terminfo has replaced termcap

NetBSD-6 will now sport the terminfo interface which removes a lot of the problems with the old termcap which is deprecated by The Open Group. Upgrading existing systems should be quite painless as the old termcap interface is still provided, but there are some caveats.

• $TERMCAP is no longer supported, tset -s no longer exports it. So if you maintain your own terminal definition, you'll need to use tic(1) on a small terminfo database in $HOME.
• NetBSD extensions to termcap are no longer supported. Only 3rd party applications that used these would be affected.

This should allow pkgsrc not to need ncurses for a fair few console applications, like say tmux.
