* Joystick hotplug support (#4141) * use SDL_PollEvent instead of SDL_JoystickUpdate Register hot plugged controller by GUID if they were configured in a previous session * Move SDL_PollEvent into its own thread * Don't store SDLJoystick pointer in Input Device; Get pointer on each GetStatus call * Fix that joystick_list gets cleared after SDL_Quit * Add VirtualJoystick for InputDevices thats never nullptr * fixup! Add VirtualJoystick for InputDevices thats never nullptr * fixup! fixup! Add VirtualJoystick for InputDevices thats never nullptr * Remove SDL_GameController, make SDL_Joystick* unique_ptr * fixup! Remove SDL_GameController, make SDL_Joystick* unique_ptr * Adressed feedback; fixed handling of same guid reconnects * fixup! Adressed feedback; fixed handling of same guid reconnects * merge the two joystick_lists into one * make SDLJoystick a member of VirtualJoystick * fixup! make SDLJoystick a member of VirtualJoystick * fixup! make SDLJoystick a member of VirtualJoystick * fixup! fixup! make SDLJoystick a member of VirtualJoystick * SDLJoystick: Addressed review comments * Address one missed review comment
