Add a per-pane option set. Pane options inherit from window options (so

there should be no change to existing behaviour) and are set and shown
with set-option -p and show-options -p.

Change remain-on-exit and window-style/window-active-style to be pane
options (some others will be changed later).

This makes select-pane -P and -g unnecessary so no longer document them
(they still work) and no longer document set-window-option and
show-window-options in favour of set-option -w and show-options -w.
