Fixes: #3301
During my tests and developing with the collectd and so
luci-app-statistics I noticed that the values displayed in the Y-axis
are misleading, because probably the individual values are added
together in each case. So the view is not corrected.

* Frequency usage percentage stats are by kHz instead of Hz.
Correct the labels. (Linux natively uses kHz for CPU frequency stats,
but collectd scales the current frequency stats item to Hz.)
* Show frequency usage percentage graph before the transition counts,
as it is more descriptive.

In original collectd, values of this metric are in range 0-1. OpenWrt
previously have a custom patch scaling them up to range 0-100. That
patch has been removed to align with possibly other deployments.

Add two data series-level options "negweight" and "posweight" that
will use the numerical value of the data instance name
as the sorting factor. This enables e.g. sorting by CPU frequency
in the cpufreq module.
Add new graph-level option "ordercolor" to use colorsfrom a
pre-defined color table for the data series. This enables keeping
similar colors for similar data series in different plugin instances.
E.g. CPU frequencies in several cores that are handled and displayed
separately.
(note: the table has 8 items and if there are more series, it uses
the same colors again. The table can be easily extended/modified)

Collectd 5.9.0 changed the data structure of the cpufreq plugin:
CPU cores are now handled as separate plugin instances.
There are also new data items per core:
* time spent at each frequency
* amount of frequency transitions
Enable these new data items, but initially hide them behind
a new config option "ExtraItems" (default: disabled), as
the amount of graphs in multi-core systems could be rather large.
Note that the frequencies are not (yet) sorted, so the
information value of the time-spent graph is semi-random.

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.

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.

Some graph definitions rely on data not supported across all APC UPSes.
Due to recent upstream changes in collectd, the daemon no longer creates
a NaN-filled .rrd file corresponding to any missing UPS data. Depending
on the connected UPS, this may result in some "broken" graphs on the Luci
Statistics page since rrdtool cannot find the expected .rrd file.
Include the add_supported() function to determine the UPS data available
at runtime and update any definitions of graphs to include only supported
data. For example, the whole chart stack of AC input and output voltages
will normally be "broken" if the UPS only measures AC input voltage. With
these changes, the output voltage graph definition is stripped out,
allowing the chart to render.
Make consistent use of data types and instances in graph definitions. All
definitions now use the same format with the 'instances' key. Unnecessary
'types' and 'sources' keys are removed.
Fix the definition of 'line frequency' graph, based on upstream collectd
apcups plugin code: type is 'frequency' but instance should be 'input'.
This also includes some code and whitespace cleanup.

This patch splits the graphs into 2 graphs.

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.

in 2015.

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.

Clarify the CPU time consumption graph by removing the "idle" data from it.
Especially with light traffic, removing "idle" enables the graph

CPU plugin in the Luci statistics was missing the label definitions,
so the field labels are like "cpu_system" instead of "System".
Add proper label definitions to CPU (like the other plugins already have).
The statistics graph was also missing softirq and interrupt stats, although colors
for them were defined. Softirq consumes massive amount of CPU especially with
any qos in use, so it is important for the user to see also that data. Add both
softirq and interrupt stats to the graph.
