  Modified files:
    sys/conf             files 
    sys/geom             geom.h geom_dev.c geom_int.h geom_io.c 
                         geom_kern.c geom_subr.c 
    sys/geom/bde         g_bde_lock.c g_bde_work.c 
  Added files:
    sys/geom             geom_stats.c geom_stats.h 
  Log:
  Move the g_stat struct to its own .h file, we will export it to other code.
  
  Insted of embedding a struct g_stat in consumers and providers, merely
  include a pointer.
  
  Remove a couple of <sys/time.h> includes now unneeded.
  
  Add a special allocator for struct g_stat.  This allocator will allocate
  entire pages and hand out g_stat functions from there.  The "id" field
  indicates free/used status.
  
  Add "/dev/geom.stats" device driver whic exports the pages from the
  allocator to userland with mmap(2) in read-only mode.
  
  This mmap(2) interface should be considered a non-public interface and
  the functions in libgeom (not yet committed) should be used to access
  the statistics data.
