David Xu cf7d9a8ca8 Create a global thread hash table to speed up thread lookup, use 
rwlock to protect the table. In old code, thread lookup is done with
process lock held, to find a thread, kernel has to iterate through
process and thread list, this is quite inefficient.
With this change, test shows in extreme case performance is
dramatically improved.
