[PATCH 0/5] Fix for an assertion when unwinding with inline frames

[Andrew Burgess]

This series fixes an assertion I ran into when unwinding a stack
containing inline frames (patch #4).

I also fix an assertion from the 'set debug frame 1' code when I ran
into when trying to debug the first assertion (patch #5).

I also fix an assertion in the Python unwinder API that I ran into
while trying to write a test for the first assertion, this ended up
with me extending the functionality of the unwinder API a little,
which is nice (patch #1).

Then I needed to add some additional methods to the Python
Frame/PendingFrame API so I could write the test for the first
assertion (patch #3).

Finally, there was a small drive by clean up which related to the new
Frame/PendingFrame API extension (patch #2).

Thoughts welcome,

thanks,
Andrew
