Konstantin Belousov 30d49d536b Try to decrease the number of bugs in unionfs after the VV_TEXT flag removal. 
- Provide unionfs_add_writecount() which passes the writecount to the
  lower or upper vnode as appropriate.
- In unionfs VOP_RECLAIM() implementation, annulate unionfs
  writecounts from upper or lower vnode.  It is not clear that it is
  always correct to remove the all references from either lower or
  upper vnode, but we currently do not track which vnode get how many
  refs anyway.
