Merge remote-tracking branch 'origin/topic/bernhard/input-update'

Closes #1021.

* origin/topic/bernhard/input-update:
  this event handler fails the unused-event-handlers test because it is a bit of a special case.
  ...and fix the event ordering issue. Dispatch != QueueEvent
  add Terminate to input framework to prevent potential shutdown race-conditions.
  fix warning.
  fix stderr test. ls behaves differently on errors on linux...
  small fixes.
  linux does not have strnstr
  and close only fds that are currently open (the logging framework really did not like that :) )
  A bunch of more changes for the raw reader
  make reading from stdout and stderr simultaneously work.
  allow sending data to stdin of child process
  Streaming reads from external commands work without blocking anything.
  replace popen with fork and exec.
  change raw reader to use basic c io instead of fdstream encapsulation class.
