ntlm: Added separate SSPI based functions

In preparation for moving the NTLM message code into the SASL module,
and separating the native code from the SSPI code, added functions that
simply call the functions in curl_ntlm_msg.c.

+* Curl_sasl_create_ntlm_type1_message()

+*
+* Note: This is a simple wrapper of the NTLM function which means that any

+*
+* Parameters:
+*
+* userp   [in]     - The user name in the format User or Domain\User.
+* passdwp [in]     - The user's password.
+* ntlm    [in/out] - The ntlm data struct being used and modified.
+* outptr  [in/out] - The address where a pointer to newly allocated memory
+*                    holding the result will be stored upon completion.
+* outlen  [out]    - The length of the output message.
+*
+* Returns CURLE_OK on success.
