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.
