Plugin snmp__synology: fix code style issues reported by flake8

Remove plugin solr

The plugin saw only one substantial commit (its initial addition to the
repository). This very first version of the plugin was already broken
(undefined variable "core1") and was never fixed.
Thus it feels sane to assume, that the plugin was never used.

Plugin solr4_: format perldoc header

Plugin tor_: fix code style issues reported by flake8

tests: enable shellcheck for shell-based plugins and flake8 for python-based plugins

Many plugins are still failing these tests.
These expected failures are listed in a file
(t/test-exception-wrapper.expected-failures)
A wrapper script is used for running the tests and comparing the result...

travis: add more missing packages

asterisk: the confbridge graph is in the wrong category

This was a copy/paste error that slipped by unnoticed :\

asterisk: use eq instead of == for comparing a variable to a string

sumpfralle suggested this change on github, since the comparisons are
meant to be string comparisons.

asterisk: change tabs for spaces for indentation

the plugin currently has inconsistencies with how lines are indented:
some lines only use tab characters while all other lines use spaces.
Let's make the coding style more uniform by using spaces everywhere.

asterisk: Add configuration options to disable conference graphs

Since the MeetMe application is not available anymore on Debian, it
makes no sense to keep the graph around. We do however want to keep code
around for parsing stats from MeetMe. So we'll add two "binary" flags...

Revert "Plugin pacman_pending_updates: switch to /bin/sh; update version"

This reverts commit c9cc2f27f6f80526ed9b844adc87fe16502253da.

Actually, it depends on a bashism at line 53:
if hash checkupdates >/dev/null 2>&1; then

plugins: another round of defined(@array) fixing

Plugin pacman_pending_updates: fix and clarify conditionals

The "checkupdates" compound statement (" ... || ... && ...") did not
work due to the equal precendence of both operators (introduced in
6cb5c9e104d9a1a95adba7ce6e97651232c3595e).

Remove quotes in plugin env parameters

Setting
`env.torconnectmethod 'port'`
leads to the error:
```
munin-run tor_bandwidth
env.torconnectmethod contains an invalid value. Please specify either 'port' or 'socket'.
```
Removing the quotes solves that, because the quotes are part of the variable value....
