We don't have a struct symkey, though perhaps we should?

453bfbc816 json-rpc: Fix test_txprepare if running with postgres
Postgres does not guarantee that the insertion order is the returned order,
which leads us to skip outputs that have already been stolen onto the selected
utxos set, but not added to it because it isn't confirmed. This may also
happen with sqlite3 though it's a lot rarer in that case.

7201cb7315 pytest: Configure logging in a fixture to match stdout capturing
pytest captures the output by monkey patching out `sys.stdout`. This may
conflict with our use of `sys.stdout` when configuring logging, resulting in
the "Write to closed file" issue that is spamming the logs. By making the
logging configuration a fixture hopefully we always use the correct
stdout (after pytest has monkey-patched it).

cf8c972883 pyln-testing: Print a list of files if we can't remove the test dir
For some reason we fail to remove the test directory in some cases. My
hypothesis is that it is a daemon that is not completely shut down yet, and
still writes to the directory. This commit intercepts the error, prints any
files in the directory and re-raises the error. This should allow us to debug
the reappears.

42a63e4416 tx: Strengthen transaction construction checks
We roll the `elements_add_fee_output` function and the cropping of
overallocated arrays into the `bitcoin_tx_finalize` function. This is supposed
to be the final cleanup and compaction step before a tx can be sent to bitcoin
or passed off to other daemons.

This is the cleanup promised in #3491

It is ok to change the values because they are approximate anyway. Thus,
explicitly typecast to `double` to silence the warning without changing
behavior.

a08905c344 plugin tests: actually check log result + move over to '' -> true
a few things. one is that `is_in_log` returns a result rather than
enforcing a condition. so these lines all need asserts

two is that with the 'allow_deprecated_apis' option on, the python json
parser overwrites the now typed input with the later-added string
version, so the only option value present in the option key-value set is
the last, string one. the check for this has been updated to only verify
that the string version is included (i manually verified that both are
printed to the JSON message)

2b2ee87801 travis: do not cache ./external
Caching the `./external` directory means that any changes to
`external/Makefile` or any updates of the submodules in `./external/*`
would not be picked up and travis would run with old instances of those,
possibly "activating" such changes after weeks or months when the cache
is pruned eventually.

e79cda8c9a sphinx: Treat compressed onions as a standalone struct
Expands the interface to play with onions a bit more. Potentially a bit

d2688bbaf5 plugin: Unwrap the rpc_command payload
We were nesting like the following:

```json
{"params": {
  "rpc_command": {
    "rpc_command": {
    }
  }
}
```

This is really excessive, so we unwrap once, and now have the following:

```json
{"params": {
  "rpc_command": {
  }
}
```

Still more wrapping than necessary (the method is repeated in the `params`
object), but it's getting closer.

Changelog-Deprecated: JSON-RPC: Removed double wrapping of `rpc_command` payload in `rpc_command` JSON field.

66eca2ff3f lightningd: always broadcast the latest close tx
Before this patch we would only update `channel->last_tx` with the newly
proposed closure tx from the peer if the fee of the new one was lower.

In negotiations where we are at the higher end and the peer starts
lower, all peer's subsequent proposals will be higher than his initial
proposal and in this case we would never update `channel->last_tx`
and would wrongly broadcast his initial proposal at the end of the
negotiation.

Fixes https://github.com/ElementsProject/lightning/issues/3549

Changelog-Fixed: Always broadcast the latest close transaction at the end of the close fee negotiation, instead of sometimes broadcasting the peer's initial closing proposal.
