gossipd: erase old entries from the store, don't just append.
We use the high bit of the length field: this way we can still check that the checksums are valid on deleted fields. Once this is done, serially reading the gossip_store file will result in a complete, ordered, minimal gossip broadcast. Also, the horrible corner case where we might try to delete things from the store during load time is completely gone: we only load non-deleted things.
