Unlike iOS and macOS, tvOS does not have any persistent local storage. In fact, the ApplicationSupport directory pointed to by the existing Cocoa GetPrefPath() throws an error whenever any attempt is made to access it. To get any local storage on an Apple TV, our only option is to use a temporary cache directory.
This patch changes the tvOS PrefPath to this cache directory and also logs a critical warning that this if developers want their save data to persist across game sessions, they must use some form of iCloud storage.

we use SDL_GetPrefPath() in Chocolate Doom to get a reasonable directory to save and restore config files and savegames:
https://github.com/chocolate-doom/chocolate-doom/blob/sdl2-branch/src/m_config.c#L2162
However, since there is no "organization" behind Chocolate Doom and there is really only one "product" called Chocolate Doom, we pass an empty string for the org parameter and the package string for app.
This leads to two consecutive slashes in the path returned by SDL_GetPrefPath() like this:
/home/user/.local/share//chocolate-doom/
While this is harmless, it sure looks bad.
I believe that it should be possible to either pass a NULL pointer for the org parameter or at least have the function detect an empty string as a means to express "there is no origanization, just a single product". The generation of the path string to be returned by the function will have to get adapted accordingly.

This patch replaces all use of NSAutoreleasePool with the Apple recommended @autoreleasepool. @autoreleasepool is supposedly more efficient, and since it is scope based it can't be accidentally not released.

The recommended way of getting a file name that POSIX file APIs can open in OS X when using an NSString is -[NSString fileSystemRepresentation]. However, the current filesystem API in hg uses -[NSString UTF8String].
- also adds OS X specific magic for bundled apps adding an Info.plist property of name SDL_FILESYSTEM_BASE_DIR_TYPE to the following values will change the bahaviour.
* bundle -- use the bundle directory e.g. "/Applications/MyGame/Blah.app/"
* parent -- use the bundle parent directory e.g. "/Applications/MyGame/"
* resource -- use the bundle resource directory (default) e.g. "/Applications/MyGame/Blah.app/Contents/Resources/"
