._

This fixes the semantics of the `Request#getPort()` method to prefer the HTTP_HOST header over SERVER_PORT.

This is relevant in situations where the web server is running on a different port to the public facing website. e.g. load balancers, proxies, port forwarding.

Consistency
----

This change makes Symfony more consistent with other popular web frameworks.

Preferring HTTP_HOST over SERVER_NAME and SERVER_PORT is the strategy used by Ruby's Rack and Python's Django.

Python has a PEP that describes how to reconstruct URLs:
http://www.python.org/dev/peps/pep-0333/#url-reconstruction

[Process][2.2] Fix Process component on windows

This PR fixes Process on windows (almost, see note below).
 - Some unit tests were not Windows compatible
 - Use a file handle for STDERR as well as STDOUT to avoid blocking
 - Decouple pipes and descriptors from Process

As this move some a part of Process in a sub class, I hope merging this in 2.3 and master would not be a PITA. I'm here to make some adjustments after theses merge if needed.

**Important note** :

We are using file handles instead of streams for `proc_open` pipes as described in the code (see [PHP bug #51800](https://bugs.php.net/bug.php?id=51800)). Unfortunately, this workaround may produce corrupted output/error output in some race conditions. That's why `AbstractProcessTest::testProcessPipes` randomly fails when using file handles (on unix and windows).
