Use libsecp256k1 instead of openssl for crypto.
We still use openssl for bignums (base58) and for ripemd.

Add valgrind memcheck helpers.
Otherwise valgrind tells you when you test a hash; you want to
know if you hash uninitialized memory long before that.

protocol: fix horribly thinko, keep own secrets.
I had each side using the other side's hash secret. That's a very
dumb idea, since it means you can steal from a unilateral close!
A's secret applies to A's commit transaction: it needs the
secret and B's final signature to steal funds, and that should
never happen (since A doesn't have the B's final signature, and
once A has given B the secret, they never broadcast the commit tx).
This makes the update a 4 step dance, since you need the new
revocation hash to make the other side's TX to sign.
