Alan Cox 65bae14d77 - Enable recursive acquisition of the mutex synchronizing access to the
free pages queue.  This is presently needed by contigmalloc1().
 - Move a sanity check against attempted double allocation of two pages
   to the same vm object offset from vm_page_alloc() to vm_page_insert().
   This provides better protection because double allocation could occur
   through a direct call to vm_page_insert(), such as that by
   vm_page_rename().
 - Modify contigmalloc1() to hold the mutex synchronizing access to the
   free pages queue while it scans vm_page_array in search of free pages.
 - Correct a potential leak of pages by contigmalloc1() that I introduced
   in revision 1.20: We must convert all cache queue pages to free pages
   before we begin removing free pages from the free queue.  Otherwise,
   if we have to restart the scan because we are unable to acquire the
   vm object lock that is necessary to convert a cache queue page to a
   free page, we leak those free pages already removed from the free queue.
