I'd begin with GNU ID-Utils.  They generate a database of all the
symbols in a source tree, and let you run queries on that adatabase.
There's a nice grep-like Emacs inteface to the most frequently-used
query (find all the lines where a certain symbol or a symbol-name
pattern is mentioned), but even if you use the less frequent queries
outside Emacs, you could then add some simple scripts on top of that.

Look at the GNU FTP site for the latest version of ID-Utils.  I find
it a must when browsing a large source tree.
