The Voltage graph combines Battery, Input Voltage and Output Voltage.
The Y-Axis scale masks changes in Input/Output voltages over time.
This patch splits the graphs into 2 graphs.
This makes it possible to see variations in AC Input/Output voltages.

OpenWRT/LEDE support for APC UPSes is only partial: although the collectd
apcups plugin is included, related lua/luci code is missing. These changes
add the lua side and have been used for ~2 years, both on OpenWRT and LEDE.

Reworked from patches submitted by James Klaas to the luci development list
in 2015.

A missing or faulty luci_statistics config file may prevent
LuCI access completely already at the login phase as
the statistics config is parsed already then.

The error is like:
  .../statistics/datatree.lua:16: attempt to index upvalue 'sections' (a nil value)

User may be completely locked out of LuCI until he figures out
the need to have a proper luci_statistics config file.

Prevent the error by checking for the existence of
the uci config sections before trying to use values from them.

Commit 39ff0538

 accidentally removed the conffiles definitions
from luci-base, statistics, splash and diag-devinfo apps.

That has caused existing config files to get overwritten if the
package has been reinstalled via opkg. Additionally, the splash
text files have not been saved in sysupgrade or backup as they
are located outside /etc/config

This commit adds back the conffiles definitions to the respective
packages.

Introduce option that enables the user to select max values
instead of averages for graphs if the user has disabled RRAsingle.

The option defaults to average values, which have been the default
in Luci statistics.

With rrdsingle the average values are used for graphing. As the
timescale increases (say over a day or month) the average values
progressively reduce.  Using the maximum value over the longer periods
is arguably no less deceptive but it does produce more informative
graphs.

Remove the usually empty standard deviation graph from the ping page.

The graph is empty for most users as collectd measures standard deviation
of individual pings inside the general interval of statistics collection.
Default setting for both ping interval and general collection interval
is 30s in Luci statistics, meaning just 1 ping per interval, which
leads to empty graph.

(To provide relveant data, the ping interval should be 1/4-1/5 of the
general collection interval. Even then the graph does not look very
informative due to different scaling than the latency graph.)

Note that this commit does not change collectd itself, which continues
to collect and calculate also the std.dev. data, which can be fetched
with 'rrdtool' if needed.
