ui/ncurses/nc-widgets: Add initial textbox validation functions

We'd like to do some validation of the system configuration parameters,
so add a few validation types to the widget code. We currently need
integer, ipv4 address and multiple ipv4 address types. These are
implemented as small wrappers around the ncurses form validator code.
