e791efe23b coin-mvt: remove all the spend-tracking
We're not going to do 'spend tracks' any more; instead we'll emit an
event whenever an output is included in a broadcast tx

(even if the broadcast fails!!)

f936fa926f plugins: simplify shutdown loop, simply close the db
The only thing that needs ld->wallet after this is destroy_invoices_waiter (off jsonrpc)
Could not find any other destructors (destroy_*) that need wallet or db access after this.
Any db access would now segfault.

96f28323bd Set default port according to network
The idea is to have different default ports for different networks.

Current default port is `9735` for everything. Let's use it for
the mainnet and reuse the difference added to the default port
from `rpc_port` values in `bitcoin/chainstate.c`.

Testnet would be `19735` (adding rpc_port - 8332 = `10000`).

Signet would be `39735` (adding rpc_port - 8332 = `30000`).

Regtest would be `19846` (adding rpc_port - 8332 = `10111`).

With Vincenzo's kind pair-programming help over tmate.

Two other commits were squashed into this one so that bisecting
never ends up in half-baked state:

1. chainparams: Fix regtest default rpc_port

   bitcoind -help says this:

    -rpcport=<port>
         Listen for JSON-RPC connections on <port> (default: 8332, testnet:
         18332, signet: 38332, regtest: 18443)

2. test_gossip: Default port for regtest

   hex: 2607 is now .... (could be 4d86 but Elements uses another port)
   dec: 9735 is now any port (could be 19846 ^^ but now is for any port)

   The lines which were binding to default port were removed as the
   default port is different on each network.

NOTE: Remember not to modify gossip_store tests which loads everything raw
      including the checksums.

Changelog-Changed: If the port is unspecified, the default port is chosen according to used network similarly to Bitcoin Core.

4ffda340d3 check: make sure all files outside contrib/ include "config.h" first.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).

config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

e7b263304e lightningd: Send updated onion spec messages.
It's very similar to the previous, but there are a few changes:

1. The enctlv fields are numbered differently.
2. The message itself is a different number.

The onionmsg_path type is the same, however, so we keep that constant
at least.

The result is a lot of cut & paste, but we will delete the old one
next release.

b3af5f5a2c spec: import latest onionmessage spec, based on routeblinding.
This is from 6e99c5feaf60cb797507d181fe583224309318e9

We renamed the enctlv field to encrypted_recipient_data in the spec, and the
new onion_message is message 513.  We don't handle it until the next patch.

Two renames:
1. blinding_seed -> blinding_point.
2. enctlv -> encrypted_recipient_data.

We don't do a compat cycle for our JSON APIs for these experimental
features only used by our own plugins, we just rename.

ae4623c21a lightingd: removal of sigchild_handler in shutdown now also closes its pipe

5f69674faa lightningd: shutdown plugins after subdaemons and assert no write access to db
because:
    - shutdown_subdaemons can trigger db write, comments in that function say so at least
    - resurrecting the main event loop with subdaemons still running is counter productive
      in shutting down activity (such as htlc's, hook_calls etc.)
    - custom behavior injected by plugins via hooks should be consistent, see test
      in previous commmit

    IDEA:

    in shutdown_plugins, when starting new io_loop:

    - A plugin that is still running can return a jsonrpc_request response, this triggers
      response_cb, which cannot be handled because subdaemons are gone -> so any response_cb should be blocked/aborted

    - jsonrpc is still there, so users (such as plugins) can make new jsonrpc_request's which
      cannot be handled because subdaemons are gone -> so new rpc_request should also be blocked

    - But we do want to send/receive notifications and log messages (handled in jsonrpc as jsonrpc_notification)
      as these do not trigger subdaemon calls or db_write's
      Log messages and notifications do not have "id" field, where jsonrpc_request *do* have an "id" field

    PLAN (hypothesis):
    - hack into plugin_read_json_one OR plugin_response_handle to filter-out json with
      an "id" field, this should
      block/abandon any jsonrpc_request responses (and new jsonrpc_requests for plugins?)

  Q. Can internal (so not via plugin) jsonrpc_requests called in the main io_loop return/revive in
     the shutdown io_loop?
  A. No. All code under lightningd/ returning command_still_pending depends on either a subdaemon, timer or
     plugin. In shutdown loop the subdaemons are dead, timer struct cleared and plugins will be taken
     care of (in next commits).

 fixup: we can only io_break the main io_loop once

ChangeLog-Fixed: We now no longer self-limit the number of file descriptors (which limits the number of channels) in sufficiently modern systems, or where we can access `/proc` or `/dev/fd`.  We still self-limit on old systems where we cannot find the list of open files on `/proc` or `/dev/fd`, so if you need > ~4000 channels, upgrade or mount `/proc`.
