…ignal Prior to this commit the signal `CClientUIInterface::ThreadSafeMessageBox` is not connected to a slot in Qt at the time its emitted when `-litemode` is used. The signal gets emitted from `InitWarning`, in `InitParameterInteraction`. This happens currently before `BitcoinGUI` gets created by `app.createWindow(networkStyle.data())` in `dash.cpp` where the signal becomes connected to the slot. After this commit the litemode `InitWarning` will be called in `AppInitParameterInteraction` which runs after `BitcoinGUI` has been created, means the signal will be connected then at that point and the crash is fixed.
- Always show a basic warning if `-litemode` gets used no matter if its activated or not. - Let the user know when -disablegovernance gets forced by -litemode.

Prior to this PR the signal
CClientUIInterface::ThreadSafeMessageBoxis not connected to a slot in Qt at the time its emitted when-litemodeis used. The signal gets emitted fromInitWarning, inInitParameterInteraction. This happens currently beforeBitcoinGUIgets created byapp.createWindow(networkStyle.data())indash.cppwhere the signal becomes connected to the slot. After this commit the litemodeInitWarningwill be called inAppInitParameterInteractionwhich runs afterBitcoinGUIhas been created, means the signal will be connected then at that point and the crash introduced in #3579 is fixed.This also brings some changes to the deprecation warning message if
-litemodeis still used.-litemodegets used no matter if itsactivated or not.
-disablegovernancegets forced by-litemode.
