Now it just returns true if it queued something. This allows it
to queue multiple packets, and lets it share code paths with other code
in future patches.

As we add more features, the current code is insufficient.
1. Keep an array of single feature bits, for easy switching on and off.
2. Create feature_offered() which checks for both compulsory and optional
variants.
3. Invert requires_unsupported_features() and unsupported_features()
which tend to be double-negative, all_supported_features() and
features_supported().
4. Move single feature definition from wire/peer_wire.h to common/features.h.

We currently keep two copies; one in the broadcast structure to send
in order, and one in the routing information. Since we already keep
the broadcast index in the routing information, use that.
Conveniently, a zero index is the same as the old NULL test.
Rename struct node's announcement_idx to node_announce_msgidx to
make it match the other users.

We tal_dup_arr() it, which does take. Make it const in the structure;
the tal_dup_arr() removes the const, so it compiles without it, but it's
misleading.

We only access via index. We do, however, want to clean up when we
delete nodes and channels, so we tie lifetimes to that. This leads
us to put the index into 'struct queued_message'.

1. make queue_peer_msg() use both if branches, as both equally likely.
2. Remove redundant *scid = NULL in handle_channel_announcement.
3. Log failing pending channel_updates.

As per BOLT #7.
We don't do this for channel_update which are queued because the
channel_announcement is pending though.

If the channel is pending, we queue the node_announcment and if the channel
is OK we re-call process_node_announcement. Make sure that second call
won't fail if the first succeeded.

Improve usability in these scenarios:
* bitcoin-cli not available in PATH and/or bitcoind not running
* bitcoin-cli available in PATH but bitcoind is not running
We say "in N blocks" but we actually mean "N blocks after this tx" which is
actually N-1 or less. Change wording and tighten tests which misunderstood
this.
Also, the 'assert not l1.daemon.is_in_log('onchaind complete, forgetting peer')'
are unlikely to work until the daemon has actually seen the block, so add
sync_blockheight before all of those.
These changes reveal some sloppy testing, which we fix.

With the following patch applied, we could clearly see onchaind try to
broadcast the timeout tx one block too early:
sendrawtx exit 26, gave error code: -26?error message:?non-final (code 64)?
This is because of an out-by-one error in calculating the relative
depth required, since the out->tx_blockheight is already 1 before the
current block.

This was revealed in #1114; onchaind isn't actually completely idempotent
due to fee changes (and the now-fixed change in keys used).
This triggers the bug by restarting with different fees, resulting in
onchaind not recognizing its own proposal:
