I split the peer_connected() function into the peer_reconnected(),
which is basically an entire separate path from the rest of
peer_connected().
Also, removed unused TAKEN annotation from `id` parameter. Nobody actually
hands us take() there, and just as well, since we don't take it!

connectd is the only user of the cryptomsg async APIs; better to
open-code it here. We need to expose a little from cryptomsg(),
but we remove the 'struct peer' entirely from connectd.
One trick is that we still need to defer telling lightningd when a
peer reconnects (until it tells us the old one is disconnected). So
now we generate the message for lightningd and send it once we're woken.

We only call it once, so don't free the "old" one. And fix some indenting.

We're about to slow down the invoice rpc (esp. under valgrind), which
breaks the delicate timing of the autocleaninvoice test.
Change that so the autocleaner (and timestamp) starts after the invoices
are added.

We do this a lot, and had boutique helpers in various places. So add
a more generic one; for convenience it returns a pointer to the new
end element.
I prefer the name tal_arr_expand to tal_arr_append, since it's up to
the caller to populate the new array entry.

We have a lot of infrastructure to delay local channel_updates to
avoid spamming on each peer reconnect; we had to keep tracking of
pending ones though, in case we needed the very latest for sending an
error when failing an HTLC.
Instead, it's far simpler to set the local_disabled flag on a channel
when we disconnect, but only send a disabling channel_update if we
actually fail an HTLC.
Note: handle_channel_update() TAKES update (due to tal_arr_dup), but we
didn't use that before. Now we do, add annotation.

We trade channel_update before channel_announce makes the channel
public, and currently forget them when we finally get the
channel_announce. We should instead apply them, and not rely on
retransmission (which we remove in the next patch!).
This earlier channel_update means test_gossip_jsonrpc triggers too
early, so have that wait for node_announcement.

It's simpler and more robust to just check that it's not yet announced

I wanted to add run-secret_eq_consttime and run-find_my_abspath to the
.gitignore file, but instead I replaced all the names of tests with a simple
regex.
This works because git doesn't ignore files that are already in git. So
source and header file are safe. It doesn't ignore *.c files that haven't been
added to git either.

The help command now adds command usage to its output by calling each
command handler in CMD_USAGE mode.
Instead of seeing, for example:
decodepay
Decode {bolt11}, using {description} if necessary
we see:
decodepay bolt11 [description]
Decode {bolt11}, using {description} if necessary

Callers to param() can now optionally set a flag to see if command_fail was
called.
This is necessary because the `cmd` is freed in case of failure.
I spent a bit of time trying to extend the lifetime of the `cmd` to the end
of parse_request(), but the destructors still needed to be called when they
were, and it was getting ugly. So I took this minimal approach.

Now call param() even for commands that don't accept any parameters.
This is a bugfix of sorts. For example, before you could call:
bitcoin-cli getinfo blah
and the blah parameter would be ignored.
Now you will get an error: "too many parameters: got 1, expected 0"

Added the concept of a "command mode". The
behavior of param() changes based on the mode.
Added and tested the command mode of CMD_USAGE for
setting the usage of a command without running it.
Only infrastructure and test. No functional changes.

It turns out we were heavily relying on the fact that after each message from
the client there'd be a flush, and that there would not be anything after the
JSON object we read. This will no longer be the case once we start streaming
things or we are very quick in issuing the JSON-RPC requests.
This just takes one of the error paths (incomplete read) and makes it into a
successful path if we have indeed read a full root element.
Incrementing version number means stores which were prior to the previous
commit will be removed, and refreshed. The simplest fix, if not the most
efficient.

We extract the tx from the logs, and then we wait until that hits
the mempool. This is more reliable than 'sendrawtx' in the logs,
which might catch a previous sendrawtx; it's also more explicit
that we expect that tx exactly.

BOLT 7's been updated to split the flags field in `channel_update`
into two: `channel_flags` and `message_flags`. This changeset does the
minimal necessary to get to building with the new flags.
We used to use it to complain about bad requests, but we use the status conn
now, so it's unused except for tests and asserts.
