It allows to force ipv4 or ipv6 when the DNS returns both addresses, but
only one works (for example if there is no ipv6 connectivity).

Update Spanish translation

Signed-off-by: Franco Castillo <castillofrancodamian@gmail.com>

This change splits the graph into two graphs like in apcups and makes it so
possible to see variations in AC Input/Output voltages. Battery charge and
load are indepentent variables. This change also overlays them and display
them as simply two lines. Battery temperature is also displayed as a line now,
as an area under a temperature line makes no sense. Also removed some empty
lines.

Closes: #2417

Fixes: bab4a3ef ("luci-app-statistics - allow rrd files to contain :")
Signed-off-by: Jo-Philipp Wich <jo@mein.io>

Fixes situations where RRD file name contains ":" (eg. _ping/ipv6_) in `rrdtool` it's unescaped - thus not able to render image. Adding simple escaping of `:` to `\\:` fixes the situation.

Might be a solution for #958.

Add the item callback function to the rrdtool definitions.

Signed-off-by: Florian Eckert <fe@dev.tdt.de>

This change defines the menu entry for the LuCI and the rrd definition in
one place. This also has advantage when plugins are written with
exec/python/perl or lua. The controller does not have to be touched for
the menu entry change.

The Diskfree (df) plugin could also collect the values in percent if the
option "ValuesPercentage" is set in the collectd configuration.
This commit will check if "df_complex" / "percent_bytes" or both are
collected by collectd and so will show the corrsponding graph.

[ Fixed too wide line lengths with i18n-sync.pl ]

: is used to delimit fields in DEF: rrd instructions, so when it appears
in a filename it must be escaped using \.[1]  This commit adds the
escaping.

I discovered the issue after configuring collectd-mod-ping to monitor an
IPv6 host (2001:19f0:5:727:5b56:205d:ff55:2208).  Accessing
https://192.168.0.1/cgi-bin/luci/admin/statistics/graph/ping would cause
the following messages to be logged:

    Wed Nov 14 23:04:33 2018 daemon.err uhttpd[30261]: ERROR: can't parse DEF '2ping_avg_raw=/tmp/rrd/openwrthost/ping/ping-2001:19f0:5:727:5b56:205d:ff55:2208.rrd:value:AVERAGE' -2

and the graphs would not display.  After applying this commit, the
graphs display correctly and no messages are logged.

Thanks to a recent commit, the translation files will now
have info about locations where the string is used. That
can help is deciding the correct translation, as all contexts
are more easily found.

Since commit f6bfac21

 ("luci-mod-status: rework iptables status page"),
nothing in luci-base depends on the iptparser class anymore, so fold it
out into a separate package and let the few apps that require it depend
on the new library package.

Saves about 10K uncompressed in luci-base while the iptables status
rework enlarged the markup by roughly 5KB, saving roughly 5KB of size
overall.
