Subject: SUNRPC: two small improvements to rpcauth shrinker.

1/ If we find an entry that is too young to be pruned,
  return SHRINK_STOP to ensure we don't get called again.
  This is more correct, and avoids wasting a little CPU time.
  Prior to 3.12, it can prevent drop_slab() from spinning indefinitely.

2/ Return a precise number from rpcauth_cache_shrink_count(), rather than
  rounding down to a multiple of 100 (of whatever sysctl_vfs_cache_pressure is).
  This ensures that when we "echo 3 > /proc/sys/vm/drop_caches", this cache is
  still purged, even if it has fewer than 100 entires.

Neither of these are really important, they just make behaviour
more predicatable, which can be helpful when debugging related issues.

Subject: sched/headers: Prepare to remove <linux/cred.h> inclusion from
 <linux/sched.h>

Add #include <linux/cred.h> dependencies to all .c files rely on sched.h
doing that for them.

Note that even if the count where we need to add extra headers seems high,
it's still a net win, because <linux/sched.h> is included in over
2,200 files ...
