* Fix usage of `echo "...\n..."` (without `-e`), generating a
broken output:
```
lightningd-config <lightningd-config.5.md>
lightningd\nlightning-autocleaninvoice.7.md <lightningd.8.md\nlightning-autocleaninvoice.7.md>
```
* Use `$(SORT)` instead of bare `sort` to avoid locale-dependent sort.
* Strip the trailing .[0-9].md without invoking sed.
* Sort all man pages as one block.
Changelog-None
Put `LC_ALL=C sort` in a variable and use it everywhere. It was
forgotten in one place.
Without `LC_ALL=C` it would order `a.b` before `a-c` even though
`. (0x2E)` > `- (0x2D)`.
Changelog-None
This sets the nLockTime to the tip (and accordingly each input's nSequence to
0xfffffffe) for withdrawal transactions.
Even if the anti fee-sniping argument might not be valid until some time yet,
this makes our regular wallet transactions far less distinguishable from
bitcoind's ones since it now defaults to using native Segwit transactions
(like us). Moreover other wallets are likely to implement this (if they
haven't already).
Changelog-Added: wallet: withdrawal transactions now sets nlocktime to the current tip.
GCC 10 defaults to `-fno-common`. no longer automatically sharing
global variable definitions, which makes it important to define
them in only one place (otherwise there will be duplicate definition
errors). Add `extern` qualifiers where (I think) is the best place for
them.
ChangeLog-Fixed: Clarified about connection in documentation. Also, `fundchannel` already `connect`s if your node knows how to contact the desired peer for a few versions now, so clarify documentation about this as well.
We are about to disect a couple of invoices for features, so let's add a class
that can encode and decode invoices from bolt11 strings. This is pretty much
the lnaddr.py file created by @rustyrussell with some minor changes. I'm
planning to clean this up further which is why I'm only exporting the
`Invoice` class for now.
Using it with a different value to the amount sent causes a crash in 0.8.0,
which is effectively deprecating it, so let's disallow it now.
Changelog-Changed: If the optional `msatoshi` param to sendpay for non-MPP is set, it must be the exact amount sent to the final recipient.

We also update since the merged version sets feature bit 9 (as it's
supposed to now that we tied that to payment_secret).

We tag them with specific versions when they're experimental,
but do a poor job of cleaning them up (and thus ensuring they're
checked!) afterwards.

Before this patch we used `int` for error codes. The problem with
`int` is that we try to pass it to/from wire and the size of `int` is
not defined by the standard. So a sender with 4-byte `int` would write
4 bytes to the wire and a receiver with 2-byte `int` (for example) would
read just 2 bytes from the wire.
To resolve this:
* Introduce an error code type with a known size:
`typedef s32 errcode_t`.
* Change all error code macros to constants of type `errcode_t`.
Constants also play better with gdb - it would visualize the name of
the constant instead of the numeric value.
* Change all functions that take error codes to take the new type
`errcode_t` instead of `int`.
* Introduce towire / fromwire functions to send / receive the newly added
type `errcode_t` and use it instead of `towire_int()`.
In addition:
* Remove the now unneeded `towire_int()`.
* Replace a hardcoded error code `-2` with a new constant
`INVOICE_EXPIRED_DURING_WAIT` (903).
Changelog-Changed: The waitinvoice command would now return error code 903 to designate that the invoice expired during wait, instead of the previous -2

If the same memory gets reallocated, our "has the tip changed?" test
gets a false negative. This happened for me about one time in 10,
causing tests/test_misc.py::test_funding_reorg_remote_lags to fail.

This shouldn't happen if channeld is working properly, but I'm going to
change that, and this current code means we stop responding at that point
(not every failpath in peer_accepted_htlc() called channel_internal_error).

1. We asserted that there wouldn't be a raw failcode.
2. We didn't pass the failure information via JSON in this case.

We could use sendonion to do this, but it actually takes a different path through
pay, and I wanted to test all of it, so I made a new dev flag.
We currently get upset with the response:
lightningd/pay.c:556: payment_failed: Assertion `!hout->failcode' failed.

This completes the custommsg epic, finally we are back where we began all that
time ago (about 4 hours really...): in a plugin that implements some custom
logic.
This is mainly meant as a marker so that we can later remove the code if we
decide to make the handling of custommsgs a non-developer option. It marks the
place that we would otherwise handle what in dev-mode is a custommsg.
This solves a couple of issues with the need to synchronously drop the
connection in case we were required to understand what the peer was talking
about while still allowing users to experiment, just not kill connections.
We cannot let users use `sendcustommsg` to inject messages that are handled
internally since it could result in our internal state tracking being borked.
This command injects a custom message into the encrypted transport stream to
the peer, allowing users to build custom protocols on top of c-lightning
without requiring any changes to c-lightning itself.
This is currently in opening_control since that's the only part that has
access to the uncommitted_channel internals. Otherwise it's independent from
the specific daemon.
These messages may be exchanged between the master and any daemon. For now
these are just the daemons that a peer may be attached to at any time since
the first example of this is the custommsg infrastructure.
The `generate` has been deprecated since 0.16 and has been removed in 0.18.0
so we better use `generatetoaddress` instead, which is already what we do with
`bitcoind`. So we remove the override here.
Since we now compute the hash while deserializing the block header we can now
just use it, no reason to serialize the header just to hash it again. This
also allows us to throw away all the added dynafed fields in the next commit
instead of having to carry them around.
This avoids having to re-serialize the block header just to compute the
hash. It also frees us from having to carry around all the details in the
header and we can hand around a minimal version.
