    General cleanup related to the new pager.  We no longer have to worry     about conversions of objects to OBJT_SWAP, it is done automatically     now.

    Replaced manually inserted code with inline calls for busy waiting on
    pages, which also incidently fixes a potential PG_BUSY race due to
    the code not running at splvm().

    vm_objects no longer have a paging_offset field ( see vm/vm_object.c )
