v6:
    Add rte_ticketlock.h in lib/librte_eal/common/include/arch/arm/.
    Sort header inside ticketlock files by alphabetical order.

V3:
    1.Update ticketlock intrduction(suggested by Honnappa Nagarahalli).
    2.Change the implementation of rte_ticketlock_trylock to CAS(suggested by Honnappa Nagarahalli).

V2:
    1.Update commit message(suggested by Jerin Jacob).
    2.Add ticketlock test cases(suggested by Jerin Jacob).

V1:
    Implement ticket lock to improve lock fairness and prdictability.
