* syscalls.cc (login): Use pututiline().
(setutent): Open utmp as read/write.
(endutent): Check if utmp file is open.
(utmpname): call endutent() to close current utmp file.
(getutid): Enable all cases, use strncmp() to compare ut_id fields.
(pututline): New.
* tty.cc (create_tty_master): Set ut_pid to current pid.
* fhandler.h (fhandler_serial::vmin_): Declare as size_t.
* fhandler_serial.cc (fhandler_serial::raw_read): Use correct type for
minchars.
(fhandler_serial::ioctl): Set errno if the ClearCommError fails.
(fhandler_serial::tcsetattr): Use correct value for vmin_.
(fhandler_serial::tcgetattr): Ditto.
