http NTLM: Tidied up more inconsistent spacing.
Moved NTLMSSP_SIGNATURE, HOSTNAME_MAX, SHORTPAIR and LONGQUARTET definitions in ready for move to curl_ntlm.c. Used separate variables for Windows SSPI and native code to ease moving of code to curl_ntlm.c. Fixed typographical erros where SPPI should be SSPI. Fixed compilation warnings on 64-bit builds when calling Windows SSPI functions.
