Use PhysicsFS about raceintospace

This would now let us discard src/game/platform_windows/dirent.{c,h} as well as a bunch of CMake tests.

I'm getting some mysterious unhandled exception of "no such path". Appears to be thrown from physfs. Has the media structure changed in a way I need to adapt?

[willglynn]

Right now, it's expecting the game data directories to be right next to the executable. Is that customary on Windows?

[kiyote]

I was using the BARIS_DATA variable, previously.

[kiyote]

Where is it expecting the game data to be in relation to the executable now? Same folder? So:
+raceintospace.exe
+\gamedata
+\images
+\audio

etc?

[willglynn]

Yep. At least, that's my understanding of what it's looking at on Windows. The relevant code is in Filesystem::init().

[kiyote]

Has the gamedata structure changed at all. Still getting a "no such path", I'm just wondering how one is supposed to indicate to the game where all the gamedata is now?

[willglynn]

No, the game data structure hasn't changed. There's also no way to indicate a game data search path at present -- I didn't think this should be necessary, since there are customary locations to put game data on each platform that don't require runtime configuration. On Windows, it should be using the executable's parent directory as the start of the search path.

Huzzah, success. Playing with the BARIS_DATA and BARIS_SAVE environment variables got me moving again.
