[Nut-upsuser] PR to test for users of Qx devices (blazer and nutdrv_qx)

[Jim Klimov]

Thanks! Now trying to make sense of this :) Partially notes to myself,
partially to whoever might want to peek deeper into the driver... If only
we had some active Qx experts (or wanna-be's)!..

@tbsky:
Can you please check if 2.7.4 also reports the huge voltages for the 3kW
and 10kW units, or something around 13.5V? Does it set "battery.packs" to
20 or 6?
Namely, I wonder if the new "battery_voltage_reports_one_pack" handling
(and with no such option in your configs) misfires here somehow?..

Also, can you please re-run the tests with the PR-ed branch build and
higher verbosity (e.g. `./nutdrv_qx -a ftups -DDDDDD -d1`) to help trace
whether values optionally guessed by qx_initbattery() are in fact guessed
or directly provided by respective devices (and subdrivers)?..

Findings and ramblings:

* the 2kV model is handled by a different subdriver than the other two.
* A "battery_number" ("number of batteries that make a pack") is unique to
drivers/nutdrv_qx_voltronic.c and seems to be in 0..9 range yet the driver
gets a "20" value somewhere (setting? protocol?) It is not further reported
as a dstate value, it seems.
* There are separately "battery_packs" which are 0.99 per comments in the
same subdriver.
* Reported battery voltages seem huge, and maybe scale with the amount of
batteries (comments seem to imply that). I wonder if in fact the driver
should report single-battery (pack) voltages, e.g. (272.9/20)=13,645 and
(82.0/6)=13.67 respectively?..
* Note: To complicate matters more, and as was among inputs for the PR,
some terminology (and devices) deal with "cells" which can make up a single
battery, down to reporting their individual voltages in the 2V range...

So far it seems that for the bigger devices (and their driver) the
"battery.packs" is reported and "known" so there is less guesswork
involved. For the 2kV device it does log some progress through guesswork:

No values for battery high/low voltages
Using 'guesstimation' (low: 10.400000, high: 15.000000)!

Autodetected 1 as number of battery packs [12/13.50]
Battery runtime will not be calculated (runtimecal not set)

and ends up with some possibly measured and some guessed voltages:

battery.charge: 67
battery.voltage: 13.5
battery.voltage.high: 15.00
battery.voltage.low: 10.40
battery.voltage.nominal: 12.0

and probably ends up guessing the charge in qx_battery() if such dstate
value is not yet available (e.g. from device protocol... or if the PR
botched something, e.g. order of reading/guessing somehow):
    batt.chrg.act = 100 * (batt.volt.act - batt.volt.low) / (batt.volt.high
- batt.volt.low);
would be ( 100 * (13.5 - 10.4) / (15.0 - 10.4) ) = 67.39...

Close enough to explain the value seen, at least.
