Previously, the GAL_DISPLAY_OPTIONS object in FOOTPRINT_PREVIEW_PANEL::New
was passed by reference in the ctor, down to EDA_DRAW_PANEL_GAL, which stored
it as a reference. The object in New() then goes out of scope, so the
referencing panel outlives the options.
Fix this by making a copy in a std::unique_ptr of the options, and giving
ownership to the panel.
There is another issue here: when the Pcbnew options are copies, the
OBSERVABLE subscriber list is copied too. This means if the panel called
NotifyChanged() on the options, Pcbnew would get updates, even though a copy
of the options changed. However, the panel doesn't change the options or
notify, so it's OK for now.
(cherry picked from commit 17e88d0944)
- support for background color setting
- removed several global config settings (such as g_Drc_On)
- wrapped most of global config settings in PCB_GENERAL_SETTINGS class
- reorganized PCB general options dialog to clearly mark which options concern only the legacy canvas
- new GAL feature for legacy users: double-click (or E) to change track width available as an option.

- Pull out compound widget bits into FOOTPRINT_PREVIEW_WIDGET
- Move all pcbnew-specific bits *inside* pcbnew; implementation should
be private for users
- Make a few class members and inner types private
