Rusty Russell 1d82bf51fc signature: fix invalid S check.
The even-S check was based on https://github.com/sipa/bitcoin/commit/a81cd9680
which was replaced by a low-S check in commit e0e14e43d9586409e42919f6cb955540134cda2a

Abstract out and fix the check.

Rusty Russell d20ddb5a90 Use libsecp256k1 instead of openssl for crypto.
We still use openssl for bignums (base58) and for ripemd.

Rusty Russell 602117e8bb 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.

Rusty Russell 143e7e032c Optimize revocable output a little.
Both paths do CHECKSIG, do that outside.

Rusty Russell 9f12b72476 Don't include mutual redemption in recovable commit tx output.
It's not clear it's needed, and without it there's a good reason to
delay dumping to the blockchain if a node becomes unreachable (since
you'll get your money faster if it comes back online).

Rusty Russell ef9463f6b1 Sort include lines (ignoring hacky cli test utils).
Put ccan first, openssl next, then standard headers, then locals.

Rusty Russell 612d713470 Move bitcoin stuff into bitcoin subdir.
It's not very interesting if you're looking for LN code.
