move plugin text codecs to QtCore
Having plugin text codecs adds considerable complexity to configuring Qt. The plugin interface is designed for optional features, but text codecs tend to be used for essential functions. A dramatic example is loading a codec plugin from a file whose path needs to be converted by the codec. Codec plugins can also be a nuisance to builders of applications linking to static Qt. This is because the application might need to explicilty import the static codec plugins which are actually dependencies of QtCore. For these reasons, it has been decided not to have text codec plugins any longer.
