NOTE: This issue is part of the "SymfonyCon 2014 Madrid Hackday" effort to add logs for every 2.7 deprecated feature. This is needed before removing those features in 3.0 version. Please, add you name in a comment of this issue if you are going to work on this.
The methods ChoiceListInterface::getIndicesForChoices() and
ChoiceListInterface::getIndicesForValues() were removed. No direct
replacement exists, although in most cases
ChoiceListInterface::getChoicesForValues() and
ChoiceListInterface::getValuesForChoices() should be sufficient.
