Generate better Acct-Session-Id

    The current code generates Acct-Session-Id based on the current time.  However, some systems without real-time clocks always have the same time when they boot.  So the Acct-Session-Id values were getting re-used.

  The patch uses os_get_random(), or if that fails, the does an exclusive-or of the time in seconds and microseconds.  There microseconds are likely to vary somewhat, even on systems with no real-time clock.
