Update baseline of stderr test to what it should be. There still is
a message ordering issue there (which is the last issue in the new
Raw reader I know of).
One message that sidesteps a bit of the usual processing does
not always arrive at the correct time (meaning it pops up from the
event queue too early). Even though it sidesteps a bit of the usual
processing that should not happen in my opinion (which clearly
does not matter). And I have not yet fully grasped how this can happen.
* 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.
