Telling `lightningd` to pass a `-datadir` to `bitcoin-cli` so it doesn't go
snooping where it doesn't belong (i.e., the user's home directory and config).

This was breaking a couple of tests if the pyln version was not synced up with
`lightningd`, so now we just warn (these are then collected when running in
pytest and highlighted).
We only support a very limited number of argument combinations, and apparently
sometimes we trigger a case we aren't handling. This adds a more useful error
message, including the params we didn't match.
So far we've always cleared the node directory when provisioning the node, but
while testing some plugins we noticed that pre-generating some files in that
directory is useful. This just adds yet another flag to `get_node` that
disables deleting any existing node directory.
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
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.
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).
if the node fails to start (and we're expecting it to) return to us the
node object anyway
we also signal to collect all of its stderr logs by setting stderr
on the tailableproc that backs the node
The `generate` has been deprecated since 0.16 and has been removed in 0.18.0
so we better use `generatetoaddress` instead, which is already what we do with
`bitcoind`. So we remove the override here.
Changelog-changed: .lightningd plugins and files moved into <network>/ subdir
Changelog-changed: WARNING: If you don't have a config file, you now may need to specify the network to lightning-cli

Spaces just make life a little harder for everyone.
(Plus, fix documentation: it's 'jsonrpc' not 'json' subsystem).

This simplifies our tests, too, since we don't need a magic option to
enable io logging in subdaemons.
Note that test_bad_onion still takes too long, due to a separate minor
bug, so that's marked and left dev-only for now.

1. Printed form is always "[<nodeid>-]<prefix>: <string>"
2. "jcon fd %i" becomes "jsonrpc #%i".
3. "jsonrpc" log is only used once, and is removed.
4. "database" log prefix is use for db accesses.
5. "lightningd(%i)" becomes simply "lightningd" without the pid.
6. The "lightningd_" prefix is stripped from subd log prefixes, and pid removed.

Changelog-changed: Logging: formatting made uniform: [NODEID-]SUBSYSTEM: MESSAGE
Changelog-removed: `lightning_` prefixes removed from subdaemon names, including in listpeers `owner` field.
A log can have a default node_id, which can be overridden on a per-entry
basis. This changes the format of logging, so some tests need rework.

Quite a few of the things in the LightningNode class are tailored to their use
in the c-lightning tests, so I decided to split those customizations out into
a sub-class, and adding one more fixture that just serves the class. This
allows us to override the LightningNode implementation in our own tests, while
still having sane defaults for other users.
We were relying heavily on NodeFactory to do some magic before instantiating
the Node with rpc and daemon initialized, that meant that we'd have to replace
all 3 classes when customizing the node to our needs. Moving that
initialization into the node itself means that the LightningNode class now can
be swapped out and customized, without having to wire everything else through.
`DEVELOPER=1` assumes that the binary has been compiled with developer set to
true, which might not be the case for plugin developers. Setting this to 0 by
default has no effect in c-lightning since we always at least set it in
`config.vars` but may prevent some issues outside.
We'll rewrite the tests to use this infrastructure in the next commit.
Changelog-Added: The new `pyln-testing` package now contains the testing infrastructure so it can be reused to test against c-lighting in external projects
We were checking against hardcoded hrp and prefixes. Now we parametrize via
the chainparams.

Since we will soon be writing the `liquid-regtest` section instead of the
`regtest` section we should make that configurable.

There were a few places we were rebuilding the config path by appending
`bitcoin.conf` to the bitcoin directory. So now we just remember it and
reference it instead.

Note the use of sqrt, which makes a 13 second timeout under Travis
(180 second), or 7 seconds normally.

We will soon have a postgres backend as well, so we need a way to control the
postgres process and to provision DBs to the nodes. The two interfaces are the
dsn that we pass to the node, and the python query interface needed to query
from tests.

It's generally clearer to have simple hardcoded numbers with an
#if DEVELOPER around it, than apparent variables which aren't, really.
Interestingly, our pruning test was always kinda broken: we have to pass
two cycles, since l2 will refresh the channel once to avoid pruning.
Do the more obvious thing, and cut the network in half and check that
l1 and l3 time out.

Throwing an exception while killing all nodes meant that
we aren't cleaning up all the nodes properly. Instead,
collect the errors, and return them back to the upper level,
where we report them and terminate as expected.
This is an issue that was raised in #2665: some of the dependencies where
causing warnings to be added to the logs about deprecated dependencies. Since
I did not get these warnings I just blanket updated all the dependencies in
the hopes of getting the warnings to resolve.

And clean up some dev ones which actually happen (mainly by calling
channel_fail_permanent which logs UNUSUAL, rather than
channel_internal_error which logs BROKEN).
