Modified Files:
        src/sys/fs/tmpfs: tmpfs.h tmpfs_rename.c tmpfs_subr.c tmpfs_vfsops.c
            tmpfs_vnops.c

Log Message:
Change tmpfs to vcache.
- Use tmpfs node address as key.
- Remove tn_vlock, field tn_vnode now protected by vcache.
- Add a hold count to tmpfs node to prevent nodes from disappearing
  while tmpfs_fhtovp() trys to vcache_get() them.  Last holder
  destroys reclaimed nodes.
- Remove the now unneeded parent unlock/lock for lookup of '..'.
