Update to version 2.6.0

* Sort threads within process.
* Individual threads within a process (key 'y') are shown in the
  order of their TID. With the additional key 'Y' threads within
  a process are sorted based on the current sort criterium.
* Show the WCHAN per thread.
* With the key 'W' is active, the wait channel is determined per
  thread and shown with the scheduling information (key 's').
* Show runqueue delay per thread/process.
* For every process (cumulated) and every thread the time spent
  waiting on the runqueue is shown as value 'RDELAY'.
* Show other modified/new metrics:
  + PSI pressure during interval time is shown
  + Counter 'avio' (average I/O time) for fast disks in
    microseconds or nanoseconds
  + Counter 'zfarc' showing the current size of the ARC (cache)
    for ZFSonlinux
  + Counter 'swcac' showing the current size of the swap cache
  + Counter LOCKSZ showing the virtual locked memory size
* Avoid crash with very high load average values.
* Fix errors in reading InfiniBand states.
* Support of rawlog files spanning multiple days.
* The time specification to define the begin time (-b flag)
  and end time (-e flag) of both atop and atopsar is
  [YYYYMMDD]hhmm now
* This also applies to the branch key ('b') when using atop
  interactively.
* Support reading rawlog from a pipe.
* Rawlog data can be read from a pipe by atop and atopsar with
  the option '-r -'. In this way, concatenated rawlog data from
  the command atopcat can be directly processed.
* New program atopcat, the program atopcat concatenates rawlog
  files and writes this data to stdout. The output can be
  redirected to a new rawlog file or to atop/atopsar directly
  via a pipe (see option '-r -' of these commands).
  In this way e.g. weekly or monthly reports or extractions
  can be created.

Update to version 2.5.0 

Modifications for atop:

* Avoid using perf counters in VM
  New option 'perfevents' in the atoprc file to define if the Instructions
      Per Cycle (IPC) should be retrieved via the 'perf' counters. Specify
      value 'auto' (default), 'enable' or 'disable'. In case of 'auto', the
      Instructions Per Cycle counter will not be retrieved on VMs due to the
      overhead of reading this counter in a guest.
* Improve daily rotation of logfile for systemd-based systems.
  Exchange the files /etc/cron.d/atop, /etc/logrotate.d/psaccs_atop,
      /etc/logrotate.d/psaccu_atop, /usr/share/atop/atop.daily,
      /var/log/atop/dummy_after and /var/log/atop/dummy_before by
      atop-rotate.service and atop-rotate.timer.
* Bug fixes:
  Correction of PSI value 'io full'.
  Use smaps_rollup (if present) instead of smaps for better performance.
  Use writev instead of 3 single writes to avoid logfile corruption.
  Modified handling of error messages (remain visible after window is
      closed).
  Correct CID for containers created by Kubernetes.
  Allow reading a logfile via a named pipe (non-seekable).

Modifications for atopconvert:

* Show version of input file (even if only one parameter specified).

General:

* The format of the raw file is compatible with version 2.4.
