i.e., css::uno::Any function template specializations Any::has<Any>() const Any::get(Any const &) const operator >>=(Any const &, Any &) operator <<=(Any &, Any const &) that don't make much sense (the first is always true, the rest can be replaced with operator =, which additionally supports move semantics). For 3rd-party compatibility, do this only for LIBO_INTERNAL_ONLY, however. However, some generic template code did benefit from operator >>= working also for Any, so make up for that with a new (LIBO_INTERNAL_ONLY, given that operator >>= still covers if fine for !LIBO_INTERNAL_ONLY) fromAny, complementing the existing toAny.
