6e452ac6dc Plugin lxc: remove fieldname compatibility attempt with double underscores 
The attempt of compatibility (introduced in c0fe6dc3c) did not work,
since the previous implementation *replaced* the first character
(if it was invalid - e.g. a digit) instead of prepending an underscore.

858f3e3af4 Plugin lxc: rename to "lxc_guests" 
The plugin handles details of LXC guests.  Thus we should leave the
remainder of the namespace to other plugins.

3ebcb8b550 Plugin lxc: remove reference to framagit repository 
Plugins maintained within the contrib repository of munin should not
refer to other locations as their primary source.
(otherwise they should be maintained in that primary source and not in
the contrib repository)

3f8ef105ff Plugin lxc: enable "set -eu" for better error handling 
The code should be suitable for "exit-on-error" and "error-on-unset".

856572ad9b Plugin lxc: verify the availability of "lxc-ls" 
Previously "autoconf" only verified, that /var/lib/lxc exists.  But this
could be just a remainder of a formerly installed lxc package.

f00f28cf6f Plugin lxc: use functions for top-level activities 
This clarifies the flow of control and allows to use
MUNIN_CAP_DIRTYCONFIG later.

4356a024a7 Plugin lxc: clarify name for function "active_guests" 
Previously a variable and a function used the same name.
This was no problem, but it can cause confusion.

55b881878c Plugin lxc: change the plugin from "bash" to "sh" 
No more bashisms were left.

6bb4719881 Plugin lxc: separate function for title beautification 
This avoids a bashism.

8b955667c5 Plugin lxc: fix handling of "excludes" parameter 
Previously only the first item in the "excludes" environment variable
was really excluded.

276e96c0dd Plugin lxc: remove ineffective "sort -u" from function "active_guests" 
The output of "lxc-ls" is not line-splitted.  Thus all active guests
are printed in a single line and "sort -u" (removal of non-unique
entries) had no effect.

The "U" value is not defined for the "max" field.

0d593014b4 Plugin lxc: fix printing of "${graph_period}" 
This specific text token ("${graph_period}") is interpreted by munin and
should not be interpreted by the shell.  Thus it needs to be escaped.

e91f7ecba7 Plugin lxc: remove ineffective usage of "bc" 
The command "wc -w" already outputs the final result.
Thus we do not need this command (and do not have to depend on it).

ec3a7f4045 Plugin lxc: function "lxc_count_processes" now outputs its result 
Previously the result was returned as the exit code of the function
(which would prevent the usage of "set -e").
Additionally the fallback value that was previously calculated outside
of the function is now part of it.

9af96d2c60 Plugin lxc: draw stacked RAM graphs by default 
Previously "ram_display_stacked" defaulted to "false" (non-stacked
graphs).  The new default should be suitable for most situations.

ab6f4e3c6e Plugin lxc: fix configurable RAM graphing 
Previously (before the multigraph conversion) the configuration setting
for "lxc_ram" was called "areastack".  The multigraph conversion
documented a new configuration setting "ram_areastack", but it was not
used, yet.
Thus we can switch to a more descriptive name: "ram_display_stacked".
