Query the PlutoSDR hardware for the current RX gain range and use it
to configure the GUI gain control dynamically.
The AD936x gain limits vary with LO frequency. Previously the GUI used
a fixed gain range, allowing users to select values that the hardware
would reject after changing bands. The gain slider now refreshes its
minimum, maximum, and step size whenever the device center frequency is
updated.
Also change the gain setting serialization to use a signed integer so
negative gain values are preserved for operating modes that support
them.
Changes include:
- Add DevicePlutoSDRBox::getGainRange() to read
in_voltage0_hardwaregain_available.
- Expose gain range through PlutoSDRInput.
- Refresh GUI gain limits when the device frequency changes.
- Avoid unnecessary widget updates when limits are unchanged.
- Store/restore gain as a signed value.
- Add default RX gain limit constants for fallback when the device
cannot provide its range.

screen when screen orientation changes.
Add DialPopup to allow dials to adjusted with a slider, which is easier
on touchscreens.
Add TableTapAndHold to support table context menus on touchscreens.
This will use the RF bandwidth from the device, which is different
between AD9363 and AD9364.
Things are now managed like the device likes - analog low pass bandwidth
is RF (complex) bandwidth, not baseband single I or Q bandwidth.

When updating firmware, the devices which have AD9364s on them, get
reset to the default of a AD9363 (tuning range of 325 to 3800 MHz).
SDRAngel assumes a AD9364, and the GUI allows you to set LO settings
that the firmware doesn't support.
This ensures that does not happen, by going out to the hardware, and
querying the device to set the min/max limits on LO.
