[openbsd] can't compile, no SEEK_DATA/SEEK_HOLE support

[jirib]

IIUC SEEK_DATA/SEEK_HOLE is not standardized yet, could you meanwhile make it portable to OpenBSD?

Sorry, I missed this issue. I'll have a look when I find some time.

If you have a patch, let me know. I never tested building this with OpenBSD.
