sched/prio: Add 3 macros of MAX_NICE, MIN_NICE and NICE_WIDTH in prio.h
Currently there is lots of hard coding to 19 and -20, to represent
maximum and minimum of nice values.
This patch add three macros in prio.h for maximum, minimum and width
of nice value, and uses it to remove hardcoded values in prio.h.

sched/prio: Use DEFAULT_PRIO to define NICE_TO_PRIO() and PRIO_TO_NICE()
There is already a macro named DEFAULT_PRIO in prio.h, we can use it
to define NICE_TO_PRIO and PRIO_TO_NICE rather than use hard coding
of (MAX_RT_PRIO + 20).

sched: Implement task_nice() as static inline function
As patch "sched: Move the priority specific bits into a new header file" exposes
the priority related macros in linux/sched/prio.h, we don't have to implement
task_nice() in kernel/sched/core.c any more.
This patch implements it in linux/sched/sched.h as static inline function,
saving the kernel stack and enhancing performance a bit.

sched: Expose some macros related to priority
Some macros in kernel/sched/sched.h about priority are
private to kernel/sched. But they are useful to other
parts of the core kernel.
This patch moves these macros from kernel/sched/sched.h to
include/linux/sched/prio.h so that they are available to
other subsystems.

sched: Move the priority specific bits into a new header file
Some bits about priority are defined in linux/sched/rt.h, but
some of them are not only for rt scheduler, such as MAX_PRIO.
This patch move them all into a new header file, linux/sched/prio.h.
