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.

darosior 8cbc0038bc onchaind: a feerate per transaction type
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.

Rusty Russell 3e311b2510 lightningd: fix assert() if spawning openingd fails.
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.

Christian Decker 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.

Christian Decker 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).

Christian Decker 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 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.

lisa neigut 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)

Vasil Dimov 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.
