* dtable.cc (dtable::stdio_init): Always initialize console when we have one.

* fhandler_termios.cc (fhandler_termios::tcsetpgrp): Use a better method to
print tty name for debugging.
(fhandler_termios::bg_check): Ditto.
* pinfo.cc (_pinfo::set_ctty): Remove leftover debugging stuff.  Simplify
behavior when setting tty's sid and pgid to avoid overwriting previously set
values.
* spawn.cc (ch_spawn): Cosmetic change.
