Clean up saving as PDF

This removes the global PDF_Password interface that had completely
bitrotted and moves it into the standard misc operation table with a
sensible defualt implementation.

This also cleans up and fixes the gtk frontend implementation of the
pdf password callback so it compiles.

Finally this moves the implementation to a sensible place alongside
the other exporters reducing target makefile complexity futher.
