Matthew Dillon b5810bab2d After extensive testing it has been determined that adding complexity 
to avoid removing higher level directory vnodes from the namecache has
no perceivable effect and will be removed.  This is especially true
when vmiodirenable is turned on, which it is by default now.  ( vmiodirenable
makes a huge difference in directory caching ).  The vfs.vmiodirenable and
vfs.nameileafonly sysctls have been left in to allow further testing, but
I expect to rip out vfs.nameileafonly soon too.

I have also determined through testing that the real problem with numvnodes
getting too large is due to the VM Page cache preventing the vnode from
being reclaimed.  The directory stuff made only a tiny dent relative
to Poul's original code, enough so that some tests succeeded.  But tests
with several million small files show that the bigger problem is the VM Page
cache.  This will have to be addressed by a future commit.
