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.
* send end_of_data event for all kind of streams
* send process_finished event containing exit code of child process for executed programs
* move raw-tests to separate directory
* expose name of input stream to readers
* better handling of some error cases in raw reader
* new force_kill option for raw reader which SIGKILLs progesses on exit
The ordering of events how they arrive in the main loop is a bit peculiar at the moment.
The process_finished event arrives in scriptland before all of the other events, even though
it should be sent last. I have not yet fully figured that out.
