The locking and reference counting in this patch is highly dubious; also, 
vn_fullpath() should really not be used this way, as it fails whenever vnodes 
fall out of the name cache or a file system doesn't use the namecache (i.e., 
it is purely advisory).  If we're going to do openat() in the Linux emulation 
layer, let's instead implement it properly in the FreeBSD system call code as 
a first class service and then wrap it the way we wrap other system calls. 
Please do not MFC this patch as-is.
