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.

It allows to force ipv4 or ipv6 when the DNS returns both addresses, but

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.

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.
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.

: 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:

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

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.

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.
