Routine Description

    Tests that 'Status' is one of an expected set of error codes.
    Used on debug builds as part of the VALIDATE() macro.

Example:

    VALIDATE( (RpcStatus,
               RPC_S_SERVER_UNAVAILABLE,
               // more error codes here
               RPC_S_CALL_FAILED,
               0)  // list must be terminated with 0
               );

     This function is called with the RpcStatus and expected errors codes
     as parameters.  If RpcStatus is not one of the expected error
     codes and it not zero a message will be printed to the debugger
     and the function will return false.  The VALIDATE macro ASSERT's the
     return value.

Arguments:

    Status - Status code in question.

    ... - One or more expected status codes.  Terminated with 0 (RPC_S_OK).

Return Value:

    TRUE - Status code is in the list or the status is 0.

    FALSE - Status code is not in the list.
