In attached patch, I have moved pgpipe, piperead functions to src/port/pipe.c

There are some more common function what Jeff and Amit also mentioned to move to common place,
Currently I am not sure where we can move other functions to.
Can we move other parallel functions to src/port, may be one new file parallel.c under src/port ?
