Generalize things a bit so OPTIONAL_FEATURE() and COMPULSORY_FEATURE()
work with either odd or even features, then explicitly use OPTIONAL_FEATURE
in our internal feature array.

This is the normal convention for this type; it makes using converters
a little easier. See next patch.

This is probably worth preventing.
1. Our depth estimate would be inaccurate possibly leading to us
timing out too early.
2. If we're not up-to-date our onchain funds are unknown.
3. We wouldn't be able to send or receive HTLCs until we're synced anyway.

The way we build transactions, serialize them, and compute fees depends on the
chain we are working on, so let's add some context to the transactions.

The `runtest` command takes a JSON onion spec, creates the onion and decodes
it with the provided private keys. It is fully configurable and can be used
for the test-vectors in the spec.

This is all it takes on the read side to use multiple frames. We are
overshooting the padding a bit since we can at most use 16 additional frames,
but ChaCha20 is cheap.

Shouldn't be used directly, but really useful for testing, since we can just
cram a huge payload in without having to be valid. And we don't have a TLV
spec yet.

This is just taking the existing serialization code and repackaging it in a

`struct sphinx_path` serves as a container for all the routing related
information, with a couple of constructors that can be used for normal
operation or testing (with pre-determined `session_key`).

For the multi-frame support we need to introduce the FRAME_SIZE parameter and
I took the opportunity to fix up some of the naming.

It assumes the head of the array is the object/array we want to remove from,
but that's not true if we're trying to remove from a sub-object.

The spec says to close the channel if they send us an error, but we
need to be more lenient to preserve channels with other
implementations.

Our previous param support was a bit limited in this case.
We create a dev- command multiplexer, so we can exercise it.

updates the bolt version to 6639cef095a2ecc7b8f0c48c6e7f2f906fbfbc58.
this requires us to use the new bolt parser at generate-bolt.py
and updates to all of the type specifications (ie. from u8 -> byte)
And clean up some dev ones which actually happen (mainly by calling
channel_fail_permanent which logs UNUSUAL, rather than
channel_internal_error which logs BROKEN).

This happened on Travis, and the gossip_store was a suspicious 4096
bytes long. This implies they're using some non-atomic filesystem
(gossipd always does atomic writes to gossip_store), but if they are,
others surely are too.

We're going to need this for P2WSH scripts. pull it out into
a common file plus adopt the sanity checks so that it will allow for
either P2WSH or P2WPKH (previously only encoded P2WPKH scripts)
These are generalized from our internal implementations.
The main difference is that 'struct json_escaped' is now 'struct
json_escape', so we replace that immediately.
The difference between lightningd's json-writing ringbuffer and the
more generic ccan/json_out is that the latter has a better API and
handles escaping transparently if something slips through (though
it does offer direct accessors so you can mess things up yourself!).
