The old trGettext() was not thread-safe and the returned C-strings could be freed in the case of empty translations strings. Therefore: 1) Introduce a mutex protecting access to the cache. 2) Never change existing entries, even if the translation string is empty. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
