This now works because we no longer call out to masterd or bitcoind to verify
the channels. It's also rather quick and silent so we can just process all
stored messages until we're done.

This stores and reads the channel_announcements in the wrapping message which
allows us to store associated data with the raw channel_announcements.
The gossip_store applies channel_announcements directly but it also returns it,
and it gets discarded as a duplicate. In the next commit we'll have gossip_store
apply all changes, bypassing verification, so the duplication is only temporary.

Since we now store additional data along with the original messages they exceed
the length of the peer wire protocol messages.

If we have a non-empty file and the version doesn't match, then we truncate and
write our own version. If the file is empty we write our version and the
truncate becomes a no-op

As proposed by @rustyrussell this makes it a bit easier to truncate and sync on
read errors.
