Add a new callback to handle softmmu paging. Return the page
details directly, instead of passing them indirectly to
tlb_set_page. Handle alignment simultaneously with paging so
that faults are handled with target-specific priority.
Route all calls of the two hooks through a tlb_fill_align
function local to cputlb.c.
As yet no targets implement the new hook.
As yet cputlb.c does not use the new alignment check.
