This regroups questions (frequently) seen in Github issues, on IRC, and
also some I've been asked in face to face.
Changelog-Added: doc: An FAQ was added, accessible at https://lightning.readthedocs.io/FAQ.html
Christian wrote the block chain rescaning paragraph.
Lisa corrected my poor english grammar.

This is useful in general, but in particular it allows fundchannel to avoid YA
query to figure out if it can wumbo.

Changelog-Added: JSON: `connect` returns `features` of the connected peer on success.
This cleans up the boutique handling of features, and importantly, it
means that if a plugin says to offer a feature in init, we will now
*accept* that feature.
Changelog-Fixed: Plugins: setting an 'init' feature bit allows us to accept it from peers.

This restriction was removed from the spec as of
86c2ebcc5973a4133d3ce4d80ae1c203061a1646.
We also fix up some strange formatting in that part of the documentation.
Changelog-changed: We now announce multiple addresses of the same type, if given.

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.
Before this patch we used to send `double`s over the wire by just
copying them. This is not portable because the internal represenation
of a `double` is implementation specific.
Instead of this, multiply any floating-point numbers that come from
the outside (e.g. JSONs) by 1 million and round them to integers when
handling them.
* Introduce a new param_millionths() that expects a floating-point
number and returns it multipled by 1000000 as an integer.
* Replace param_double() and param_percent() with param_millionths()
* Previously the riskfactor would be allowed to be negative, which must
have been unintentional. This patch changes that to require a
non-negative number.

the tests are not possible only by having tests/requirements.txt .
Running the whole testsuite also runs contrib/pyln-proto/tests/test_invoice.py
which needs requiremnets of pyln-proto and so on.
Also requirement coincurve requires libsecp256k1-dev headers.
As most developers need all requiremtents and we should tell them.
1. GH_TOKEN is probably required to run the changelog script.
2. Note the footnotes need updating; we no longer have [Unreleased].

Changelog-Fixed: Fixed factual errors in `lightning-listchannels.7` documentation.
`delay` is ***not*** the unilateral close delay for that channel-direction!
Changelog-Changed: The hooks `db_write`, `invoice_payment`, and `rpc_command` now accept `{ "result": "continue" }` to mean "do default action", in addition to `true` (`db_write`), `{}` (`invoice_payment`), and `{"continue": true}` (`rpc_command`). The older "default" indicators are now deprecated and are now recognized only if `--deprecated-apis` is set.
Changelog-Added: lightningd: Added --subdaemon command to allow alternate subdaemons.
[ Wow, that was mammoth; 44 comments over 12 commits. Feels almost unfair to squash it into one commit, so I wanted to note @ksedgwic's perseverence here! --RR ]
* Fix usage of `echo "...\n..."` (without `-e`), generating a
broken output:
```
lightningd-config <lightningd-config.5.md>
lightningd\nlightning-autocleaninvoice.7.md <lightningd.8.md\nlightning-autocleaninvoice.7.md>
```
* Use `$(SORT)` instead of bare `sort` to avoid locale-dependent sort.
* Strip the trailing .[0-9].md without invoking sed.
* Sort all man pages as one block.
Changelog-None
ChangeLog-Fixed: Clarified about connection in documentation. Also, `fundchannel` already `connect`s if your node knows how to contact the desired peer for a few versions now, so clarify documentation about this as well.
Using it with a different value to the amount sent causes a crash in 0.8.0,
which is effectively deprecating it, so let's disallow it now.
Changelog-Changed: If the optional `msatoshi` param to sendpay for non-MPP is set, it must be the exact amount sent to the final recipient.

Before this patch we used `int` for error codes. The problem with
`int` is that we try to pass it to/from wire and the size of `int` is
not defined by the standard. So a sender with 4-byte `int` would write
4 bytes to the wire and a receiver with 2-byte `int` (for example) would
read just 2 bytes from the wire.
To resolve this:
* Introduce an error code type with a known size:
`typedef s32 errcode_t`.
* Change all error code macros to constants of type `errcode_t`.
Constants also play better with gdb - it would visualize the name of
the constant instead of the numeric value.
* Change all functions that take error codes to take the new type
`errcode_t` instead of `int`.
* Introduce towire / fromwire functions to send / receive the newly added
type `errcode_t` and use it instead of `towire_int()`.
In addition:
* Remove the now unneeded `towire_int()`.
* Replace a hardcoded error code `-2` with a new constant
`INVOICE_EXPIRED_DURING_WAIT` (903).
Changelog-Changed: The waitinvoice command would now return error code 903 to designate that the invoice expired during wait, instead of the previous -2
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.
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.
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
