SDL_rwops read/write functions return size_t again

Browse source 
The current status is stored in the SDL_rwops 'status' field to be able to determine whether a 0 return value is caused by end of file, an error, or a non-blocking source not being ready.

The functions to read sized datatypes now return SDL_bool so you can detect read errors.
