Library function identifier based on correlation

Using library function identification ala fenris was very useful, but a bunch of functions remained unidentified, although we thought that some of them were also libc functions. After some investigation we thought that this task could still be automatized: if we get first 100 bytes of a function and correlate them with the first 100 of every library function, the maximum correlation could indicate a real match for this type of functions.

A real application should compute a mathematical correlation, but we were in a hurry: we developed some scripts to just compare these 100 bytes, one by one. These are the new utilities:
