Blindly chose a cap of 10000 iterations for every loop, except for the two in script_ops.cpp and scriptnum_ops.cpp which appeared to (sometimes) be deserializing individual bytes; capped those to one million to ensure that sometimes we try working with massive scripts. There was also one fuzzer-controlled loop in timedata.cpp which was already capped, so I left that alone. git grep 'while (fuzz' should now run clean except for timedata.cpp
