a0bcf85bd4 Active file descriptor watches and active timers are now automatically transferred to the component declaring a custom event loop.
[INTERPRETER]
* BUG: Active file descriptor watches and active timers are now automatically transferred to the component declaring a custom event loop. Consequently, a process started before the declaration of the event loop will have its termination signal correctly catched.
* NEW: Use waitpid() instead of wait4().

f45192abb2 Fix pseudo-terminal management again. Now processes run through a terminal set the ECHO flag, and do not clear the OCRNL flag.
[INTERPRETER]
* NEW: Initialize pseudo-terminals with ECHO and don't clear OCRNL flag. This is not compatible with previous versions, as now, by default, printing a NL will become CR+NL through the pseudo-terminal.
  But I didn't succeed in modifying the pseudo-terminal reliably once the child has started. It sometimes fails silently.

[DEVELOPMENT ENVIRONMENT]
* BUG: Terminal: Replace "\n" by "\r\n" when sending text to the output terminal.

[INTERPRETER]
* NEW: When a process is run with a pseudo-terminal, don't set the ECHO flag, and clear the ONLCR flag.
  That way, the data printed on the standard output is the same as when the process is not run in a pseudo-terminal.

[GB.FORM.TERMINAL]

* BUG: Tasks do not inherit signal handler pipe anymore, they recreate it instead. Otherwise you have interferences with the parent process of the task, and some signals are lost.
* BUG: Buffered streams now take the internal stream flag "available_now" into account. No idea why that was disabled.
* BUG: Standard streams now set the internal stream flag "available_now" if they are not connected to a terminal. Which may not be necessarily accurate, so it is a temporary change.
