Cleanup on bug 3894 - Fuzzing crashes for SDL_LoadWAV

Browse Source 
Simon Hug

Attached is a minor cleanup patch. It changes the option name of one hint to something better, puts one or two more checks in, and adds explicit casting where warnings could appear otherwise.

I hope the naming of the hints and their options is acceptable. It would be kind of awkward to change them after they get released with an official SDL version.
