Add a terminal-overrides session option allowing individual terminfo(5) entries to be overridden. The 88col/256col checks are now moved into the default setting and out of the code. Also remove a couple of old workarounds for xterm and rxvt which are no longer necessary (tmux can emulate them if missing).
