fix libraries take care the case of rte_lcore_id() >= RTE_MAX_LCORE.
Thanks a million for the comments from Konstantin, Bruce, Mirek and Stephen in
RFC review.

It returns the socket_id if all cpus in the cpuset belongs
to the same NUMA node, otherwise it will return SOCKET_ID_ANY.

1. add two TLS *_socket_id* and *_cpuset*
2. add two external API rte_thread_set/get_affinity
3. add one internal API eal_thread_dump_affinity

The API works for both EAL thread and none EAL thread.
When calling rte_thread_set_affinity, the *_socket_id* and
*_cpuset* of calling thread will be updated if the thread
successful set the cpu affinity.

The rte_gettid() wraps the linux and freebsd syscall gettid().
It provides a persistent unique thread id for the calling thread.
It will save the unique id in TLS on the first time.

For those non-EAL thread, *_lcore_id* is invalid and probably larger than
RTE_MAX_LCORE.
The patch adds the check and allows only EAL thread using EAL per thread log
level and log type.
Others shares the global log level.

In non-EAL thread, lcore_id alrways be LCORE_ID_ANY.
It cann't be used as unique id for recursive spinlock.
Then use rte_gettid() to replace it.

For those none EAL thread, *_lcore_id* shall always be LCORE_ID_ANY.
The libraries using *_lcore_id* as index need to take care.
*_socket_id* always be SOCKET_ID_ANY unitl the thread changes the affinity
by rte_thread_set_affinity()

Add a sched_yield() syscall if the thread spins for too long, waiting other
thread to finish its operations on the ring.
That gives pre-empted thread a chance to proceed and finish with ring
enqnue/dequeue operation.
The purpose is to reduce contention on the ring.

It will get bad performance and has critical risk if scheduling policy is RT.
