[00/37] More lustre patches from obdclass

Message

These patches are all a result of my reading of obdclass code,
though some of them extend will beyond obdclass.
One has been posted already but was buggy, another few replace
an earlier patch which, as James pointed out, didn't really
go far enough.

I've done some testing (and found a bug) but haven't completed a full
test run yet.  So both comments and testing most welcome.
