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.
