Gerald Carter 0d6352da48 r7995: * privileges are local except when they're *not*
printmig.exe assumes that the LUID of the SeBackupPrivlege
  on the target server matches the LUID of the privilege
  on the local client.  Even though an LUID is never guaranteed
  to be the same across reboots.  How *awful*!  My cat could
  write better code! (more on my cat later....)

* Set the privelege LUID in the global PRIVS[] array

* Rename RegCreateKey() to RegCreateKeyEx() to better match MSDN

* Rename the unknown field in RegCreateKeyEx() to disposition
  (guess according to MSDN)

* Add the capability to define REG_TDB_ONLY for using the reg_db.c
  functions and stress the RegXXX() rpc functions.
