This simplifies the dependencies:
1. Objs depend on headers, not other objs.
2. Programs depend on objs.
3. A .o file will generally implicitly depend on the .c file it's built from.
4. If a file has a build line, it's often better to list all deps there.
5. I spotted some missing 'make clean' files.
The particular problem in this case seems to be that make would use
tools/test/gen_test.c before it was ready. It's probably confused by
the use of recursive make via update-mocks, so explicitly split that
into two stages.

Dynamic plugins were keeping fds open; they should not have these
at all anyway, but worse, they interfere with operation because
we don't notice they're closed.
The symptom was that shutdown of the test_plugin_slowinit and
test_plugin_command was 30 seconds (10 seconds grace to kill each daemon).

I don't remember ever seeing a bug which only showed up in VALGRIND=1 with developer
mode disabled, so don't test that, and spread out the other test more evenly.
In addition, disable the worst-performing tests in DEVELOPER=0 mode.

This is probably worth preventing.
1. Our depth estimate would be inaccurate possibly leading to us
timing out too early.
2. If we're not up-to-date our onchain funds are unknown.
3. We wouldn't be able to send or receive HTLCs until we're synced anyway.

We want to still allow incoming connections, and reestablishment of
channels, but if one tries to give us an HTLC, stall until we're
synced.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
If we don't know block height, we shouldn't be sending HTLCs. This
stops us forwarding HTLCs as well as new payments.

You're supposed to be able to hand mock_rpc either a function to call,
or a dict canned response. We never did the latter, and the logic
was broken.
It was testing the key, not the value for whether it was a dict. And
it could never have given a valid response anyway, since it wouldn't
know the id to use. So assume it's a successful result.

0. Add an index
1. Mention regtest early on.
2. Link to doc/INSTALL.md for build-it-yourself.
Since they're reading this doc, they're probably already on GH so don't discourage it.
3. Talk about contrib/startup_regtest.sh.
4. Use mainnet in the examples, since that's what people probably want.
5. Refer to default .lightning dir, and manpage.
6. Trim the JSON-API section down to simple commands.
7. Add section on getting started: bootstrap script and plugins.
8. Less details on config files, just refer to the man page.

If l2 doesn't think we're onchain yet, it treats the new connection from l1
as a reconnection, triggering 'ValueError: 1 nodes had unexpected reconnections'

I suspect multiple plugins trying to connect at the same
time are overrunning the 1-deep listen queue:
From man listen(2):
The backlog argument defines the maximum length to which the queue of
pending connections for sockfd may grow. If a connection request ar‐
rives when the queue is full, the client may receive an error with an
indication of ECONNREFUSED

These both allow us to reproduce the test vectors in the next patch. But
using Z_DEFAULT_COMPRESSION is a reasonable idea anyway.

Make the TLV element a simple array. This is a bit neater, in fact, and

In fact, we always generate them, we only send them if asked. And we set
the flags to 0 if not --enable-experimental-features, so we never send in
that case.
Generating checksums involves pulling the channel_update from the
gossip_store, which is suboptimal: there's a FIXME to store the
checksum in memory.

We're about to use the for gossip extended info too, which *don't* put
the encoding byte at the beginning of the data stream. So this removes
some "scids" from function names and separates out the "prepend a byte"
case from the "external encoding_type" case.

These indicate what fields we are to return. If there's now TLV, or we
haven't got --enable-experimental-features, it's set to all 1s so behaviour
is unchanged.

We haven't touched the readme for quite some time, just randomly added to it,
and it's starting to show. This is my attempt at cleaning it up a bit (more to
come):
- No longer discourage users from running on mainnet, we're way beyond that
point.
- No longer instruct users to build from source, when we have real binary
releases, on the PPA, the releases page and the docker images.
- Cut down on the docker specific instructions, they are taking a lot of room
when only a minority will likely run them that way
- Generally make the README more of a dispatch for more in-depth
documentation rather than trying to address everything right on the
front-page.
- Add a bit of context about running on top of a pruned node

`close` takes two optional arguments: `force` and `timeout`.
`timeout` doesn't timeout the close (there's no way to do that), just
the JSON call. `force` (default `false`) if set, means we unilaterally
close at the timeout, instead of just failing.
Timing out JSON calls is generally deprecated: that's the job of the
client. And the semantics of this are confusing, even to me! A
better API is a timeout which, if non-zero, is the time at which we
give up and unilaterally close.
The transition code is awkward, but we'll manage for the three
releases until we can remove it.
The new defaults are to unilaterally close after 48 hours.
Fixes: #2791

We're about to change the API, so this makes the tests still work
across the transition (and, as a bonus, tests our backwards compat
shim).
