This cleans up the boutique handling of features, and importantly, it
means that if a plugin says to offer a feature in init, we will now
*accept* that feature.
Changelog-Fixed: Plugins: setting an 'init' feature bit allows us to accept it from peers.

This restriction was removed from the spec as of
86c2ebcc5973a4133d3ce4d80ae1c203061a1646.
We also fix up some strange formatting in that part of the documentation.
Changelog-changed: We now announce multiple addresses of the same type, if given.

Changelog-Removed: JSON: `listnodes` `globalfeatures` output (`features` since in 0.7.3).
Changelog-Removed: JSON: `listpeers` `localfeatures` and `globalfeatures` output (`features` since in 0.7.3).
Changelog-Removed: JSON: `peer_connected` hook `localfeatures` and `globalfeatures` output (`features` since in 0.7.3).
So we can't tell people they should use amount, until v0.8.2 is
released. Another 6 months before we can deprecated the 'satoshi'
field here :(

Changelog-Removed: JSON: `fundchannel` and `fundchannel_start` `satoshi` parameter removed (renamed to `amount` in 0.7.3).
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.
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.
This allows us to set more fine-grained feerate for onchain resolution.
We still give it the same feerate for all types, but this will change as
we move feerates to bcli.
My node crashed as follows:
lightningd: lightningd/peer_control.c:957: peer_connected: Assertion `!peer->uncommitted_channel' failed.
In the logs I found:
Running lightning_openingd: Cannot allocate memory
Which reveals that we're not freeing uc in that path!
Changelog-Fixed: Fix assertion on reconnect if we fail to run openingd.

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.
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).
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.
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
Some tests may not spawn a node at all, so make sure that our assumption that
the directory exists in the fixture cleanup is correct by creating the
directory.

It is ok to change the values because they are approximate anyway. Thus,
explicitly typecast to `double` to silence the warning without changing
behavior.
Changelog-None
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)
For messages, we use the onion but payload lengths 0 and 1 aren't special.
Create a flag to disable that logic.

Plus, it's a bit cleaner rather than creating a tmp tal array.
