Allow input configuration with SDL joysticks (#3116)
* Add infrastructure to poll joystick input and get ParamPackages * Generalize the callbacks in configure_input.cpp and add buttons for analog sticks * Use the polling classes in the input dialog * Fix includes * Formatting fix * Include real header instead of forward declaring, to fix compiler error * Split up pair and add deadzone for joystick configuration * Pass ParamPackages by reference to callback * fix formatting * getPollers -> GetPollers * Add forward declarations and simplify code a bit * Update joysticks before opening them * Fix mixup between joystick IDs and device indices
