[performance] improve performance in Harmony network and IO classes
-------------------------------------------------------------------

                 Key: HARMONY-6456
                 URL: https://issues.apache.org/jira/browse/HARMONY-6456
             Project: Harmony
          Issue Type: Task
         Environment: all
            Reporter: Jimmy, Jing Lv


The current performance of networking/io is a bit slow in Harmony implementation. Much work
to be done to improve as:
1. use high performance native API like readv/writev instead to fill the arrays of data
2. simplify the native call stack to save time;
3. reduce unnecessary array copy in the data read/write 
4. remove unnecessary synchronizations
5. remove redundant varieties
etc.
