The 095-recursive-define test case was triggering infinite recursion
with the following test case:
#define A(a, b) B(a, b)
#define C A(0, C)
C
Here's what was happening:
1. "C" was pushed onto the active list to expand the C node
2. While expanding the "0" argument, the active list would be
emptied by the code at the end of _glcpp_parser_expand_token_list
3. When expanding the "C" argument, the active list was now empty,
so lather, rinse, repeat.
We fix this by adjusting the final popping at the end of
_glcpp_parser_expand_token_list to never pop more nodes then this
particular invocation had pushed itself. This is as simple as saving
the original state of the active list, and then interrupting the
popping when we reach this same state.
With this fix, all of the glcpp-test tests now pass.
