Introduce owning_ptr<T>; use it for JPEG2KEncode and JPEG2KDecode.

owning_ptr<T> adapts std::unique_ptr<T> to be a better drop-in replacement for
a legacy class that formerly stored plain T* data members, and explicitly
destroyed them using domain-specific destructor functions.

Directly substituting std::unique_ptr into JPEG2KEncode and JPEG2KDecode was
cumbersome because every such pointer declaration required a redundant
template parameter describing the deleter function passed into its
constructor. Moreover, it required lots of little syntax tweaks: changing
every assignment to a reset() call, changing every reference to a get() call.

Using owning_ptr<T> allows us to leave the code more or less as it was before,
save that assignment and destruction automatically handle the previous
referenced T instance.
