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

Sort include lines (ignoring hacky cli test utils).
Put ccan first, openssl next, then standard headers, then locals.

Move bitcoin stuff into bitcoin subdir.
It's not very interesting if you're looking for LN code.

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.

Use raw 64-byte signatures in protocol.
DER encoding introduces problems for non-canonical encodings; we should
do that only at the lightning<->bitcoin interface.
