For example, if you do:
```
./lightningd/lightningd --network=regtest --experimental-websocket-port=19846
```
Then you're trying to reuse the normal port as the websocket port, but this
only fails at *listen* time, when we activate connectd. Catch this too.
Fixes incorrect fatal() message, too.

Changelog-Changed: JSON_RPC: `sendcustommsg` now works with any connected peer, even when shutting down a channel.
We want to stream gossip through this, but currently connectd treats the
fd as synchronous. While we work on getting rid of that, it's easiest to
have two fds.

It's weird to have connectd ask gossipd, when lightningd can just do it
and hand all the addresses together.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We now let gossipd do it.
This also means there's nothing left in 'struct per_peer_state' to
send across the wire (the fds are sent separately), so that gets
removed from wire messages too.

We actually intercept the gossip_timestamp_filter, so the gossip_store
mechanism inside the per-peer daemon never kicks off for normal connections.
The gossipwith tool doesn't set OPT_GOSSIP_QUERIES, so it gets both, but
that only effects one place.

As connectd handles more packets itself, or diverts them to/from gossipd,
it's the only place we can implement the dev_disconnect logic.

And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).
config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

If the port is set, we spawn it (lightning_websocketd) on any
connection to that port. That means websocketd is a per-peer daemon,
but it means every other daemon uses the connection normally (it's
just actually talking to websocketd instead of the client directly).

This renames all occurences of use_proxy_always to always_use_proxy
to keep it inline with config values. This was a bit confusing.
Only significant change is that the payload in the plugins init
requests also contained the old name. No plugin currently seems to make
use of this variable yet. The old name 'use_proxy_always' is added when
deprecated APIs is enabled.
Changelog-Deprecated: Plugins: Renames plugin init 'use_proxy_always' to 'always_use_proxy'
Currently we abuse openingd and dualopend to do this, but connectd already

Trying to put all the disconnect logic into the same path was a dumb
idea. If you asked to reconnect but passed in an 'unsaved' channel, we
would not call the 'reconnect' code.
Instead, we make a differentiation between "unsaved" channels
(ones that we haven't received commitment tx for) and handle the
disconnect for these separate from where we want to do a reconnect.
This means remembering the connection direction. We also use the address to try
to reconnect, which we shouldn't bother with if they connect to us.
For peers from the database, we currently always save the addr: we shouldn't really
do this if they connected to us, since it's not useful for reconnecting (we don't
show the addr in JSON reply to listpeers unless we're connected, so it's only an
internal issue). This is left for future work.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This matters: if we connected, the address is probably usable for future connections.
But if they connected, the port is probably not (but the IP address may be).

Changelog-Added: JSON: `connect` returns `features` of the connected peer on success.
The `init_featurebits` are computed at startup, and then cached
indefinitely. They are then used whenever a new `init` handshake is performed.
We could add a new message to push updates to `connectd` whenever a plugin is
added or removed, but that's up for discussion.
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
Add towire_int() and fromwire_int() functions to "(de)serialize"
"int". This will only work as long as both the caller of towire_int()
and the caller of fromwire_int() use the same in-memory representation
of signed integers and have the same sizeof(int).
