    kernel - remove bounds on buffer cache nbuf count for 64-bit
    
    * Remove arbitrary 1GB buffer cache limitation
    
    * Adjusted numerous 'int' fields to 'long'.  Even though nbuf is not
      likely to exceed 2 billion buffers, byte calculations using the
      variable began overflowing so just convert that and various other
      variables to long.
    
    * Make sure we don't blow-out the temporary valloc() space in early boot
      due to nbufs being too large.
    
    * Unbound 'kern.nbuf' specifications in /boot/loader.conf as well.
