Add option to not send a Negotiate headers

If negotiation was attempted but failed do not send a new Negotiate header.
Useful when only one single sign on mechanism is allowed and to avoid
misleading login prompts in some browsers.

Added a test of the GssapiDontReauth option to the test suite.
Also added SPNEGO no auth test.
