bitcoin/preimage: struct preimage. We had a hack for 'struct rval' in protobuf_convert.h; make an explicit header and put it in bitcoin/preimage.h. It's not really bitcoin-specific, but it's better than having bitcoin/script depend on an external header.

Update ccan/structeq. structeq() is too dangerous: if a structure has padding, it can fail silently. The new ccan/structeq instead provides a macro to define foo_eq(), which does the right thing in case of padding (which none of our structures currently have anyway). Upgrade ccan, and use it everywhere. Except run-peer-wire.c, which is only testing code and can use raw memcmp(): valgrind will tell us if padding exists. Interestingly, we still declared short_channel_id_eq, even though we didn't define it any more!
