[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.
