Christian Decker b68acb8cf0 opts: Add option to register extra TLV types to accept
Incoming HTLCs are rejected by the HTLC logic if the payload contains
an even type that `lightningd` doesn't recognize. This is to prevent
us from accidentally accepting a payment that has extra semantics
attached (for example if we get a keysend payment and don't know what
to do with the TLV field containing the message we should reject it,
otherwise the overall semantics of the message delivery fail).

Rusty Russell d7e8e220e6 lightningd: clean up listconfigs output.
1. Hide the now-deprecated enable-autotor-v2-mode option.
2. Really don't print dev- options.
3. Don't print true and false as strings in some cases.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Fixed: JSON-RPC: `listconfigs` would list some boolean options as strings `"true"` or `"false"` instead of using JSON booleans.

Antoine Poinsot fe8074c8c3 Refuse to parse v2 onion addresses without deprecated_apis
Tor v2 hidden services have been deprecated for a while:
https://blog.torproject.org/v2-deprecation-timeline .

This prevents user from being able to set them in the configuration
and to connect to them while still letting us be able to parse them
for gossip.

Changelog-Deprecated: lightningd: v2 Tor addresses.  Use v3.  See https://blog.torproject.org/v2-deprecation-timeline.

Rusty Russell 3ccb6d6e7a Makefile: update to latest BOLT versions.
The main change which affects us is that 2016 blocks to forget a channel
is a fixed number in the spec; we make this clear by renaming the
(developer-only) max_funding_unconfirmed to dev_max_funding_unconfirmed
and making it compile DEVELOPER only.

Rusty Russell cc6d2afe21 Experimental option option_shutdown_wrong_funding: help me, I screwed up!
It's not unheard of for people to give the wrong funding tx to us,
getting their funds stuck.  Interestingly, we can allow mutual close
using a different txid and output number as long as they (solely)
funded the channel, and the channel hasn't been used.

This defines a "play area" feature to do just that.

Rusty Russell 0056dd7557 lightningd: disallow --daemon without --log-file.
From #clightning:

    (11:24:10) andytoshi: hiya, i'm trying to set up a new lightningd node, and when i run lightningd --network=bitcoin --log-level=debug --daemon
    (11:24:17) andytoshi: i get errors of the form fetchinvoice: Malformed JSON reply '2021-01-25T00:51:16.655Z DEBUG   plugin-offers: disabled itself at init: offers not enabled in config
    (11:24:43) andytoshi: there are a couple variants of this, but always some form of "something: failed to parse <a log line> as json"

Indeed, we close stdout, and it ends up being reused for some plugin.
But the real problem is that we log to stdout by default, which doesn't
make sense.  If they really want to discard logs, they can use
--log-file=/dev/null.

niftynei 21122af3a8 dev-force-features: adds a second valid format for forcing features
The previous dev-force-features forced you to explicitly declare every
desired feature bit in an array, for each set.

Here, we allow you to also denote adding/subtracing a feature bit
by just passing in the number of the bit to flip and the direction to
turn it. e.g.

	'dev-force-features': '+223'

Will turn on opt_dual_fund/odd.

	'dev-force-features': '-16'

Will flag off opt_basic_mpp.

Rusty Russell 9b9e830780 lightningd: attach plugins natively to the command which started it.
This will let us unify the startup and runtime-started infrastructure.

Note that there are two kinds of notifications:
1. Starting a single plugin (i.e. `plugin start`)
2. Starting multiple plugins (i.e. `plugin rescan` or `plugin startdir`).

In the latter case, we want the command to complete only once *all*
the plugins are dead/finished.

We also call plugin_kill() in all cases, and correctly return afterwards
(it matters once we use the same paths for dynamic plugins, which don't
cause a fatal error if they don't startup).

right moment, instead of guessing. The `fflush` is also useful for debugging
if a user ever pipes the output to a file it'd get buffered and the user would
wait forever. The same applies for automated systems such as `expect` or
`pexpect` based scripts that enter the password on prompt.
