Subject: Factor out setup_up / destroy_ui functions.

This pulls out and renames setup_ui/destroy_ui so we have something that
can be replaced as-needed, moving the the console setup code for Windows
to app_win.c in -portable, instead of needing a local patch to enable binary
console mode

ui_read/write are also simplified.
