I like this, but we certainly don't need *three* CredHandles and
CtxtHandles in each auth state. We probably want something like:

struct http_auth_state {
	int state;
	char *challenge;
#ifdef HAVE_GSSAPI
	gss_name_t target_name;
	gss_ctx_id_t context;
#endif
#ifdef _WIN32
	CredHandle sspi_cred;
	CtxtHandle sspi_ctx;
	SEC_WCHAR *sspi_target_name[2];
#else
	int ntlm_helper_fd;
#endif
};

We could even have the GSSAPI stuff and ntlm_helper_fd in a union, in
fact. They don't need to take up *separate* space.
