  1. src: remap invalid file descriptors using dup2 

    When checking for the validity of the stdio file descriptors
(nodejs#875), ones which don't exist are intended to be remapped to
/dev/null (and, if that doesn't work, we abort).

This however doesn't work on all platforms and in all cases, and is not
anymore required by POSIX; instead, use the `dup2` syscall as a more
robust solution (conforms to POSIX.1).

Fixes: nodejs/help#2411
Refs: nodejs#875
