[PATCH 0/2] [gdb/python] Remove Py_RETURN_{NONE,TRUE,FALSE}

[Tom de Vries <tdevries@suse.de>]

I came across this code:
...
   if (c)
     return v;
   else
     Py_RETURN_NONE;
...
and realized I couldn't easily rewrite it into "return c ? v : ...".

Probably something like this would work:
...
  return c ? v : ([] { Py_RETURN_NONE; } ());
...
but it made me wonder if we can rid of Py_RETURN_NONE.

The only point of it seems to be to increase the reference count on the
Py_None object for older python versions.

ISTM unnecessary to increase the reference count for each Py_RETURN_NONE use.

Instead, increase the reference count of Py_None once, and use a simple
"return Py_None" instead of Py_RETURN_NONE everywhere.
