[whois_] Plugin to monitor domain registration expiries

This plugin only monitors one domain per instance, but should be easily
extensible to monitor several at once if need be.

Ruby plugins: apply code changes as suggested by "rubocop --auto-correct"

Unify file encodings to UTF8

[plugins/transmission] Fixups for consistency

Use standard colours for the transmission_activity plot (but keep a
darker one for paused torrents).

Also, remove the ${host} from the graph_title, and add it in the
graph_info, for better groupability.

[network/hostsdeny] Refactor to support any blocked service

The HostDenied field is renamed to ssh. To preserve existing data,

1. cd /var/lib/munin/example.net

Merge branch 'fix-autoconf-exitcode'

Various plugins still followed the old (before 2009?) convention of using
a non-zero exitcode for indicating "no". Most of these (obvious) occasions
should be fixed now.

Fix trivial instances of wrong autoconf exitcodes

Whitespace cleanup

• remove trailing whitespace
• remove empty lines at the end of files

fix wrong example-graph filenames

Plugin multibandwidth: unify whitespace

Plugin multibandwidth: rename environment setting for limiting the valid range

Plugin multibandwidth: simplify speed calculation

Update multibandwidth

bing have some random spikes. Added a variable that is used to indicate the maximum value of mbps that can be recorded (in bps).

plugin ipset: use "set -eu"

removed exit

Merge https://github.com/munin-monitoring/contrib

p/if1sec-c: handle absence of state file

olsrd: various improvements

• support dirty config
• add perldoc header
• flake8 and shellcheck clean

wireless_channel_occupation_: move from "network" to "wifi"

plugin multiping_async: move to 'network'; fix filename

Plugin sockstat-via-procfs: fix style issues

added executable permission for multiple plugins

iptables-related plugins: use "-w" for consistent results

The parameter "-w" forces iptables to wait for a lock before
printing data.

The parameter requires iptables 1.6 (released 2015).

See https://github.com/munin-monitoring/munin/issues/586

replace hard-coded paths (e.g. '/var/lib/munin/plugin-state') with '$MUNIN_PLUGSTATE'
