workaround for BITS

These are credentials for the proxy, so on a private computer this should not
be a problem. I'd expect the SSPI doesn't need to be used in BITS directly but
in a lower level library. We currently use urlmon, however so far I haven't
found APIs to choose the method of authentification (e.g. basic vs digest) or
http file upload. AFAIK lower-level libraries like wininet or winhttp supports
it. But it's possible that urlmon also provides some obscure interfaces to
support it.

The installer needs two more functions from BITS. With this patch that makes
them return S_OK it downloads the file, but then fail because of unimplemented
crypt32.CryptMsgGetAndVerifySigner. I don't know how hard it is to implement.

Ramiro: this bug is about version 2005. For version 2008 you should create
another bug - it's possible it will be harder to fix than 2005.
