Axel Dörfler d5ad762913 Fixed several problems of the prefetching code:

* Did claim to have reserved pages when calling vm_page_allocate_page(), but
  didn't have any (copy&paste bug). We cannot use it without reserved pages,
  as we need to call vm_page_allocate_page() with a cache locked.
* No longer use low_resource_state() to determine whether to precache or not,
  but use the new vm_page_num_used_pages() instead.
* Also don't (try to) precache when the cache already has more than 2/3 of its
  pages to safe some unnecessary work.
* The size to precache was limited to the file size incorrectly.
* When precaching failed, the cache reference was not released.
* The precaching started one page too late, causing bug #3835.
* Reenabled precaching.
