missing rewinddir()

[bucanero]

Right now you can call rewinddir() in your code but it does nothing.
from what I saw, we are missing the rewinddir() implementation. PSL1GHT provides opendir(), readdir() and closedir() based on SCE openDir(), ReadDir() and CloseDir().

Is there a way to provide rewinddir() under PSL1GHT even if we don't have a PS3 syscall for it? I'm thinking about some emulated version but I'm not sure if it's actually possible.
