Rusty Russell 2962b93199 pytest: don't assume disconnect finished atomically, and suppress interfering redirects.
In various places, we assumed that when `connected` is false,
everything is finished.  This is not true: we should wait for the
state we expect.

In addition, various places allows reconnections, which interfered
with the logic; suppress them.

Rusty Russell 9685c1adaf lightningd: remove getsharedsecret.
This was introduced to allow creating a shared secret, but it's better to use
makesecret which creates unique secrets.  getsharedsecret being a generic ECDH
function allows the caller to initiate conversations as if it was us; this
is generally OK, since we don't allow untrusted API access, but the commando
plugin had to blacklist this for read-only runes explicitly.

Since @ZmnSCPxj never ended up using this after introducing it, simply
remove it.

Rusty Russell d2952576cd pyln-testing: restore proper streaming behaviour for lightningd.
Get it to log direct to stdout, so we see what's happening *as it
happens* rather than as we read it.  We could restore the thread we
were using before, but that added more problems than it solved.

This means that we need the hsm password prompts in the log though.

Rusty Russell a0e0dbf229 pyln-testing: use files for stdout and stderr, not threads.
Some flakes are caused by weird races in this code.  Plus, if we
get things to write straight to files, we might see things in
there on post-mortem which happen after the python runner exits.

It's a bit less efficient, but much simpler.  Let's see if it helps!

Some tests need a rework now, since we don't get a failure (except
eventual timeout), but they're simpler.

niftynei d2c4d4aec2 coin_mvts: rewrite how onchain events are recorded, update tests
The old model of coin movements attempted to compute fees etc and log
amounts, not utxos. This is not as robust, as multi-party opens and dual
funded channels make it hard to account for fees etc correctly.

Instead, we move towards a 'utxo' view of the onchain events. Every
event is either the creation or 'destruction' of a utxo. For cases where
the value of the utxo is not (fully) debited/credited to our account, we
also record the output_value. E.g. channel closings spend a utxo who's
entire value we may not own.

Since we're now tracking UTXOs onchain, we can now do more complex
assertions about the onchain footprint of them. The integration tests
have been updated to now use more 'chain aware' assertions about the
ending state.

Rusty Russell d8e68893f5 bcli: become less aggressive with onchain fee levels.
Users are more upset recently with the cost of unilateral closes
than they are the risk of being cheated.  While we complete our
anchor implementation so we can use low fees there, let's
get less aggressive (we already have 34 or 18 blocks to close
in the worst case).

The changes are:

- Commit transactions were "2 CONSERVATIVE" now "6 ECONOMICAL".
- HTLC resolution txs were "3 CONSERVATIVE" now "6 ECONOMICAL".
- Penalty txs were "3 CONSERVATIVE" now "12 ECONOMICAL".
- Normal txs were "4 ECONOMICAL" now "12 ECONOMICAL".

There can be no perfect levels, but we have had understandable
complaints recently about how high our default fee levels are.

Rusty Russell 2696ec6ccb pytest: fix assumptions in test_withdraw_misc
First, simplify: amount is set to 1000000, but then we deposit 1000000 + 0.01btc
(i.e. 2000000), and we always use 2 * amount.  Just use a single constant to
make it clear.

Secondly, we assume that the wallet considers outputs spent as soon as
we created the tx: this will not be true once withdraw uses sendpsbt.
So, we generate blocks, but now sometimes withdraw will pick up change
txs, so we need to reserve them to avoid that messing our coinmovements.

Finally, we assumed the withdrawl order was BIP69, which becomes
variable.

darosior 8a3295b6a8 chaintopology: Add the cost of HTLCs transactions to json_feerates
Changelog-Changed: "htlc_timeout_satoshis" and "htlc_success_satoshis" fields have been added to the `feerates` command.

darosior d4fe4073a4 lightning/bitcoind: adapt and batch fees estimations
This adapts our fee estimations requests to the Bitcoin backend to the
new semantic, and batch the requests.

This makes our request for fees much simpler, and leaves some more
flexibility for a plugin to do something smart (it could still lie before
but now it's explicit, at least.) as we don't explicitly request
estimation for a specific mode and a target.

Changelog-Changed: We now batch the requests for fee estimation to our Bitcoin backend.
Changelog-Changed: We now get more fine-grained fee estimation from our Bitcoin backend.

darosior dce2e87928 chaintopology: better feerate targets differentiation
We kept track of an URGENT, a NORMAL, and a SLOW feerate. They were used
for opening (NORMAL), mutual (NORMAL), UNILATERAL (URGENT) transactions
as well as minimum and maximum estimations, and onchain resolution.

We now keep track of more fine-grained feerates:
- `opening` used for funding and also misc transactions
- `mutual_close` used for the mutual close transaction
- `unilateral_close` used for unilateral close (commitment transactions)
- `delayed_to_us` used for resolving our output from our unilateral close
- `htlc_resolution` used for resolving onchain HTLCs
- `penalty` used for resolving revoked transactions

We don't modify our requests to our Bitcoin backend, as the next commit
will batch them !

Changelog-deprecated: The "urgent", "slow", and "normal" field of the `feerates` command are now deprecated.
Changelog-added: The fields "opening", "mutual_close", "unilateral_close", "delayed_to_us", "htlc_resolution" and "penalty" have been added to the `feerates` command.

ZmnSCPxj jxPCSnmZ d9b2482415 lightningd/hsm_control.c: Implement `getsharedsecret`.
ChangeLog-Added: New `getsharedsecret` command, which lets you compute a shared secret with this node knowing only a public point. This implements the BOLT standard of hashing the ECDH point, and is incompatible with ECIES.

Rusty Russell 40e3566e9a lightningd: use the async mechanism for channel_update access.
Instead of saving a stripped_update, we use the new
local_fail_in_htlc_needs_update.

One minor change: we return the more correct
towire_temporary_channel_failure when the node is still syncing.

darosior bbc5c10919 pytest: adjust mocks and logs for bitcoind
For bitcoind_fail_first:
We only ever send `getblock` if we got a successful block hash from
`getblockhash`, and if we can't get the block in that case it means
our Bitcoin backend is faulty and we shouldnt continue.

So, mock `getblockhash` instead, which is authorized to spuriously fail.

For both bitcoind_fail_first and bitcoind_failure:
Adapt the logs.

Rusty Russell c11212bb52 pytest: test that we handle WIRE_UPDATE_FAIL_MALFORMED_HTLC correctly.
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.

ZmnSCPxj 54cc735201 lightningd/peer_control.c: Implement waitblockheight.
This is needed to fully implement handling of blockheight disagreements
between us and payee.
If payee believes the blockheight is higher than ours, then `pay`
should wait for our node to achieve that blockheight.

Changelog-Add: Implement `waitblockheight` to wait for a specific blockheight.

Christian Decker 8cad3ffeac pyln: Work around the socket path length on Linux OSs
Some Linux OSs impose a length limit on the path a Unix socket may have. This
is not an issue in `lightningd` since we `chdir()` into that directory before
opening the socket, however in pyln this became a problem for some tests,
since we use absolute paths in the testing framework. It's also a rather
strange quirk to expose to users.

This patch introduces a `UnixSocket` abstraction that attempts to work around
these limitations by aliasing the directory containing the socket into
`/proc/self/fd` and then connecting using that alias.

It was inspired by Open vSwitch code here https://github.com/openvswitch/ovs/blob/master/python/ovs/socket_util.py

Jarret Dyrbye d712f732d8 pylightning - allow unicode symbols in the description to be passed as-is to the daemon
addresses issue #2753.

Formatting the JSON with the default parameters will escape the unicode
symbols in a way that c-lightning won't allow, leading to an exception.

Changelog-Fixed: `pylightning` now handles unicode characters in JSON-RPC requests and responses correctly.
