Implement NTDLL's CSR routines in a compatible way. Fix prototypes, argument count, deprecated functions and new functions. Some functions will not work (or are designed not to work) fully until the new CSR is committed, but they keep the same functionality as the previous versions (no regressions found; tested with cmd, cmt, putty, telnet, ps). Also added NtSecureConnectPort.
