Changelog since v0.13.0:


- Batch mode: Try to estimate the total runtime of a batch and print it
  before executing the batch itself.

- GUI: Add support for pinning a metadata item open when flipping
  between tabs, and support adding columns to the open files view from
  the metadata view. Both functions are available from the context menu
  when right-clicking in the metadata view.

- Add test mixins to a bunch of tests making it possible to
  simultaneously capture qdisc stats and/or CPU stats of one or more
  hosts while the test is run. This works by setting the test parameters
  qdisc_stats_hosts, qdisc_stats_interfaces and cpu_stats_hosts to
  comma-separated lists of hosts and interface names. The functionality
  relies on the tc_iterator and stats_iterator helper scripts.

- Add a C implementation of the tc_iterator helper script that works on
  OpenWrt and also gives higher polling accuracy than the shell script.

- Add a kill_timeout setting for runners in test definitions which will
  forcibly kill a subprocess after an interval (if it hasn't exited
  already).

- Add the tcp_upload_1000 test for seriously overloading things. On most
  systems, increasing the ulimit is necessary to run this test.

- Support globbing selectors in plot configuration when specifying
  datasets for a plot.

- Record number of failed runners (non-0 exit status) as a metadata key.

- GUI: Fix bugs in plot blitting on older matplotlibs, fix test running
  without a pre-set HOST, fix bugs in draw cache handling, and restore
  the GUI to a working state on Windows.

- Various bugfixes.
