[PATCH v2 00/31] More cleanup elimination & unlimited args to user-defined funcs


This is v2 of the series first sent here:
  https://sourceware.org/ml/gdb-patches/2016-10/msg00223.html

v1's patch #1 is in master now.

v1's patch #2 never made it to the list in v1 for some reason.  This
time, I've split that patch in many smaller pieces.

v1's patch #3 is the struct parse_expression one here.

I've added a few new patches as well:

E.g., one uses unique_ptr to manage agent_expr owning pointers,
similar to the struct expression one.  (My goal here to show the
direction I think we should head.  Help would be much appreciated in
applying the pattern to other random cases.)

The collection_list patch here is much more complete than what was in
v1.

And, so you don't all think C++fication is just pointless churn, the
last patch in the series is new too, and actually implements something
IMO useful.  :-)
