Avoid unnecessary detaching of containers

Browse Source 
If only a constant iterator is needed, make the container const if
possible, otherwise use cbegin() and cend() to get a constant iterator
without detaching the container.

These fixes are needed so that `auto` can deduce the correct
iterator type.
