switch UFS -> UFS2

[dark0s Optik]

Hi all, I'am newbye about this OS.
I'd like to achieve this point found in DragonFly project page:

-  Bring in support for UFS2, just the changes to extend the width of
some fields from 32 bits to 64 bits.

I'd like know I can try programming for DragonFly and how can I find
requested source for DragonFly and FreeBSD.

thanks,
saverio
