[Translator] added additional conversion for encodings other than utf-8

Added an additional conversion if there is another encoding in the
xlf file present. Values from simple_xml are always utf-8 encoded.
Also added some tests to verify this new behaviour.

[HttpFoundation] fixes creation of sub requests under IIS & Rewite Module

There are a few bugs to address.

1. `HTTP_X_ORIGINAL_URL` wasn't removed from the server parameters, so is picked back up [here](https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpFoundation/ServerBag.php#L33) upon recreation of a sub request.
2. When `X_ORIGINAL_URL` is passed in the headers by IIS, `IIS_WasUrlRewritten` and `UNENCODED_URL` can also be passed as server vars, so they must also be removed for sub request URI's to be resolved correctly.

Additionally, I have removed the OS check for windows, because it was only done for 2 out of 4 of the IIS specific checks, and it made the code untestable.

Also added tests for all scenarios as there were none.

fixed detection of secure cookies received over https

BrowserKit's cookie handling only recognises a secure cookie if the
cookie option is set and the cookie was set over an https request.
The client was not passing the url into the cookiejar update code,
causing Cookie::isSecure() to always return false for every cookie.

Fixes symfony/symfony#7666
[HttpFoundation] fixed empty domain= in Cookie::__toString()

[HttpFoundation][BrowserKit] fixed path when converting a cookie to a string

An empty path has a different meaning than a /; it means that the path
is the one from the current URI.

[BrowserKit] fixed detection of secure cookies received over https

As reported in symfony/symfony#7666, BrowserKit's cookie handling only recognises a secure cookie if the cookie option is set and the cookie was set over an https request. The client was not passing the url into the cookiejar update code, causing Cookie::isSecure() to always return false for every cookie.

I have corrected this behaviour and added an additional unit test to prove the bug and fix.
