Move some shared code to a localetools module

The time-zone script was importing two functions from the locale data
generation script. Move them to a separate module, to which I'll
shortly add some more shared utilities. Cleaned up some imports in the
process.

Combined qlocalexml2cpp's and xpathlit's error classes into a new
Error class in the new module and made it a bit more like a proper
python error class.
