This feature is of limited benefit and causes unexpected behaviour on
rigs with lower than 1Hz resolution. Removed for simplicity.

These were using a hijacked custom spin box that was designed only for
letters i.e. submodes. Now there are two new custom spin boxes.
HistedSpinBox:- can be set with a list of integer values which the
step up and down will follow. Optionally limits the maximum and
minimum value to the upper and lower bounds of the values set. Note
that intermediate values are still valid.
RestrictedSpinBox:- more like a combo box because the provided values
are the only ones that can be set.
HintedSpinBox is used for the frequency tolerance and
RestrictedSpinBox is used for T/R period.

Until the advanced band hopping scheduler is upgraded to work with T/R
periods other than 2 minutes this scheduler uses a strictly random
scheduler, except that Tx percentages less than 40 defer Tx periods
that would otherwise be consecutive.

More to come on this but should get Tab 2 basically working with
MSK144 running from a calling frequency.

The wide graph class handles 60m band behaviour of the minimum decoded
JT9 DF internally without leaking implementation details.
On 60m the lowest JT9 DF is always zero and the spin box to set it is
disabled. This reflects that 60m only has narrow channels and JT9
signals should share the same dial frequency as JT65 signals.

Ctrl+M (Cmd+M) was being used as a menu shortcut and in key press
event handlers which leads to inconsistent behaviour on some
platforms. Removed menu action shortcut.
Also tidied up handling of the hide controls menu action by making it
a checkable action and using its checked state to store the control
hiding state.

1. Level meter range increased to 0-90 dB.
2. Level meter reading is independent of slider setting.
3. For a trial period: thermometer bar goes red if a 16-bit sample
is within 5 dB A/D limit.
4. Slider can be used to adjust levels sent to waterfall.
5. Tx6 message is selected on program startup.
Thanks to W9MDB for most of this code.

"JT65 nnnn JT9" blue line to 0 Hz. Now it also moves the spinner to
0 Hz, as it should have done. Subsequent QSY to another band will reset
the blue line and spinner to where they had been, before the QSY to 60 m.
Thanks to W9MDB for this patch.

Use a header format for polynomial coefficients that includes the
valid X range in scaled terms and a count of the number of
coefficients.
Use double precision consistently for polynomial coefficients. This
includes formatting with sufficient DPs when writing to files.
Many changes to the equalization plots, more to come.
Add error handling for reading coefficient, plot and filter
files. This includes being backward compatible for old format
refspec.dat files with no header.

This builds on the static phase compensation in the MSK144 decoder and
the phase analysis and polynomial fitting capabilities also in teh
MSK144 decoder, by allowing captured data to be selected for phase
equalization from the WSJT-X UI.
Reads captured phase compensation curve estimate files containing
fitted polynomial coefficients and measured phase data from MSK144
receptions. Intent is to select a compensation curve that is from a
known transmitter like an SDR which have good phase linearity. Phase
plots and compensation polynomials may be viewed and compared with the
current compensation polynomial. A suitable polynomial can be applied
to be use in all further decoding of MSK144 signals.
Plots of the currently selected polynomial and its modified higher
order terms polynomial which is actually used in equalization (this
plot may be dropped - it is just for kicks at the moment). When a
captured phase analysis file is loaded plots of the measured phase and
the proposed best fit polynomial are shown.
Basic maintenance is also included allowing clearing and loading
captured plots and an option to revert to a flat no equalization
curve.
More to come on this as amplitude equalization is also possible, this
will probably be similar, maybe even plotted on the same graph with
dual axes for phase and amplitude. Amplitude correction from a
measured reference spectrum could be viewed and selected for
equalization for all modes. TBC...
This change also introduces the QCustomPlot 3rd party
widget. Currently this is statically linked from a qcp library built
by the WSJT-X CMake script. This will probably be migrated to a shared
object (DLL) build as a CMake external project, once some CMake script
re-factoring has been completed, which is more in line with the
QCustomPlot author's intentions. This will allow efficient reuse in
other tools shipped with WSJT-X.

Allow band drop down list to be used to select FreqCal frequencies,
also resets position in automatic cycle. Tidy up some unnecessary
code.

1. Menu item *Tools -> Execute frequency calibration cycle* is renamed and checkable. Cycling does not start until checked.
2. Ctrl+F10 now allows you to cycle manually through the list of calibration frequencies.
3. Calibration sequence lengths can be set to 5, 10, 15, or 30 s with the sbTR spinBox.
Also: don't set sbTR index to 0 when entering a slow mode.

Some default time signals have been added to the frequency list so a
base set can be obtained by resetting the frequency list,
alternatively they can be added ad hoc in the normal fashion.
FreqCal mode behavior is to select the lowest cal frequency upon
entering FreqCal mode and cycling through each cal frequency
repeatedly. Ctrl+F10 jumps directly to the next higher frequency.
