Bradley T. Hughes 992a37234c Don't crash by modifying read-only shared_null
Functions that modify the d-pointer must detach or otherwise take
measures to not modify the const, read-only shared_null.

The setSharable(bool) function takes care to detach when setting
sharable to false, but should avoid setting the sharable data member
unless d is not the shared null.

Similarly, QMap<Key, T>::setInsertInOrder() needs to detach if it is
shared with the shared_null (the logic has been updated to be the same
as setSharable()).
