Changes the interface as well to remove any unique methods that
frontends needed to call such as StartJoystickEventHandler by
conditionally starting the polling thread only if the frontend hasn't
started it already. Additionally, moves all global state into a single
SDLState class in order to guarantee that the destructors are called in
the proper order
* 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
These functions include reloading udp client, testing communication and configuring calibration. I also added a function to common/thread.h to use WaitFor.
* 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
