It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_blkid_to_hex() so it's reversed as people expect.

We were using the bitcoin genesis blockhash for all networks, which is
not correct, and would result in the open being aborted when talking
to other implementations.

Like txids, we need to reverse them. We didn't, but then we only used them
to pass to/from bitcoind. We're about to get them from the block header,
so we need to fix that.
