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

channeld can't do it any more: it's using local sockets. Connectd

Instead of passing the incoming socket to lightningd for the
subdaemon, create a new one and simply shuffle data between them,
keeping connectd in the loop.
For the moment, we don't decrypt at all, just shuffle. This means our
buffer code is kind of a hack, but that goes away once we start
actually decrypting and understanding message boundaries.
This implementation is naive: it closes the socket to the local daemon
as soon as the peer closes the socket to us. This is fixed in a
successive patch series (along with many other similar issues).

WebSocket is a bit weird:
1. It starts like an HTTP connection, but they send special headers.
2. We reply with special headers, one of which involves SHA1 of one of theirs.
3. We are then in WebSocket mode, where each frame starts with a 2-20 byte
header.
We relay data in a simplistic way: if either side sends something, we
read it and relay it synchronously. That avoids any gratuitous
buffering.

Took me a while (stressing under valgrind) to reproduce this,
then longer to figure out how it happened.
Turns out io_new_conn() can fail if the init function fails.
In our case, this can happen if connect() immediately returns
an error (inside io_connect). But we've already set the finish
function, which (if this was the last address), will free connect,
making the assignment `connect->conn = ...` write to a freed address.
Either way, if it fails, try_connect_one_addr() has taken care to
update connect->conn, or free connect, and the caller should not do it.

This is a common thing to do, so create a macro.
Unfortunately, it still needs the type arg, because the paramter may
be const, and the return cannot be, and C doesn't have a general
"(-const)" cast.

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.
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.
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
This makes it clear we're dealing with a message which is a wrapped error
reply (needing unwrap_onionreply), not an already-wrapped one.

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).
Changelog-None
The tor proxy might want auth 0x2 or answer what ever not defined
in https://tools.ietf.org/html/rfc1928.
Changelog-Fixed: TOR: We don't send any further request if the return code of connect is not zero or error.
Signed-off-by: Saibato <saibato.naga@pm.me>
For example:
"Tor connect out for host example.com error: 4 "
becomes:
"Error connecting to example.com: Tor server reply: host unreachable"
Also clarify the error:
"Connected out for example.com error"
to:
"Connected out for example.com error: authentication required"
because the only reason it could have failed is that the Tor socks5
server did not like any of our proposed auth methods and we only
proposed "no auth".
Changelog-None
We want to have a static Tor service created from a blob bound to

The spec is (RSN!) going to explicitly denote where each feature should
be presented, so create that infrastructure.
Incorporate the new proposed bolt11 features, which need this.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This was decided at a recent spec meeting: in particular, mpp and
var_onion_optin options will be used here.
We enhanced "features_supported" into "features_unsupported" so it
can return the first un-handlable bit number.

This is ignored in subdaemons which are per-peer, but very useful for
multi-peer daemons like connectd and gossipd.

Even if it is on startup only once ...
Like @bitcoin-software indicated the expected UX should be in
line with what a user expects the software will do
so we should not dns if we say so with a flag that suggest that.
Changelog-Fixed: We disable all dns even on startup the scan for bogus dns servers, if --always-use-proxy is set true

I was wondering why TAGS was missing some functions, and finally
tracked it down: PRINTF_FMT() confuses etags if it's at the start
of a function, and it ignores the rest of the file.
So we put PRINTF_FMT at the end, but that doesn't work for
*definitions*, only *declarations*. So we remove it from definitions
and add gratuitous declarations in the few static places.1
