Global rpmlogCode (void): Perl-RPM needs, what's really needed is predictable, non-i18n encumbered, error text that can be retrieved through rpmlogMessage() and parsed IMHO.
Global rpmShowProgress (const void *arg, const rpmCallbackType what, const rpm_loff_t amount, const rpm_loff_t total, fnpyKey key, void *data): Transaction callback arguments need to change, so don't rely on this routine in the rpmcli API.
