The following is a patch for PR gdb/mi 680.  To summarize, the patch changes
all usages of ui_out_tuple_begin/ui_out_tuple_end and ui_out_list_begin/ui_out_list_end
in the mi code to use the make_cleanup_ui_out_xxxx_begin_end/do_cleanups alternative.  This patch
was generated from code that contains other patches I have made that have not yet been 
approved so I have diff'd so only the changes pertaining to this PR are shown.
