1. Allow timers to be freed in their callback.
2. Clarify in header that we have to terminate our timer with timer_finished()
eventually.
3. We don't currently have plugins with more than one outstanding timer, but
it certainly would be possible, so fix in_timer to be a counter.

New fields don't have to be spelled out twice.
The raw version are called _only, so we don't miss a call
accidentally. We can rename them when we finally deprecated old

Instead of lightningd telling us when it's ready, we ask it.

The original idea is to "tal" channel on the "ctx"(In fact, we'd like to set ctx as "ld").
But we already tal channel on "ld" in new_channel(), so "ctx" is unused.
My raspberry pi node hung up on my other node:
lightning_openingd-... chan #1: Got bad message from gossipd: 0db1
This is because we didn't handle that message in one path.

We check that memcmp *isn't* constant time, but that's only true under
-O2 or above: __OPTIMIZE__ doesn't distinguish.
So we need a finer-grained test. Also reduce verbosity by default.

Unfortuntely we get spurious uninitialized variable warnings with

We try to look up the funding tx, but it's already spent that to fund
the channel, so we need txindex if this test is to work reliably.

Instead of reading the store ourselves, we can just send them an
offset. This saves gossipd a lot of work, putting it where it belongs
(in the daemon responsible for the specific peer).

We need to store the channel capacity for channel_announcement: hand it
in directly rather than having the gossip_store code do a lookup.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Save some overhead, plus gets us ready for giving subdaemons direct
store access. This is the first time we *upgrade* the gossip_store,
rather than just discarding.
The downside is that we need to add an extra message after each
channel_announcement, containing the channel capacity.

For performance reasons we start the lightningd instances in
parallel. However, if we only assign the numeric ids (used for log-prefixes
and home directories) when we are already running in parallel, we are not
guaranteed to get the numeric ids matching the return value of `get_nodes` or
`line_graph`. With this patch we now select numeric ids before parallelizing
the start.

Here I add the test for this 5 local_failed case in this commit.
There 5 cases for FORWARD_LOCAL_FAILED status:
1. When Msater resolves the reply about the next peer infor(sent by Gossipd), and need handle unknown next peer failure in channel_resolve_reply();
2. When Master handle the forward process with the htlc_in and the id of next hop, it tries to drive a new htlc_out but fails in forward_htlc();
3. When we send htlc_out, Master asks Channeld to add a new htlc into the outgoing channel but Channeld fails. Master need handle and store this failure in rcvd_htlc_reply();
4. When Channeld receives a new revoke message, if the state of corresponding htlc is RCVD_ADD_ACK_REVOCATION, Master will tries to resolve onionpacket and handle the failure before resolving the next hop in peer_got_revoke();
5. When Onchaind finds the htlc time out or missing htlc, Master need handle these failure as FORWARD_LOCAL_FAILED in if it's forward payment case.
