increasing efficiency  when doing CPU consuming routine

This branch focus on increasing efficiency  when doing CPU consuming
routine

Compared with creating new processes, a more excellent solution are:
1 Without creating a process, Create a new thread in the same process.
Post a task to the working thread.
2 CPU consuming specific logical operations supports C + + and Js
implementation.
3 easy use and efficient.

In order to achieve these three goals, we adds 'pt_c' built-in C + +
modules.
