kconfig: make kconfig MinGW friendly
Kconfig is powerfull tool. So powerfull that more and more software
projects are using it for configuration. So instead of fixing some of
them one by one, lets fix it in kernel and wait for sync.
This work was originaly done for PTXdist - GPL licensed build system for
userlands and cross-compilers, but it will not hurt kernel kconfig
either. PTXdist menuconfig now works on Windows linked with PDCurses and
compiled using MinGW - there is no termios and signals.
* Do not include <sys/wait.h> and <signal.h> (comes from times when
lxdialog was separate process)
* Do not mess with termios directly and let curses tell screen size.
Comment to commit c8dc68ad0fbd934e78e913b8a8d7b45945db4930 says
check for screen size could be removed later, but because it didn't
happen for more than year I left it here as well.
* Save cursor position added by Sam
