* 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.
This lead to hanging bro's because pclose apparently can wait for eternity
if things go wrong. And there probably are a couple of other problems with this approach.
support reading from commands by adppending | to the filename.
support streaming reads from command.
Fix something to make rearead work better. (magically happened)
