    kernel - VM PAGER part 2/2 - Expand vinitvmio() and vnode_pager_alloc()
    
    * vinitvmio() is responsible for assigning the initial VM object size based
      on the file size.  Adjust vinitvmio() to conform to the new nvextendbuf()
      and nvtruncbuf() API.
    
    * vinitvmio() has been given two additional parameters, blksize and boff,
      to allow it to determine how much larger the VM object must be relative
      to the byte-granular file size passed to it.
    
    * Remove vm_page_alloc() and remove the pgo_alloc vector from struct
      pagerops.  Convert all the VM pager allocation procedures into global
      procedures which are called directly.  Trying to feed everything through
      a single function was a joke when all the callers knew precisely what
      kind of VM object they were creating anyway.
    
      Add the extra arguments to vnode_pager_alloc() which vinitvmio() needs
      to pass in.
