Kevin Krakauer 0a8a75f3da Job control: controlling TTYs and foreground process groups. ... Adresses a deadlock with the rolled back change: b6a5b950d2 Creating a session from an orphaned process group was causing a lock to be acquired twice by a single goroutine. This behavior is addressed, and a test (OrphanRegression) has been added to pty.cc. Implemented the following ioctls: - TIOCSCTTY - set controlling TTY - TIOCNOTTY - remove controlling tty, maybe signal some other processes - TIOCGPGRP - get foreground process group. Also enables tcgetpgrp(). - TIOCSPGRP - set foreground process group. Also enabled tcsetpgrp(). Next steps are to actually turn terminal-generated control characters (e.g. C^c) into signals to the proper process groups, and to send SIGTTOU and SIGTTIN when appropriate.
