sigchld_handler2.

[Alain St-Denis]

On 2.3.0p1, we have been experiencing the SSH2 stdout truncation problem
that was reported by a few users.

I built the 20010115 snapshot. It seems to correct the problem but
before I was able to test it, I had to change sigchld_handler2 so it
would not reset the signal handler before waitpid is called. On Irix, it
seems a SIGCHLD is delivered for ever...

I haven't tried the last snapshots so I don't know if this was fixed.
Here's a diff of what I did (basically just resetting it as it was for
2.3.0p1):

        errno = save_errno;
  }

0)
                                session_close_by_pid(pid, status);
+                       signal(SIGCHLD, sigchld_handler2);

                }
                channel_after_select(&readset, &writeset);
