Update C++ and Python interfaces.

* include/mailutils/prog.h: Add extern "C".
* include/mailutils/wordsplit.h: Likewise.
* libmu_cpp/address.cc (Address::to_string): Use mu_address_sget_printable.
* libmu_cpp/filter.cc (FilterIconvStream): Use mu_filter_create_args.
* python/mailutils/folder.py (get_stream, set_stream): Remove.
