ntlm: Fixed HTTP proxy authentication when using Windows SSPI
Removed ISC_REQ_* flags from calls to InitializeSecurityContext to fix bug in NTLM handshake for HTTP proxy authentication. NTLM handshake for HTTP proxy authentication failed with error SEC_E_INVALID_TOKEN from InitializeSecurityContext for certain proxy servers on generating the NTLM Type-3 message. The flag ISC_REQ_CONFIDENTIALITY seems to cause the problem according to the observations and suggestions made in a bug report for the QT project (https://bugreports.qt-project.org/browse/QTBUG-17322). Removing all the flags solved the problem. Bug: http://curl.haxx.se/mail/lib-2014-08/0273.html Reported-by: Ulrich Telle Assisted-by: Steve Holme, Daniel Stenberg
