    Remove unused variable in pmdagfs2 lock_time_assign_glocks
    
    The "comparator" lock_time variable appears to be left over
    from more care-free times, when locks were locks and glocks
    were the weapon of choice for law enforcement agencies.
    
    Cleaned surrounding code consistency oddities (someday that
    whitespace strategy will make sense to me Paul, it all seems
    fairly random atm though).

commit 8abe02256e47178f47f07ac876b14e0e9f8dd16a

    Re-enable procedure call traceback for pmcd
    
    On badness (segv, ...) pmcd will produce a procedure call traceback
    in the logfile if (a) -Ddesperate is specified on the command line (or
    pmcd.control.debug is set equivalently) _and_ (b) the libc/ld run-time
    supports backtracing.
    
    Used to work on Irix.  Now works on glibc based platforms.

    pmdagfs2: Additional filtering and efficiency improvements
    
    Improved filtering for glock_lock_time metrics by glocks now requiring
    a minimum threshold (currently 25 can be increased) for the dlm and
    queue fields ensuring that the locks chosen have been through the dlm
    the given number of time. We filter only for locks that have been passed
    around a given number of times.
    
    Made changes to the sorting and comparison functions allowing a simpler
    choice w.r.t the worst glock at the given time (also easier to read).
    These changes are in place ready for future improvements (top 10
    glocks etc).
    
    Make some slight changes in the comments to reflect the changes in the
    code and work towards reducing redundant comments.
