This centralizes the setup.py file, and parametrizes it so it can
auto-detect which bolt we are building. It also uses trick 3 from [1]
to avoid importing the package itself during the manifest creation,
which'd cause an import error due to missing dependencies.
[1] https://packaging.python.org/guides/single-sourcing-package-version/
This would lead to errors about missing dependencies when attempting
to install using `pyhon setup.py install`. This is because the
`setup.py` file effectively is the manifest file used to discover
which dependencies are needed, so when using it to detect dependencies
we obviously don't have them yet.
See https://packaging.python.org/guides/single-sourcing-package-version/
They are currently not installable due to circular dependencies and
stuff, so we just add their source to the path and lnprototest will
pick them up from there.
This allows to not have to worry about the source of the installation,
and we always use our in-tree version. It also means we pull in the
requirements.txt files through the setup.py and don't need to
replicate them.
Instead of "only check suffix quotes when EXPERIMENTAL_FEATURES", make
it so we only check suffix quotes if you override BOLTVERSION on the
cmdline.
Before this, "make check-source-bolt" was effectively a NOOP with
--enable-experimental-features.

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.

They're not defined to be, though we've not seen this on Linux (testing
showed that it is page-level atomic, which means it can still happen across
page boundaries though!). This was pointed out by whitslack in
https://github.com/ElementsProject/lightning/issues/4288
In practice, this just means not complaining when it happens, and also
not trying to get tricky to use it on MacOS (we can safely seek & write,
since we're single-threaded).

Changelog-Removed: Removed bogus UNUSUAL log about gossip_store 'short test'.
We weren't writing out the length of a nested subtype's
dynamicarraylenght, now we do. The trick is to iterate through the
fields on a subtype (since the length field is added separately)
and to also iterate down through the otherfield values as we 'descend'
It's unlikely but possible that a race condition will result in us not
being at the 'secured' state yet here.
Crashlogs. All required msgs are received (in order)
from peers, but the crash suggests they weren't relayed/processed by the
spender plugin in the order received.
WIRE_TX_SIGNATURES is passed the the plugin via a notification;
WIRE_COMMITMENT_SIGNED is returned as the result of an RPC call.

Fixes#4455
This means remembering the connection direction. We also use the address to try
to reconnect, which we shouldn't bother with if they connect to us.
For peers from the database, we currently always save the addr: we shouldn't really
do this if they connected to us, since it's not useful for reconnecting (we don't
show the addr in JSON reply to listpeers unless we're connected, so it's only an
internal issue). This is left for future work.

This matters: if we connected, the address is probably usable for future connections.
But if they connected, the port is probably not (but the IP address may be).
Changelog-Added: JSON-RPC: `connect` returns "direction" ("in": they iniatated, or "out": we initiated)
Changelog-Added: plugins: `peer_connected` hook and `connect` notifications have "direction" field.

If gossip_store is an incorrect version, we will recreate it: with an incorrect
version! This means we never get persistent gossip, *and* the pay plugin will
fail to map the gossip_store. Everyone will be sad.

You can now activate dual-funded channels using the
`--experimental-dual-fund` flag
Changelog-Changed: Config: `--experimental-dual-fund` runtime flag will enable dual-funded protocol on this node
This was flaky because sometimes we'd generate blocks before the funding
transaction reached the mempool.
If we wait until it's in, it works as expected.
[ Neatened to use wait_for_mempool arg --RR ]
We updated the "UNKNOWN TYPE channel_id" -> the actual channel id;
the reason for why the error fails shouldn't be restrictive (we just
know that it fails)
clang 10.0.0 (erroneously?) claims an enum_side cannot be >= NUM_SIDES.
Make it clear that we're testing the raw u8 for validity.

As @fiatjaf points out we were notifying before we were actually set
on accepting, since the hook could also still reject. Switched them
around does and calling the notification only once it's been decided
is the correct thing to do.
Changelog-Fixed: plugin: The `invoice_payment` notification was being sent before the hook was called, which could still abort it.
