Fails to compile on win32

[ctron]

Trying to compile, with defaults enabled, fails on windows:

Having:

xattr = "1"

Results in:

Hm. I didn't really consider windows when I made this crate. I'll see what I can do but it could be a while till I get to it.

[damooo]

It would be helpful to have windows support too, so that one can use same abstraction for native apps.

[Stebalien]

So, I can't support windows as extended attributes aren't a thing there (NTFS has "alternative streams", which is quite different). However, I can let the platform be treated as supported.

I'll bump the priority on this, but, if you have time, a patch would be appreciated.
