Enumerate a directory through a callback function.
This function provides every directory entry through an app-provided
callback, called once for each directory entry, until all results have been
provided or the callback returns either SDL_ENUM_SUCCESS or
SDL_ENUM_FAILURE.
This will return false if there was a system problem in general, or if a
callback returns SDL_ENUM_FAILURE. A successful return means a callback
returned SDL_ENUM_SUCCESS to halt enumeration, or all directory entries
were enumerated.
