New codes: FUND_MAX_EXCEEDED, FUND_CANNOT_AFFORD, FUND_DUST_LIMIT_UNMET.
The error message "Cannot afford fee" was not exactly correct because
it would also occur if the amount requested could not be afforded. So
I changed it to the more generic "Cannot afford transaction".
Other things:
* Fixed off-by-one satoshi in fundchannel manpage.
* Changed 'arror' to 'error' because we are not pirates.
Turn req_running into a pointer to the current bcli structure, which means
the leak detection can find it.
Also suppress leaks in the case where we're only attached to a timer

During a meeting earlier this week we agreed with Eclair to temporarily
increase the final CLTV delta in our invoices to establish
compatibility with the already deployed Eclair wallets. They in turn
agreed to remove the enforcement of higher final CLTV deltas, or bump
it locally should it not match their expectations as allowed by
BOLT 11. This has since been implemented in ACINQ/eclair#627.
satoshis.place was slowing to a crawl, c-lightning was unresponsive.
Logs revealed charged doing many, many listinvoice <label> RPCs.
We were iterating the entire db every time: stop that!

The fee range can sometimes cause channels to be closed when the estimator
jumps. This has been the case a few times in the last months, and causes a
number of channels to be closed, and issue reports to be filed.
Increasing this from 5x to 10x should get rid of 84%+ of these
closures (measured based on 1h windows over the last 6 months and assuming
worst case situations).

I still believe that 2 weeks is way too much, but we were promised that these
defaults would be slowly reduced to saner values as the stability increases.

Compares the `blocknum` in the `short_channel_id` with the range of blocks we
store in the database and abort if we should have known about it. Avoids
bombarding `bitcoind` with requests for channels that have already been spent or
were invalid in the first place.

Since we currently only (ab)use it to send everything, we need a way to
generate boutique queries for testing.

We're telling gossipd about disconnections anyway, so let's just use that signal
to disable both sides of the channel.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
This was failing some of our integration tests, i.e., the ones closing a channel
and not waiting for sigexchange. The remote node would often not be quick enough
to send us its disabling channel_update, and hence we'd still remember the
incoming direction. That could then be sent out as part of an invoice, and fail
subsequently. So just set both directions to be disabled and let the onchain
spend clean up once it happens.

Until now, `command_fail()` reported an error code of -1 for all uses.
This PR adds an `int code` parameter to `command_fail()`, requiring the
caller to explicitly include the error code.
This is part of #1464.
The majority of the calls are used during parameter validation and
their error code is now JSONRPC2_INVALID_PARAMS.
The rest of the calls report an error code of LIGHTNINGD, which I defined to
-1 in `jsonrpc_errors.h`. The intention here is that as we improve our error
reporting, all occurenaces of LIGHTNINGD will go away and we can eventually
remove it.
I also converted calls to `command_fail_detailed()` that took a `NULL` `data`
parameter to use the new `command_fail()`.
The only difference from an end user perspecive is that bad input errors that
used to be -1 will now be -32602 (JSONRPC2_INVALID_PARAMS).
This resolves the problem where both channeld and gossipd can generate
updates, and they can have the same timestamp. gossipd is always able
to generate them, so can ensure timestamp moves forward.

Because we have too many which are never used and I don't want to document
them.
1. Remove unused anchor_onchain_wait. When implemented, it should be
hardcoded to 100 or more.
2. Remove anchor_confirms_max. 10 always reasonable, and we can readd
an override option should someone need it.
3. max_htlc_expiry should be the same as locktime_max (which increases
from 3 to 5 days by default): they're both a limit on how long
funds can be locked up.
4. channel_update_interval should always be a dev option.

Make --override-fee-rates a dev option. We use default-fee-rate in
its place, which (since bitcoind won't give fee estimates in regtest
mode for short chains) gives an effective feerate of 15000/7500/3750.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We never hit the guess_feerate() path, because we turned a 0 ("can't
estimate fee") into 253.
This also revealed that we weren't initializing topo->feerate, and
that we were giving spurious updates even if we were using override-fee-rates.

Just have a "new depth" callback, and let channeld do the right thing.
This makes the channeld paths a bit more straightforward.

Tor wasn't actually working for me to connect to anything, but it worked
for 'ssh -D' testing.
Note that the resulting 'netaddr' is a bit weird, but I guess it's honest.

This is useful for the next patch, where we want to hand the unresolved
name through to the proxy.
This also addresses @Saibato's worry that we still called getaddrinfo()
(with the AI_NUMERICHOST option) even if we didn't want a lookup.
