(IconvProcessor): Rework the implementation to fix two bugs:
- iconv_close was called even if the conversion descriptor was
invalid
- The compiler generated copy constructor did simply copy the pimpl_
pointer. Therefore pimpl_ was deleted twice for all IconvProcessor
instances created by eightbit_to_ucs4() and ucs4_to_eightbit().
This is solved by using a scoped_ptr for pimpl_.
