daishengdong d0b8d0675e add ring queue/message queue/mail queue, binary heap/priority queue/priority message queue/priority mail queue
1. remove the old msg queue and queue:
i. msg queue is not a common and reusable/flexible component(need user to config the msg pool size and this componet can only be used by tos_queue)
ii. tos_queue can only deliver the pointer message(cannot do a memory buffer deliver)

2. add ring queue(tos_ring_q) componet
rinq queue can be reused by tos_chr_fifi/tos_msg_q/tos_mail_q as the foundational data container

3. add message queue(tos_msg_q)
a little like the old queue mechanism, supply the capability to deliver a pointer message

4. add mail queue(tos_mail_q)
supply the capability to deliver a memory buffer

5. add binary heap(tos_bin_heap)
the basement componet to implement priority queue

6. add priority queue(tos_prio_q)
can be reused by the priority message/mail queue  as the foundational data container.

7. add priority message queue(tos_prio_msg_q)
a message(pointer) deliver mechanism, supply the capability of delivering the message with priority(message with higher priority comes faster to the pender than with lower)

8. add priority mail queue(tos_prio_mail_q)
a mail(memory buffer) deliver mechanism, supply the capability of delivering the mail with priority(mail with higher priority comes faster to the pender than with lower)
