Patches to get Arla running on FreeBSD 8-CURRENT

[Palle Girgensohn]

I'm delighted to see all this chatter about arla. Any chance we can get a 
server working as well? I reckon that should, in principle, be easier, 
since it is not as much kernel involvement, right? But the best bet is 
OpenAFS, and it is different animal, so the KTH guys are not as deep into 
this code?
