eitd: Reduce sectionsd memory requirements:

* Various EPG related strings (language- and country keys, audio descriptions) come with a pretty low variance. Cache them, and use an index instead of allocating redundant strings for each and every SIevent. * Storing content classifications in native format instead of std::string removes quite some memory overhead, too. This saves about 250 bytes of RAM for every event cached, resulting in a considerably reduced sectionsd memory footprint. Conflicts: src/eitd/xmlutil.cpp
