libsysprof: add API to categorize callgraph

Browse Source 
This just gets the plumbing in place with some basic categorization for
callgraph information. The real work of categorizing by nick/symbol still
needs to be done (some can be copied from SysprofCategoryIcon).

This also adds a property and getter for SysprofCallgraphFrame which will
expose the node's category to the UI code.
