Tests case for whitespace in HTTP headers

After some research for bug #17914 it seems that HttpAddRequestHeaders()
doesn't parse correctly headers regarding to whitespace. Some whitespaces are
not removed.

Additionnaly, I found that wininet.dll from IE8 doesn't allow retrieving some
headers with HttpQueryInfo() if they have whitespace in them, while wine does.

Here is a patch which add some tests for whitespace. Thoses new test works with
wininet.dll from IE8.
