Petr Viktorin a93fc02af6 Raise an error when updating CIDict with duplicate keys 
Updating a CIDict with data like {'A': 1, 'a': 2} would lead to data
loss since only one of the items would get to the CIDict.
This can result in non-obvious bugs similar to this one in python-ldap:
https://bugzilla.redhat.com/show_bug.cgi?id=1007820

Raise an error in this case; any resolution must be done by the caller.
