[ros-kernel] Patch to implement NtCreateToken()

[Joseph G. <gal...@va...>]

I've implemented NtCreateToken and fixed up
NtQueryInformationToken().

- Implement NtCreateToken()
- Implement RtlGetAce()
- Fix bug which cause RtlCreateAcl() to always fail.
- Cleanup parameter names and fix bug that caused a
  buffer overrun in RtlCopySidAndAttributesArray()
- When referencing the token object in NtQueryInformationToken()
  pass in either TOKEN_QUERY access or TOKEN_QUERY_SOURCE access.
  Passing in zero led to ObReferenceObjectByHandle() always
  failing with ACCESS_DENIED.
- Fixed NtQueryInformationToken() to check the buffer
  length and return STATUS_BUFFER_TO_SMALL and the
  required length.
- Ensure that the ReturnLength is set correctly when
  NtQueryInformationToken() succeeds.  Previously, it
  was set to the number of bytes unused in the user buffer
  in some cases or not set at all.
- Handle case of NULL default dacl correctly in
  NtQueryInformationToken()
- Update main makefile to build apps\utils.
- Update makefiles in apps\utils to have the
  correct PATH_TO_TOP.
- Update main makefile to build apps\tests\tokentest

I'm not sure how to go about submitting this
code for checkin.

I've included the output from cvs diff; I'm
not sure if that is good enough or not (I'm
definitely not a patch / diff guru.)

Also included is tokentest.c and a makefile which
need to be added to the apps\tests\tokentest
directory.

Let me know what else I need to do.

Thanks,

Joseph
