Use g_timeout_add_once and g_idle_add_once
These functions, new in GLib 2.74, are nice helpers around g_timeout_add_full and g_idle_add_full, to avoid functions that only run once with the unconditional return G_SOURCE_REMOVE. There is quite a lot of those in the code-base, so update them to use the new helper functions.
