1. Make it the standard "return the error" pattern.
2. Rather than flags to indicate what types are allowed, have the callers
check the return explicitly.
3. Document the APIs.

Most of this is piping the flag through so we know it's a websocket!

Per BIP-0171, the signature map is of pubkey to "The signature as would
be pushed to the stack from a scriptSig or witness".

I removed these prematurely: we *haven't* had a release since
introducing them!
This consists of reverting d15d629b8b
"plugins/fetchinvoice: remove obsolete string-based API." and
plugins/fetchinvoice: remove obsolete string-based
API. "onion_messages: remove obs2 support."
Some minor changes due to updated fromwire_tlv API since they
were removed, but not much.

Changelog-EXPERIMENTAL: REVERT: Removed backwards compat with onion messages from v0.10.1.
We don't need to log msgs from subds, but we do our own, and we weren't.
1. Rename queue_peer_msg to inject_peer_msg for clarity, make it do logging
2. In the one place where we're relaying, call msg_queue() directly.

connectd will be keeping the conn open, so it needs to free this
"conn_timeout" timer. Pass it through, so we can do that.

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.

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).

We should actually be including this (as it may define _GNU_SOURCE
etc) before any system headers. But where we include <assert.h> we
often didn't, because check-includes would complain that the headers
included it too.
Weaken that check, and include config.h in C files before assert.h.

Avoids much cut & paste. Some tests don't need any of it, but most

We create ALL_PROGRAMS, ALL_TEST_PROGRAMS, ALL_C_SOURCES and
ALL_C_HEADERS. Then the toplevel Makefile knows which are
autogenerated (by wildcard), so it can have all the rules to clean
them or check the source as necessary.

We don't preserve detailed asset information at the moment, so provide a
way to convert from a sat to an amount_asset struct.
We also need a way to convert from an 'amount_asset' to a 'value' for
elements, which for explicit (i.e. non-blinded) asssets is a 0x01 prefix
plus the big-endian encoded value.
Our existing coin_moves tracking logic assumed that any tx we had an
input in belonged to *all* of our wallet (not a bad assumption as long
as there was no way to update a tx that spends our wallets)
Now that we've got `signpsbt` implemented, however, we need to be
careful about how we account for withdrawals. For now we do a best guess
at what the feerate is, and lump all of our spent outputs as a
'withdrawal' when it's impossible to disambiguate
It returns NULL, so you can simply `return fromwire_fail(...)`
if you want to return NULL in this case. Use that more.

We did this originally because these types are referred to in the bolts, and we
had no way of injecting the correct include lines into those. Now we do, so
there's less excuse for this.

Note that it's channeld which calculates the shared secret, too. This
minimizes the work that lightningd has to do, at cost of passing this
through.
We also don't yet save the blinding field(s) to the database.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
common/onion is going to need to use this for the case where it finds a blinding
seed inside the TLV. But how it does ecdh is daemon-specific.
We already had this problem for devtools/gossipwith, which supplied a
special hsm_do_ecdh(). This just makes it more general.
So we create a generic ecdh() interface, with a specific implementation
which subdaemons and lightningd can use.

Turns out that unnecessary: all callers can access the feature_set,
so make it much more like a normal primitive.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This will help with the next patch, where we wean off using a global
for features: connectd.c has access to the feature bits.
Since connectd might now want to send a message, it needs the crypto_state
non-const, which makes this less trivial than it would otherwise be.

This is to prepare for dynamic features, including making plugins first

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.
This is ignored in subdaemons which are per-peer, but very useful for
multi-peer daemons like connectd and gossipd.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Currently the only source for amount_asset is the value getter on a tx output,
and we don't hand it too far around (mainly ignoring it if it isn't the
chain's main currency). Eventually we could bubble them up to the wallet, use
them to select outputs or actually support assets in the channels.
Since we don't hand them around too widely I thought it was ok for them to be
pass-by-value rather than having to allocate them and pass them around by
reference. They're just 41 bytes currently so the overhead should be ok.
