This avoids having to re-serialize the block header just to compute the
hash. It also frees us from having to carry around all the details in the
header and we can hand around a minimal version.
As per the spec (https://www.jsonrpc.org/specification#request_object)
```
A rpc call is represented by sending a Request object to a Server. The Request object has the following members:
jsonrpc
A String specifying the version of the JSON-RPC protocol. MUST be exactly "2.0".
```
Changelog-fixed: pyln now includes the "jsonrpc" field to jsonrpc2 requests
Generally I prefer structures over u8, since the size is enforced at
runtime; and in several places we were doing conversions as the code
using Sphinx does treat struct secret as type of the secret.
Note that passing an array is the same as passing the address, so
changing from 'u8 secret[32]' to 'struct secret secret' means various
'secret' parameters change to '&secret'. Technically, '&secret' also
would have worked before, since '&' is a noop on array, but that's
always seemed a bit weird.

This makes it clear we're dealing with a message which is a wrapped error
reply (needing unwrap_onionreply), not an already-wrapped one.

I really want a type which means "I am a wrapped onion reply" as separate
from "I am a normal wire msg". Currently both user u8 *, and I got very
confused trying to figure out where each one was an unwrapped error msg,
or where it still needed (un)wrapping.

Changelog-Fixed: Detect a previously non-permanent error (`final_cltv_too_soon`) that has been merged into a permanent error (`incorrect_or_unknown_payment_details`), and retry that failure case in `pay`.
This is needed to fully implement handling of blockheight disagreements
between us and payee.
If payee believes the blockheight is higher than ours, then `pay`
should wait for our node to achieve that blockheight.
Changelog-Add: Implement `waitblockheight` to wait for a specific blockheight.
Add towire_int() and fromwire_int() functions to "(de)serialize"
"int". This will only work as long as both the caller of towire_int()
and the caller of fromwire_int() use the same in-memory representation
of signed integers and have the same sizeof(int).
Changelog-None
Add "peer not connected" and "unknown peer" as error codes, so that
users can check against numeric error codes instead of textual error
messages.
Will ease https://github.com/ElementsProject/lightning/issues/3366
Changelog-None
Now that c-lightning is in the FreeBSD ports system (\o/)
update the installation instructions, which basically boil down
to just `pkg install c-lightning`.
Changelog-None
Before this change `make` would build everything but the docs.
They would be built during `make install` which is unexpected.
Add a dependency to `doc-all` to the `default` target so that docs are
build together with the rest of the programs. Leave the `install-data`
as is, to still build the docs if they are not built yet during install.
Changelog-None
`wallet_payment_store` would free the `wallet_payment` instance which would
then cause us to reload it from the DB. Instead of doing the store->free->load
dance we now tell `wallet_payment_store` whether it should take ownership and
leave it alone if not.
Passing the payment around instead of referencing it through payment_hash and
partid is a nice side-effect.
`wallet_payment_store` frees the unstored payment after it has stored it, but
we still need that instance for our notifications. This is the smallest
possible fix, but I plan to refactor this out.
Changelog-Changed: plugin: `notify_sendpay_success` and `notify_sendpay_failure` are now always called, even if there is no command waiting on the result.
We clone the test above, but this time we don't attach waiters (they'd be racy
anyway), and we wait for the notification to be called. This fails, but is
fixed in the next two commits.
TIL: `rename` doesn't like its source and target to be on different
partitions. This was causing the `hsmtool` tests to fail whenever we ran them
on a different partition than the lightning-dir (e.g., `/dev/shm` for faster
testing), because we made the backup copy in the current working directory.
This changes this and creates the backup next to the original file, which has
a reasonable chance to be on the same partition.
Changelog-Changed: hsmtool: The `hsmtool` now creates its backup copy in the same directory as the original `hsm_secret` file.
Valgrind doesn't really like crashes if compiled without DEVELOPER since that
seems to compile out the debug symbols, resulting in the following error:
```
Optimistic lock on the database failed. There may be a concurrent access to the database. Aborting since concurrent access is unsafe.
