158d2212c2 closingd: configurable closing fee negotiation step
When negotiating the transaction fee for closing a channel [1], we used
to always pick the middle of the range between our proposal and the
peer's proposal.

Introduce a new option `fee_negotiation_step` to the close command, so
the peer who initiates the close can choose his back off step.

Partially resolves https://github.com/ElementsProject/lightning/issues/3270

[1] https://github.com/lightningnetwork/lightning-rfc/blob/master/02-peer-protocol.md#closing-negotiation-closing_signed

Changelog-Added: New optional parameter to the `close` command to control the closing transaction fee negotiation back off step

7c0af81c21 bcli: use a more urgent feerate for HTLCs and penalty transactions
A CONSERVATIVE/3 target for them.

Some noisy changes to the tests as we had to update the estimatesmartfee
mock.

Changelog-Changed: We now use a higher feerate for resolving onchain HTLCs and for penalty transactions

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.

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.

Christian Decker
a13591400a pyln-client: Add facility to register featurebits from plugins
we have 4 venues in which we can add features, 3 of which are unilaterally
controlled (`init`, `node_announcement`, and `invoices`) the
`channel_announcement` is co-signed by both parties, so we can't add
featurebits without additional coordination overhead.

Each location is encoded as a key-value pair in a dict called `featurebits` in
the manifest (omitted if no custom featurebits are set).

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

dc5a1ad664 fix: normalize pip requirements
This will change some `requirements.txt` of pyln-testing in a way that
it does not require different package version i.e. to `tests/requirements.txt`.

The reason for this is that users are not forced to hassle with pyenv
or virtualenv and could just use `--user`.

pip install --user -r tests/requirements.txt -r contrib/pyln-testing/requirements.txt
