This lets us do more flexible filtering in the next patch. But it also
keeps some weird logic out of gossipd.

This increments the `data_version` upon committing dirty transactions, reads
the last data_version upon startup, and tracks the number in memory in
parallel to the DB (see next commit for rationale).
Changelog-Changed: JSON-RPC: Added a `data_version` field to the `db_write` hook which returns a numeric transaction counter.

Changelog-Added: RPC: `fundchannel` and `fundchannel_start` can now accept an optional parameter, `push_msat`, which will gift that amount of satoshis to the peer at channel open.
Thanks to @t-bast, who made this possible by interop testing with Eclair!
Changelog-Added: Protocol: can now send and receive TLV-style onion messages.
Changelog-Added: Protocol: can now send and receive BOLT11 payment_secrets.
Changelog-Added: Protocol: can now receive basic multi-part payments.
Changelog-Added: RPC: low-level commands sendpay and waitsendpay can now be used to manually send multi-part payments.

Indeed, if you waitsendpay without specifying a partid, you are waiting
for 0, which may not exist. Clarify the error msg.

We only tested exactly two equal-size payments; indeed, our finalhop
test was backwards. We only complain if the final hop pays more than
twice msat (technically, this test is still too loose for mpp: the
spec says we should sum to the exact amount).

AFAICT this only "worked" previously because replay htlc simply failed

This isn't plumbed in yet, but the idea is that every htlc gets put
into a "set" and then we process them once the set is satisfied. For
the !EXPERIMENTAL_FEATURES, the set is simply always size 1.

Explicit #if EXPERIMENTAL_FEATURES check in case we enable them at different

msatoshi was used to indicate the amount the invoice asked for, but
for parallel sendpay it's required, as it allows our sanity check of
limiting the total payments in flight, ie. it becomes
'total_msat'.
There's a special case for sendonion, which always tells us the value is 0.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We currently refuse a payment if one is already in flight. For parallel
payments, it's a bit more subtle: we want to refuse if it we already have
the total-amount-of-invoice in flight.
So we get all the current payments, and sum the pending ones.

Because my node runs under valgrind, it can take quite a while to
sync; nodes tend to disconnect and reconnect if you block too long.
This is particularly problematic since we often update fees: when the
other side sends its commitment_signed we block.
In particular, this triggers the corner case we have where we
update_fee twice, disconnecting each time, and our state machine gets
confused (which is why we never saw this exact corner case before this
change in 0.7.3!).

Now "raw_payload" is always the complete string (including realm or length
bytes at the front).
This has several effects:
1. We can receive an decrypt an onion which is grossly malformed.
2. We can still hand this to the htlc_accepted hook.
3. We then fail it unless the htlc_accepted accepts it manually.
4. The createonion API now takes the raw payload, and does not know
anything about "style".
The only caveat is that the sphinx code needs to know the payload
length: we have a call for that, which simply tells it to copy the
entire onion (and treat us as the final node) if it's invalid.

If we initiated the payment using an externally generated onion we don't know
what the final hop gets, or even who it is, so we don't display the amount in
these cases. I chose to show `null` instead in order not to break dependees
that rely on the value being there.
If we can't decode the onion, because the onion got corrupted or we used
`sendonion` without specifying the `shared_secrets` used, the best we can do
is tell the caller instead.
This means that c-lightning can now internally decrypt an eventual error
message, and not force the caller to implement the decryption. The main
difficulty was that we now have a new state (channels and nodes not specified,
while shared_secrets are specified) which needed to be handled.
