fuzz: extract some common utilities and use modern C++ idioms
Alex Gaynor suggested we should probably copy the left and right sides
of diffs to new blocks so we can detect over-reads in the diffing
code, and I agree. Once I got into that, I realized we should do
things with C++17 idioms rather than keep using malloc() and
free(). This change is the result. I tried to split it more than this
and failed.
Everything still compiles and works in the oss-fuzz container, so I
think we can count on C++17 being available!
