[PATCH 0/5] Improve Python Inferior reference handling + fix a bug

[Simon Marchi]

As I was investigating a crash related to Python Inferior objects, I saw some
opportunities to make the code a bit nicer/robust.  This series is the result.

Simon Marchi (5):
  Introduce specialized versions of gdbpy_ref
  Add Python Inferior object debug traces
  Make Python inferior-related internal functions return
    inferior_object*
  Make Python inferior-related internal functions return a gdbpy_inf_ref
  Add missing incref when creating Inferior Python object
