Added some extra info to help RetroPie's auto-configuration scripts by exporting the joystick Vendor and Product IDs, which should help with RetroArch's joypad profile generation.
Since 2.0.14, SDL's joystick name (
SDL_CreateJoystickName
) is a normalized version of the name reported by the OS (culled consecutive spaces, trimming trailing spaces, renaming known joystick names like Xbox/PS). This breaks the input auto-configuration scripts in RetroPie, which generate a config with new name, while the emulators/ports expect to find the OS reported name (e.g. RetroArch - see #3398 [1] for an example).This issue is affecting especially PC users, which are not using RetroPie's (old) SDL version and who's RetroArch configuration is incomplete.
Using the Vendor/Product ID would help these situations and support the new SDL versions when added to RetroPie.
