libsysprof-analyze: implement augmented callgraph

Browse Source 
This creates a SysprofCallgraph object which is a GListModel of
SysprofCallgraphFrame. The SysprofCallgraphFrame is also a GListModel of
SysprofCallgraphFrame so that we can map this all into a GtkListView in
the future for tree-like visibility.

The augmentation allows for the same callgraph code to be used for multiple
scenarios such as CPU sampling as well as memory allocation tracking.

If your augmentation size is <=sizeof(void*) then you do not occur an extra
allocation and you can use the inline augmentation space.

The test-callgraph clearly shows that we still need to do the shuffling
of -- Kernel -- and -- User -- like the old callgraph code did. But that
will come soon enough.
