in SDL2 SDL_ThreadID() was a function that's now
SDL_GetCurrentThreadID(), but in SDL3 SDL_ThreadID is a type, so
in C++ `x = SDL_ThreadID()` is valid code (default constructor which
in case of integers means 0), so that's a massive footgun.
See the big comment in SDL_oldnames.h for more details.
Added `#undef SDL_ThreadID` in SDL_dynapi.c because it has one of the
(quite rare) cases where "SDL_ThreadID" followed by a "(" is actually
correct and necessary (function pointer returning SDL_ThreadID).
Simple DirectMedia Layer (SDL for short) is a cross-platform library designed to make it easy to write multi-media software, such as games and emulators.
