And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).
config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

Useful for regtest and testnet. Sure, you shouldn't use this on mainnet,
but I haven't restricted it because our users are usually pretty clever.

Changelog-Added: config: `force_feerates` option to allow overriding feerate estimates (mainly for regtest).
This makes for more useful errors. It prints where it was up to in
the guide, but doesn't print the entire JSON it's scanning.

Fixing the following error by changing 'enum feerate' to int.
lightningd/bitcoind.c:183:29: error: result of comparison of constant
8 with expression of type 'enum feerate' is always true [-Werror,
-Wtautological-constant-out-of-range-compare]
for (enum feerate f = 0; f < NUM_FEERATES; f++) {
Changelog-Fixed: compile error on macos
Changelog-Deprecated: plugin: `bcli` replacements should note that `sendrawtransaction` now has a second required Boolean argument, `allowhighfees`, which if `true`, means ignore any fee limits and just broadcast the transaction. Use `--deprecated-apis` to use older `bcli` replacement plugins that only support a single argument.
The symptom (under heavy load and valgrind) in test_plugin_command:
lightningd: common/json_stream.c:237: json_stream_output_: Assertion `!js->reader' failed.
This is because we try to call `getmanifest` again on `pay` which has not yet
responded to init.
The minimal fix for this is to keep proper state, so we can tell the
difference between "not yet called getmanifest" and "not yet finished
init".

This in addition removes the init fixed timeout hack.

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.
This avoids the getblockhash+getblock, and more importantly that was the
last functionality making use of bitcoind_getrawblock() and bitcoin_getblockhash(),
so we can also get rid of them.
This adds `getchaininfo` and `getrawblockbyheight` handling lightningd-side,
and use them in setup_topology().
We then remove legacy bitcoind_getblockcount() (we already get the count in
`getchaininfo`), bitcoind_getblockchaininfo() (it was only used in setup_topology()),
and wait_for_bitcoind() (this was specific to bitcoin-core and we assume our Bitcoin
backend to be functional if the plugin responds to `init`).
This leads to all sorts of problems; in particular it's incredibly
slow (days, weeks!) if bitcoind is a long way back. This also changes
the behaviour of a rescan argument referring to a future block: we will
also refuse to start in that case, which I think is the correct behavior.
We already ignore bitcoind if it goes backwards while we're running.
Also cover a false positive memleak.
Changelog-Fixed: If bitcoind goes backwards (e.g. reindex) refuse to start (unless forced with --rescan).

Currently the only source for amount_asset is the value getter on a tx output,
and we don't hand it too far around (mainly ignoring it if it isn't the
chain's main currency). Eventually we could bubble them up to the wallet, use
them to select outputs or actually support assets in the channels.
Since we don't hand them around too widely I thought it was ok for them to be
pass-by-value rather than having to allocate them and pass them around by
reference. They're just 41 bytes currently so the overhead should be ok.

During sync it is highly likely that we can coalesce multiple calls and share
results among them. We also report back failures for non-existing blocks early
on, so we don't run into issues with blocks that our bitcoind doesn't have
yet.

Instead of allowing all calls to `getfilteredblock` to be scheduled on the
`bitcoind` queue right away we instead add them in a separate queue, and
process a single call at a time. This limits the concurrency and avoids
thrashing `bitcoind`. At the same time we dispatch incoming results back to
all calls that were queued for that particular blockheight, reducing the
overall number of calls and an increase in overall speed.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
We will be calling the callback out of order once we fan out the results of a
single lookip to multiple calls, so being sure that everything is allocated
ahead of time is necessary.

Since we now check all P2WSH outputs in a block, this is getting quite a
common occurence, so logging just produces lots of noise.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
This will eventually replace the multi-step `getblockhash` + `getblock` +
`gettxout` mechanism, and return entire filtered blocks which can be added to
the DB, and represent the full set of P2WSH UTXOs.
