It's too small to justify standalone existence.
We can accumulate i18n things we link to directly into
i18nutil and rework i18npool uno implementions in terms
of thin wrappers over i18nutil and prefer linking to
i18nutil internally and leave the uno forwarders for
use by external components and scripting
Berkeley DB is used for help index and extension database. (Possibly
only for a backward-compatible format of the latter, I am not sure.)
Neither use makes much sense on Android and iOS.
The existing help is for LO on desktop OSes anyway, help for LO-based
apps on iOS and Android will naturally be quite different.
On iOS there will definitely be no "extensions", and probably we don't
want to bother with such on Android either.
