commit 73f52eb43a66f78c21bd8e61bd25f63415f396f0
Author: Dave Brolley <brolley@redhat.com>
Date:   Mon Jan 30 13:40:16 2012 -0500

    PR 13631 and other rework of multi-privilege level support
    
      - PR 13631 - Detection of Reqested Privilege Level in stap-server
        - Parsing of the client's command now uses getopt_long and shares
          the getopt input with session.cxx
          - cmdline.cxx, cmdline.h
      - Do not allow multiple privilege-setting options to specify
        different privilege levels.
      - No longer a need for stap-serverd to generate a --privilege
        option for the spawned stap.
      - stap-serverd cannot (and no longer does) rely on knowledge of
        the highest signed privilege level when evaluating the user's
        credentials.
      - Simplified user credentials test against those required by the module
        in stap-serverd.
      - Some kernel.* probes were being registered for use by stapdev only.
        Corrected to be stapdev | stapsys.
        - Corrected testsuite problem which was hiding this bug.
