[RFA 2/5] Introduce ui_file_up and use it to remove cleanups

This introduces a new ui_file_up typedef, which is a specialization of
unique_ptr that calls ui_file_delete. This patch also changes
mem_fileopen to return a ui_file_up, and fixes the users. It also
updates a few other spots in the Python code to use this rather than
cleanups.
If at some point ui_file_delete is removed in favor of a destructor, I
think the typedef could be changed and the default deletion policy
used instead.
