* fhandler.h (fhandler_pty_master::tcgetpgrp): Declare.
* fhandler_termios.cc (fhandler_termios::tcgetpgrp): Only return
valid pgid if tty is controlling tty. Set errno to ENOTTY and
return -1 otherwise.
(fhandler_pty_master::tcgetpgrp): New function. Return 0 for
master side of pty if it's not the controlling tty of the process.
