A series patches about sched priority.

Hi all,
This patchset is all about priority.

1. Add two inline functions in prio.h named nice_to_rlimit and rlimit_to_nice. They are converting the value between nice value [-20, 19] and rlimit style value [1, 40].
2. Add a macro in ioprio.h named NICE_TO_IOPRIO.
It convert nice value [-20, 19] to io priority [0, 7].
3. Others are all about replace hardcoding value about nice to MIN_NICE or MAX_NICE.

Changelog:
-v2:
*Splite [2/16] into two patches, one is about the whitespace changes, and
the other is about nice_to_rlimit().
-v1:
*Implement nice_to_rlimit and rlimit_to_nice with inline functions
rather than macro.
*Add a patch[16/16] to replace opened code implement with nice_to_rlimit().
