Comment:
I have a branch called `ftrapv` that makes everything besides donna32
compile with trapv, and makes donna32 compile with wrapv.
One more thing before we can merge, though: I want to know the effect of
ftrapv on whether our generated signed-integer-using crypto is still
constant-time. In particular this includes: ed25519 signatures,
curve25519, keccak, di_ops.c, and I hope not too much else.
