Major tidy up and rework of options tree and set-option/show-options
commands this pushes more of the code into options.c and ties it more closely to the options table rather than having an unnecessary split. Also add support for array options (will be used later). Only (intentional) user visible change is that show-options output is now passed through vis(3) with VIS_DQ so quotes are escaped.
