Subject: [PATCH 48/66] kconfig: gconf: do not reconstruct tree store when a symbol is changed

There is no need to reconstruct the entire tree store when a symbol's
value changes. Simply call gtk_tree_store_set() to update the row data.

Introduce update_trees() to factor out the common update logic.
