We detect whether we have the rust tooling available (mainly `cargo`)
and enable or disable the rust libraries, plugins and examples when it
is enabled. Since the rest of the Makefiles assumes that executables
have an associated header and C source file, we also needed to add a
target that we can add non-C binaries to.
On some distributions (e.g. Gnu Guix) Python packages are not installed in
some standard directory, rather they are installed in different places and
the `PYTHONPATH` variable is modified to include the different places.
So, we must not use the name `PYTHONPATH` in our `Makefile` since `make`
will replace the `PYTHONPATH` environment variable, preventing e.g.
`tools/generate-wire.py` from finding `python-mako` installed on such
distributions.
WebSocket is a bit weird:
1. It starts like an HTTP connection, but they send special headers.
2. We reply with special headers, one of which involves SHA1 of one of theirs.
3. We are then in WebSocket mode, where each frame starts with a 2-20 byte
header.
We relay data in a simplistic way: if either side sends something, we
read it and relay it synchronously. That avoids any gratuitous
buffering.

In particular, they are allowed to include .c files!
Here's `make check-units` on a maintainer-clean tree:

It also gets rid of the requirement that close negotiation fee maximum
is the old commitment transaction. We still do that, however, to
avoid surprising old peers.

This touches a lot of text, mainly to change "if `option_anchor_outputs`"
to "if `option_anchors`"

This includes the new bolt11 test vectors, and also removes the
requirement that HTLCs be less than 2^32 msat. We keep that for now
because Electrum enforced it on receive: in two releases we will stop
that too.
So no longer warn about needing mpp in that case either.

Changelog-Deprecated: Protocol: No longer restrict HTLCs to
Enable non-dev builds to send custom messages.
Preserves 'dev-' for compat-enabled builds.
Changelog-Changed: JSON-RPC: moved dev-sendcustommsg to sendcustommsg
For markdown, there's no simple comment prefix: we need a postfix too.
We also need to use "" since we want to use ' in some of the Makefiles
in future when V=1.

This includes anysegwit and the updated HTLC tiebreak test vector. It
also adds explicit wording for invalid per_commitment_secret (which
nicely matches our code already!).

If you do update-mocks in a dirty tree, the recursive make that it
uses will try to rebuild things! Suppress that.

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.
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.

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
We assume if they set this to 0 (which nobody did previously), they're
using it as a modern flag and use it to indicate when they're
finished. Otherwise, we count how many blocks they've sent and use
that to determine whether they've finished.

Changelog-Changed: Protocol: we use `sync_complete` for gossip range query replies, with detection for older spec nodes.
A new target `check-gen-updated` to verify that all derived/generated
files that were modified were also checked in. This is used on CI to
check, and is not added to `check` since it'll complain on dirty
trees, i.e., before the devs check in their changes.
