Allows us to clean up an in-progress open that we won't be completing
Changelog-Added: EXPERIMENTAL JSON-RPC: Permit user-initiated aborting of in-progress opens. Only valid for not-yet-committed opens and RBF-attempts
The semantics don't change, since `lightningd` will use false as
default as well, however setting it to something other than `None`
causes the RPC library to include the parameter in the query, and
since the parameter was introduced only in 0.9.3 and pyln may be used
with older versions this then results in an error about an unknown
parameter.
Setting this to `None` makes sure pyln filters out the argument before
calling.
Changelog-Fixed: pyln: Fixed an error when calling `listfunds` with an older c-lightning version causing an error about an unknown `spent` parameter
In the case where you want a PSBT and also want the output to be added
as a change address, use `excess_as_change` = true.
Generates a change address to use. If you want to pay the excess
elsewhere, you will have to add separately.
Changelog-Added: JSON-RPC: Add new parameter `excess_as_change` to fundpsbt+utxopsbt
This is required if we want to create a "bouncer" plugin (in my copious free time!)

Changelog-Added: JSON-RPC: `invoice` now takes an optional `cltv` parameter.
A fractional satoshi value isn't really useful; rounding up loses
precision but that's why you called "whole satoshi", wasn't it?
Changelog-Changed: pyln-client: Millisatoshi has new method, `to_whole_satoshi`; *rounds value up* to the nearest whole satoshi
We need to use it for the 'df_accepter' plugin, so we get the feerate
correct.
Changelog-Added: pyln-client: `fundpsbt`/`utxopsbt` now support `min_witness_weight` param
This only adds a test that currently makes sure its not possible
to init a Millisatoshi by a floating number.
Discussion:
As @gallizoltan points out, initialization with a float should be possible:
https://github.com/ElementsProject/lightning/pull/4273#discussion_r540369093
> Millisatoshi(5) / 2 currently works, and removes the half msat.
> So, I think Millisatoshi(5 / 2) should be the same.
Before this patch this fails: `Millisatoshi(42) / Millisatoshi(2)`
This is an operation that should return the ratio between the two
operands as a float number. Same goes for __floordiv__ operator `//`.
Changelog-None
We promised to deprecate the old "destination satoshi feerate utxos"
variant some time on mid-2020 so let's do just that. `txprepare`
doesn't parse it either anymore.
Changelog-Changed: pyln: `txprepare` no longer supports the deprecated `destination satoshi feerate utxos` call format.
We also sanity check that response id matches our request.

Changelog-Added: pyln: pyln.client handles and can send progress notifications.
`openchannel_signed` and `openchannel_update` which allow a user to
continue a openchannel or kick off the completion of a openchannel.
`openchannel_update` should be called until it returns with
`commitments_secured`.
Finally, extends the 'close_to' functionality up to the flagship 'open a
channel' command.
Changelog-Added: JSON-API `fundchannel` now accepts an optional 'close_to' param, a bitcoin address that the channel funding should be sent to on close. Requires `opt_upfront_shutdownscript`
Several times we had issues with plugins not being able to re-encode an RPC
result because they forgot to use the custom encoder class. This allows us to
patch the JSONEncoder when we start the RPC or the plugin and automagically
support classes that provide a `to_json` method.
Fixes: #2679
Changelog-Added: JSON-RPC: New `multiwithdraw` command to batch multiple onchain sends in a single transaction. Note it shuffles inputs and outputs, does not use BIP69.
This is an extra safety check for dual funding, where we only want to sign
the inputs we provided!

Changelog-Added: JSON-RPC: `signpsbt` takes an optional `signonly` array to limit what inputs to sign.
Required for dual funding where the opener sets it.
Changelog-Added: JSON-RPC: `fundpsbt` takes a new `locktime` parameter
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
fundpsbt forces the caller to manually add their weight * feerate
to the satoshis they ask for. That means no named feerates.
Instead, create a startweight parameter and do the calc for them
internally, and return the feerate we used (and, while we're at it,
the estimated final weight).
This API change is best done now, as it would otherwise have to
be appended as a parameter.

Changelog-Added: JSON-RPC: new call `signpsbt` which will add the wallet's signatures to a provided psbt
Changelog-Added: JSON-RPC: new call `sendpsbt` which will finalize and send a signed PSBT
Reserve and unreserve wallet UTXOs using a PSBT which includes those
inputs.
Note that currently we unreserve inputs everytime the node restarts.
This will be addressed in a future commit.
Changelog-Added: JSON-RPC: Adds two new rpc methods, `reserveinputs` and `unreserveinputs`, which allow for reserving or unreserving wallet UTXOs
I quickly ran through the comments in lightning.py and saw a few small inconsistencies:
- upper/lower case for the "B" in "Bitcoin" unified (see https://github.com/lnbook/lnbook/pull/98)
- added missing "." after a complete sentence
- removed unnecessary double spaces
ChangeLog-Added: New `getsharedsecret` command, which lets you compute a shared secret with this node knowing only a public point. This implements the BOLT standard of hashing the ECDH point, and is incompatible with ECIES.
Fixes: #3192
Changelog-Added: `waitanyinvoice` now supports a `timeout` parameter, which when set will cause the command to fail when the timeout is reached; can set this to 0 to fail immediately if no new invoice has been paid yet.
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
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.
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

enables the ability to push_msat on fundchannel
Changelog-Added: RPC: `fundchannel` and `fundchannel_start` can now accept an optional parameter, `push_msat`, which will gift that amount of satoshis to the peer at channel open.
Thanks to @t-bast, who made this possible by interop testing with Eclair!
Changelog-Added: Protocol: can now send and receive TLV-style onion messages.
Changelog-Added: Protocol: can now send and receive BOLT11 payment_secrets.
Changelog-Added: Protocol: can now receive basic multi-part payments.
Changelog-Added: RPC: low-level commands sendpay and waitsendpay can now be used to manually send multi-part payments.

addresses issue #2753.
Formatting the JSON with the default parameters will escape the unicode
symbols in a way that c-lightning won't allow, leading to an exception.
Changelog-Fixed: `pylightning` now handles unicode characters in JSON-RPC requests and responses correctly.
This should not affect any consumer of the API since we just shift the actual
implementation from one side to the other, and keep aliases in place so
scripts don't break.
We also bump the version number from 0.0.7.3 to 0.7.4 which allows us to be in
sync with c-lightning itself, and remove the superfluous `0` in front.
