it's that time of year (merry xmas!)
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.

Now "raw_payload" is always the complete string (including realm or length
bytes at the front).
This has several effects:
1. We can receive an decrypt an onion which is grossly malformed.
2. We can still hand this to the htlc_accepted hook.
3. We then fail it unless the htlc_accepted accepts it manually.
4. The createonion API now takes the raw payload, and does not know
anything about "style".
The only caveat is that the sphinx code needs to know the payload
length: we have a call for that, which simply tells it to copy the
entire onion (and treat us as the final node) if it's invalid.

It has a whole *two paragraphs* on it:
*feerate* is an optional feerate used for the opening transaction and as
initial feerate for commitment and HTLC transactions. It can be one of
the strings *urgent* (aim for next block), *normal* (next 4 blocks or
so) or *slow* (next 100 blocks or so) to use lightningd’s internal
estimates: *normal* is the default.
Otherwise, *feerate* is a number, with an optional suffix: *perkw* means
the number is interpreted as satoshi-per-kilosipa (weight), and *perkb*
means it is interpreted bitcoind-style as satoshi-per-kilobyte. Omitting
the suffix is equivalent to *perkb*.

Changelog-Added: Added `createonion` and `sendonion` JSON-RPC methods allowing the implementation of custom protocol extensions that are not directly implemented in c-lightning itself.
Also pulls in a new onion error (mpp_timeout). We change our
route_step_decode_end() to always return the total_msat and optional
secret.
We check total_amount (to prohibit mpp), but we do nothing with
secret for now other than hand it to the htlc_accepted hook.

Changelog-changed: .lightningd plugins and files moved into <network>/ subdir
Changelog-changed: WARNING: If you don't have a config file, you now may need to specify the network to lightning-cli

This lets you have a default, but also a network-specific config.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-changed: Options: `config` and <network>/`config` read by default.
lightning-cli is going to need to know what network we're on, so
it will need to parse the config files. Move the code which does
the initial bootstrap parsing into common, as well as the config
file parsing core.

Rounds out the application of `upfront_shutdown_script`, allowing
an accepting node to specify a close_to address.
Prior to this, only the opening node could specify one.
Changelog-Added: Plugins: Allow the 'accepter' to specify an upfront_shutdown_script for a channel via a `close_to` field in the openchannel hook result
Spaces just make life a little harder for everyone.
(Plus, fix documentation: it's 'jsonrpc' not 'json' subsystem).

As suggested by @cdecker, but also did a bit of minor reformatting.
I don't like the excessive indenting in our man pages though,
but that's a separate problem.

This allows finegrained logging control of particular subdaemons or
subsystems.
To do this, we defer setting the logging levels for each log object
until after early argument parsing (since e.g. "bitcoind" log object
is created early).

Changelog-changed: Options: log-level can now specify different levels for different subsystems.
Default is legacy. If we have future styles, new strings can be defined,
but for now it's "tlv" or "legacy".

Changelog-changed: JSON API: `htlc_accepted` hook has `type` (currently `legacy` or `tlv`) and other fields directly inside `onion`.
Changelog-deprecated: JSON API: `htlc_accepted` hook `per_hop_v0` object deprecated, as is `short_channel_id` for the final hop.
When doing the random walk through the channel, we now add the fees
(both the base and the proportional one) for that channel in addition to
the cltv delta.
Changelog-Added: Payment amount fuzzing is restored, but through shadow routing.
Since the `CHANGELOG.md` file is a major source for merge conflicts I decided
to build a tiny tool that generates the entries for the changelog
automatically from the commit messages.
I'm not sure what went wrong, but the first RC I cut had some trouble
with the tag being picked up with `git describe`, I think it was missing
a 'tag message'. I'm not sure what caused this.
This commit breaks up the first git tag procedure to have the releaser
verify that the tag command works as intended (and sensitizes them to
checking this for subsequent release cuts, if necessary)
Takes advantage of upfront-shutdown-script to permit users to
specify the close-to address for a channel at open, by adding
a `close_to` field to `fundchannel_start`.
Note that this only is in effect if `fundchannel_start` returns
with `close_to` set -- otherwise, peer doesn't
support `option_upfront_shutdown_script`.
They're a little subtle, so let's spell out exactly what checkmessage
means. In particular, we avoid discussing key derivation from a
signature, as it tends to get people (like me!) into trouble: we
describe it instead as iterating through every known node.

This is mainly an internal-only change, especially since we don't
offer any globalfeatures.
However, LND (as of next release) will offer global features, and also
expect option_static_remotekey to be a *global* feature. So we send
our (merged) feature bitset as both global and local in init, and fold
those bitsets together when we get an init msg.

Add a new startup option which will, if set, prompt the user for a
password to derive a key from. This key will later be used to encrypt
and/or decrypt `hsm_secret`.
This was made a noarg option even if it would have been preferable to
let the user the choice of how to specify the password. Since we have
to chose, better to not let the password in the commands history.
