We make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds). This scheme
follows the latest draft, in which features are flagged compulsory.
We also add several helper functions.
Since uses the *even* bits (as per latest spec), not the *odd* bits,
we have some other fixups.

Implement support for liquidity ads in `funder` plugin. We set the
command line options for the leases, as well as sending the updated ads
to lightningd (who then passes them through to gossipd)
Temporarily rename old getroute to getrouteold (we will remove this).
Changelog-Changed: JSON-RPC: `getroute` is now implemented in a plugin.

Behold! An immaculately concepted plugin for configuring your node to do
amazing things*
*fund channel open requests
Changelog-Added: Plugins: Add `funder` plugin, which allows you to setup a policy for funding v2 channel open requests. Requres --experimental-dual-fund option
The fetchinvoice and offers plugins disable themselves if the option
isn't enabled (it's enabled by default on EXPERIMENTAL_FEATURES).

Changelog-Added: `experimental-offers` enables fetch, payment and creation of (early draft) offers.
Don't include exp directly, use an ifdef in common/bolt12
(like we do for peer and onion wiregen files).

This is experimental for now, but can eventually deprecated
'decodepay' and even decode other kinds of messages.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Note that we remove the redundant "is this the correct chain?"
check, since bolt11_decode and bolt12_decode do that internally
anyway (this was changed in 924cc04bd2).

Note that check-whitespace and check-bolt already do this, so we
can eliminate redundant lines in common/Makefile and bitcoin/Makefile.
We also include the plugin headers in ALL_C_HEADERS so they get
checked.

I got a corrupt file, which looked like multiple concurrent attempts
to build it. So instead, build it in one command, but also use
VERBOSE so we print correctly with V=1 (and --quiet).
Also move into plugins/ where it logically belongs.

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.
Changelog-Added: We now have `multifundchannel` as a builtin plugin command to fund multiple channels to different peers all in a single onchain transaction.

This uses `fundpsbt` and similar to simulate the txprepare command.
It has one difference (when complete), in that it those reservations
are now timed and don't get reset on restart.
It also doesn't have the restriction that `all` can only be used with
no other output, as I didn't realize that when I implemented it!
Note that change is now inserted in a random position, not sorted
into BIP69 order.

This avoids overwriting the ones in git, and generally makes things neater.
We have convenience headers wire/peer_wire.h and wire/onion_wire.h to
avoid most #ifdefs: simply include those.

We create ALL_PROGRAMS, ALL_TEST_PROGRAMS, ALL_C_SOURCES and
ALL_C_HEADERS. Then the toplevel Makefile knows which are
autogenerated (by wildcard), so it can have all the rules to clean
them or check the source as necessary.

We already duplicate a lot of code between `lightningd` and eeach
builtin plugin because we do not use .so for `common/`, but including
an object file with code that is not referenced in the executable is
fairly low-hanging size optimization fruit.
most likely unused since the switch to libwally for internal blockchain
things.
these method names were clashing with ones that are to be introduced
with some libwally cleanups, so getting rid of them pre-emptively keeps
us libwally compatible
Since we now over-write the wally malloc/free functions, we need to do
so for tests as well. Here we pull up all of the common setup/teardown
logic into a separate place, and update the tests that use libwally to
use the new common_setup core
Changelog-None
The generated wrappers will ignore the raw fields and will only consider the
shortcut fields. This function takes the raw fields and serializes them
instead.
This still uses the experimental TLV-type, but once the type is standardized
we can add detection for the new type quite easily.
Changelog-Added: pay: The `keysend` plugin implements the ability to receive spontaneous payments (keysend)
Most is taken from lightningd/bitcoind and adapted. This currently
exposes 5 commands:
- `getchaininfo`, currently called at startup to check the network and
whether we are on IBD.
- `getrawblockbyheight`, which basically does the `getblockhash` +
`getblock` trick.
- `getfeerate`
- `sendrawtransaction`
- `getutxout`, used to gather infos about an output and currently used by
`getfilteredblock` in `lightningd/bitcoind`.
