Treat SIGINT correctly in GUI sessions on MS-Windows
* src/w32proc.c (sys_signal): Don't reject SIGINT, as it is
supported by MS runtime.
* src/term.c (DEV_TTY): Move from here ...
* src/conf_post.h (DEV_TTY): ... to here. Separate definitions
for WINDOWSNT and for the rest.
* src/keyboard.c (handle_interrupt_signal): Use DEV_TTY instead of
a literal "/dev/tty".
* etc/NEWS: Mention the behavior change.
