vnode locking

[Peter Werner <peterw_(_at_)_ifost_(_dot_)_org_(_dot_)_au>]

there is a diff converting openbsd fs's to do vnode locking like netbsd
available at http://www.ifost.org.au/~peterw/new-vlock.diff (~140k). its
diff'ed off -current updated this morning. 

back up your vnode_if.src, add option NEW_VLOCK to your config and 
remove option LOCKDEBUG if you had it. it hoses vnode_if.src, i dont 
know awk but will fix this later, sorry about that for the mo. 

filesystems that have been done are:

ffs + softdep (extattr not looked at, sorry)
nullfs 
kernfs 
fdescfs 
portalfs 
cd9660 
fifofs
