thorpej 9ec517a68e Changes necessary to implement pre-zero'ing of pages in the idle loop: 
- Make page free lists have two actual queues: known-zero pages and
  pages with unknown contents.
- Implement uvm_pageidlezero().  This function attempts to zero up to
  the target number of pages until the target has been reached (currently
  target is `all free pages') or until whichqs becomes non-zero (indicating
  that a process is ready to run).
- Define a new hook for the pmap module for pre-zero'ing pages.  This is
  used to zero the pages using uncached access.  This allows us to zero
  as many pages as we want without polluting the cache.

In order to use this feature, each platform must add the appropropriate
glue in their idle loop.
